How to Change the Time and Date on a Rolex GMT-Master II (Correct Method)
A step-by-step guide explaining how to correctly change the time and date on a Rolex GMT-Master II using the jumping hour hand.
The Rolex GMT-Master II is designed differently from most automatic watches.
Thanks to its independently adjustable hour hand, you can change the time and date safely without stopping the movement if it’s done correctly.
This guide explains exactly how to change both the time and the date, without damaging the watch.
Understanding the Rolex GMT-Master II
Unlike standard date watches, the GMT-Master II features:
⭐️ A jumping local hour hand
⭐️ A 24-hour GMT hand (home time)
⭐️ A date mechanism linked to the local hour hand
This means the date changes when the hour hand passes midnight, not via a traditional quickset.
Crown Positions Explained
The crown has three positions:
1. Screwed in – normal, water-tight
2. First click out – adjusts local hour hand & date
3. Second click out – adjusts all hands together
⚠️ There is no separate quickset date wheel like on a Submariner or Datejust.
How to Change Local Time (Travelling)
This is the most common adjustment.
Step-by-Step
1. Unscrew the crown (anti-clockwise)
2. Pull the crown to the first click
3. Rotate the crown to move the hour hand forward or backward
▪️ The minute and GMT hands stay still
▪️ Accuracy is not affected
4. Push the crown back in and screw it down
✅ Safe
✅ Does not stop the watch
✅ Designed for frequent use
How to Change the Date on a Rolex GMT-Master II
Unlike most watches, the date is changed by moving the hour hand, not by a separate date-set position.
Correct Method
1. Unscrew the crown
2. Pull the crown to the first click
3. Rotate the crown forward until the hour hand passes midnight
4. Each time the hour hand crosses midnight, the date advances by one day
5. Continue until the correct date is shown
6. Push the crown back in and screw it down
💡 You can move the hour hand forwards or backwards to reach the correct date faster.
Why This Is Safe (Important)
On a GMT-Master II:
⭐️ The date mechanism is disengaged during hour-hand adjustment
⭐️ There is no traditional “danger zone” like on standard date watches
⭐️ Rolex designed this system to be used at any time of day
That said:
✅ Always turn gently
✅ Never force resistance
How to Set Home Time (GMT Hand)
This is usually done once.
Steps
1. Unscrew the crown
2. Pull to the second click
3. Set:
▪️ Minute hand
▪️ GMT hand (points to 24-hour scale)
4. Push crown back in and screw down
Common Mistakes to Avoid
⭐️ Trying to “quickset” the date like a Submariner
⭐️ Using the second crown position for daily time changes
⭐️ Forgetting to screw the crown back down
⭐️ Forcing the crown when resistance is felt
Key Takeaways
✅ Date is changed via the jumping hour hand
✅ Use first crown position only
✅ No quickset date wheel
✅ Designed for frequent time-zone changes
Final Advice
The Rolex GMT-Master II is one of the most intelligently designed travel watches ever made.
Once you understand how the hour hand and date are linked, setting it becomes fast, safe, and intuitive.

How to Maintain Your Watch Like a Pro
Learn how to maintain your watch like a professional. Simple care tips to protect accuracy, condition, and long-term value.
Whether you wear it daily or only on special occasions, your watch deserves more than just wrist time it deserves care. From vintage classics to modern automatics, proper watch maintenance not only preserves value but ensures your timepiece ticks flawlessly for years to come. Here’s how to treat your watch like the legend it is.
1.
Keep It Clean
Dust, sweat, and skin oils are your watch’s natural enemies. Clean it regularly using a soft microfiber cloth. For deeper cleaning:
Use lukewarm water and mild soap for metal bracelets (never leather!).
A soft toothbrush helps lift dirt between links or around the bezel.
Dry thoroughly with a lint-free cloth.
💡Pro Tip: Avoid using harsh chemicals or household cleaners your watch isn’t a kitchen sink.
2.
Avoid Magnetism
In today’s tech-heavy world, magnetic fields are everywhere phones, laptops, speakers. Exposure can cause your watch to run fast, slow, or stop altogether.
Keep your watch at least 6–10 inches away from strong magnets.
Invest in a demagnetiser if your watch is acting weird.
3.
Mind the Water Resistance
Just because it says “water-resistant” doesn’t mean it’s ready for a swim.
Always screw down the crown (if it has one) before water contact.
Never expose leather straps to water unless you want it to smell like regret.
Have your water resistance tested every 12 months if you swim or dive regularly.
4.
Wind It Wisely
If your watch is manual, wind it once daily, preferably in the morning.
Turn the crown slowly and stop when you feel resistance.
For automatics you don’t wear daily, consider a watch winder—they keep your piece moving and prevent oils from pooling.
5.
Service It Don’t Wait for a Problem
Even the most rugged watches need TLC from the pros.
General rule: Service mechanical watches every 3–5 years.
This includes cleaning the movement, reapplying lubricants, checking seals, and pressure testing.
Skipping servicing can shorten your watch’s life drastically.
6.
Store It Right
Keep your watch in a cool, dry place away from direct sunlight.
Use a watch box or case with cushioned compartments.
If you own multiple watches, rotate them to reduce wear on any single piece.
7.
Use with Respect
Even tool watches have limits. Avoid:
Showering or hot tubs (steam = silent killer).
Extreme sports unless your watch is built for it.
DIY fixes because YouTube tutorials can’t replace skilled technicians.
Final Word: Let Time Be Kind
Watches are more than accessories they’re mechanical marvels, legacy pieces, and sometimes even investments. A little attention goes a long way. Whether it’s a vintage Rolex or a modern TAG Heuer, treat it with respect and it’ll reward you with decades of precision and style.
Got a watch that needs professional servicing or a refresh? Give us a shout we’re here to keep your time ticking beautifully.
A Gentleman’s Guide to Watch Etiquette
A practical guide to watch etiquette, covering how to wear, choose, and match a watch correctly for every occasion.
A fine watch does more than tell time it speaks volumes about its wearer. From boardrooms to dinner dates, your timepiece can enhance your presence or undermine it depending on how you wear it. Here’s a modern gentleman’s guide to watch etiquette: how to wear it, when to wear it, and how not to come across like you’re trying too hard.
1. Match the Watch to the Occasion
Like shoes or cologne, the right watch depends on where you’re going.
Formal Events: Go with a sleek dress watch thin case, leather strap, minimal dial. Think understated elegance.
Business Settings: Chronographs and steel watches are fair game, but keep it classy.
Casual Outings: Dive watches, field watches, or anything with a NATO strap are perfect.
Sports & Outdoors: Stick to digital or rubber-strap watches your Rolex doesn’t need a jog.
🚫 Avoid: Wearing a chunky diver to a black-tie wedding. Unless James Bond invited you personally.
2. Wear It on the Correct Wrist
Traditionally, watches are worn on the non-dominant wrist left for right-handers, and vice versa.
Why? It keeps the crown accessible and avoids damage from overuse or impact.
But hey, rules are guidelines. If it feels better on the other wrist, go for it but be intentional, not random.
3. Size Matters (Seriously)
Wearing a dinner-plate-sized watch on a slim wrist is like turning up to brunch in ski boots.
Ideal diameter is 38mm to 42mm for most wrists.
The lugs should not overhang your wrist.
The strap should hug not strangle your wrist.
✅ Pro Tip: When in doubt, lean toward smaller. Timeless > oversized.
4. Don’t Flash It Subtle Flex Only
A true gentleman never brags about his watch. If someone notices and compliments it, great. But avoid:
Casually dropping the brand into conversation.
Holding your glass just a little too high so everyone sees it.
Taking watch selfies at the dinner table.
Let the watch speak, quietly.
5. Keep It in Shape
A scratched, fogged, or poorly kept watch tells people you don’t respect what you wear.
Regularly clean your watch.
Service it on schedule.
Don’t wear it to bed, in the shower, or when chopping wood (unless it’s G-Shock time).
6. Respect the Strap Game
Changing your strap can transform a watch but don’t go overboard.
Leather = formal.
Steel = versatile.
Rubber/NATO = casual/sporty.
Switching straps is fine, but treat it like tailoring do it with purpose and style.
7. Don’t Double Up on Timepieces
Wearing a smart watch and a mechanical watch? That’s like wearing two pairs of shoes. Choose one.
If you need fitness tracking, go digital. If you’re going for elegance, go analog. Mixing both is confusing… for everyone.
Final Word: Timeless Style Is Effortless
Wearing a watch isn’t just about keeping time it’s about keeping style. A well-chosen timepiece signals taste, awareness, and self-respect. So wear yours like you mean it with confidence, class, and just enough mystery.

How to Change a Watch Battery Safely at Home
A step-by-step guide explaining how watch batteries are changed, what to watch out for, and when it’s best left to a professional.
Changing a watch battery might seem intimidating, but with a little patience and the right tools, it's a simple task you can do at home. Whether your watch has stopped ticking or is showing signs of a dying battery (slow movement, fading display), this guide from JF Jewellers walks you through the process step by step.
⚠️ Note: If your watch is water-resistant, high-end, or sentimental, we always recommend professional servicing to avoid damage.
Tools You’ll Need:
Watch case opener (knife or case wrench, depending on case type)
Non-metal tweezers
Precision screwdriver set
Soft cloth or matt
Replacement battery (correct size for your watch)
Optional: Watch holder or case clamp
Step-by-Step Guide:
1. Prepare Your Workspace
Find a clean, well-lit space. Lay down a soft cloth to prevent scratches to your watch.
2. Open the Watch Case
Watches typically have two types of case backs:
Snap-off case: Use a case knife or thin blade to gently pry the back open at the small notch.
Screw-back case: Use a case wrench or rubber ball to unscrew it counterclockwise.
Be gentle! Excess force can scratch or damage the case.
3. Locate and Remove the Old Battery
Once the case is open, you’ll see the battery held in place by a clip or arm.
Use a plastic tool or non-metal tweezers to carefully lift the battery out.
Take note of the battery’s code (e.g., SR626SW, CR2016) so you can buy the correct replacement.
4. Insert the New Battery
Slide the new battery in using plastic tweezers to avoid static damage.
Ensure it's properly seated and the clips are secure.
If your watch doesn’t start ticking immediately, give it a few seconds or gently tap the case.
5. Test the Watch
Before sealing it back up, check if the hands are moving or digital display is working.
6. Close the Case Back
For snap-off cases, press down firmly with your thumbs or a case press.
For screw-back cases, re-tighten gently with a wrench or your palm using a rubber ball.
Ensure the back is secure to maintain dust and water resistance.
Tips to Keep in Mind:
Don't touch the new battery with bare hands – oil and moisture can reduce battery life.
Use the correct battery type – always match the replacement to your old battery.
Change batteries every 1–2 years to avoid leakage and corrosion.
When to Visit JF Jewellers Instead
Some watches like luxury timepieces, water-resistant models, or those with delicate movements should always be handled by a professional. At JF Jewellers, we offer fast, affordable battery replacement with:
Original-grade batteries

Quartz vs Automatic Watches: Which One Should You Choose?
When it comes to choosing a new watch, one of the first decisions you’ll face is whether to go for a quartz or an automatic movement. Both have unique qualities, loyal followings, and different advantages depending on your lifestyle, preferences, and budget. In this article, we’ll break down the key differences and help you decide which is the right choice for you.
What Is a Quartz Watch?
A quartz watch is powered by a battery that sends an electrical current through a tiny quartz crystal. This causes the crystal to vibrate precisely 32,768 times per second. These vibrations are measured and converted into a consistent pulse that powers the motor and moves the watch hands.
🔧 Key Features of Quartz Watches:
Highly accurate: Usually lose/gain only a few seconds per month
Low maintenance: Battery replacement every 1–2 years
Affordable: Generally less expensive to produce and buy
Lightweight: Fewer mechanical parts make them thinner and lighter
No winding required
Ideal for:
Anyone who wants a reliable, low-maintenance, and budget-friendly watch they can wear daily without worry.
What Is an Automatic Watch?
An automatic (self-winding) watch is powered by a mechanical movement. It contains a rotor that winds the mainspring as your wrist moves throughout the day. No batteries required just motion.
⚙️ Key Features of Automatic Watches:
Mechanical craftsmanship: Built with intricate gears and components
Winding mechanism: Powered by movement or manual winding
Smooth sweep second hand: Unlike quartz’s “tick-tick,” automatics have a smoother hand motion
Heirloom value: Appreciated by collectors for artistry and legacy
Ideal for:
Those who appreciate traditional watchmaking, and enjoy the feel and aesthetic of a finely tuned timepiece.
Which One Is Right for You?
At JF Jewellers, we believe the choice between quartz and automatic comes down to how you use your watch and what you value most.
Choose quartz if you want something practical, reliable, and easy to maintain perfect for daily wear.
Choose automatic if you love craftsmanship, history, and wearing a timepiece that tells more than just the time.
We stock a wide selection of both quartz and automatic watches from budget-friendly pieces to luxury brands. Whether you’re a first-time buyer or a seasoned collector, our team is here to help you find your perfect match.

Automatic vs. Chronograph Watches: What's the Difference?
A clear comparison of quartz and automatic watches, explaining how they work, their pros and cons, and which suits different lifestyles.
When shopping for a new timepiece, you’ve likely come across terms like “automatic” and “chronograph.” Though they may sound similar or even interchangeable, they refer to two completely different watch features. At JF Jewellers, we believe understanding these terms helps you make the right choice based on both style and function.
What Is an Automatic Watch?
An automatic watch is a self-winding mechanical watch. It doesn't need a battery because it winds itself through the natural motion of your wrist. Inside, a rotor spins and transfers energy to a mainspring, which powers the watch.
🔧 Key Characteristics:
Powered by motion
No battery required
Smooth, sweeping second hand
Often prized for their craftsmanship and classic aesthetics
Automatic watches can come with a wide range of complications (features), but the term “automatic” strictly refers to how the watch is powered not what it does.
What Is a Chronograph Watch?
A chronograph is a watch with a built-in stopwatch function. It usually has additional sub-dials and pushers (buttons) on the side that control the start, stop, and reset functions.
Chronograph watches can be quartz, mechanical, or automatic, meaning “chronograph” refers to the functionality, not the movement type.
⏱️ Key Characteristics:
Multiple sub-dials (e.g., 30-minute, 12-hour counters)
Pushers on the case for stopwatch control
Can time events while still displaying the current time
Sporty, functional appearance — often used in racing, aviation, and diving
Can a Watch Be Both?
Absolutely many watches are both automatic chronographs. These combine the best of both worlds: a self-winding movement and stopwatch functionality. They tend to be larger, more complex, and often more expensive due to the engineering involved.
Which Should You Choose?
Choose an automatic watch if you appreciate traditional watchmaking, a minimalist design, and prefer a battery-free experience.
Choose a chronograph watch if you need additional functionality (like timing events) or prefer a bolder, sportier style.
Whether you're drawn to the elegance of an automatic or the utility of a chronograph, JF Jewellers has a curated selection to match your needs.

The Ultimate Guide to Choosing the Perfect Engagement Ring
A complete guide to choosing the perfect engagement ring, including budgeting, the 4Cs, diamond shapes, metals, and personalisation tips.
So, You’re Ready to Propose — Congratulations!
Whether you’re deeply in love, fully committed, or simply ready to make it official, choosing the perfect engagement ring is a major milestone. And yes while it might feel a little overwhelming (especially if you’ve been relying on guesswork), don’t worry. You’re in the right place.
Here’s a clear, step-by-step guide to help you navigate the process with confidence, style, and financial sanity.
1. Set a Budget (and Stick to It)
Forget outdated advice like “three months’ salary.” The right budget is one that fits your lifestyle and financial goals. An engagement ring should symbolise love and commitment not cause financial stress.
💡 Pro Tip: Remember to factor in not just the diamond (or alternative stone), but also the setting, resizing costs, insurance, and maybe even a celebratory dinner afterward.
2. Understand the 4Cs of Diamonds
Before you start shopping, get familiar with the four characteristics used to evaluate diamonds:
Cut – This affects how well the diamond reflects light (aka its sparkle). It’s the most important of the 4Cs.
Colour – Rated from D (colourless) to Z (light yellow or brown). Near-colourless (G–J) diamonds offer great value.
Clarity – Refers to imperfections. Most are microscopic and don’t impact visual beauty.
Carat – The weight of the diamond. Bigger doesn’t always mean better — a well-cut diamond with lower carat weight can look larger and more brilliant.
💎 Bottom Line: Prioritise cut and overall appearance over carat size alone.
3. Choose a Diamond Shape That Reflects Their Style
Each diamond shape brings its own character:
Round – Classic and timeless
Oval or Pear – Elegant with a unique twist
Princess or Cushion – Bold and glamorous
Emerald or Asscher – Sophisticated with vintage appeal
Look at the jewellery they already wear. Are they into minimalism, vintage pieces, or bold designs? Their style will guide you toward the perfect shape.
4. Select the Right Metal for the Setting
The ring’s metal is a big part of its overall look. Popular choices include:
Yellow Gold – Traditional, warm, and timeless
White Gold or Platinum – Sleek and modern
Rose Gold – Romantic and trendy
🔎 Note: Platinum is hypoallergenic and more durable but tends to cost more. Try to match the ring’s tone to the jewellery they already wear most often.
5. Consider Alternative Stones
Diamonds are traditional, but they’re not the only option. If your partner prefers something unique, consider:
Sapphires – Come in many colours
Emeralds – Bold and vibrant
Moissanite – Ethical, affordable, and extremely sparkly
Lab-Grown Diamonds – Eco-friendly and identical in appearance to mined diamonds
Just make sure the stone you choose is durable enough for everyday wear.
6. Add a Personal Touch
Personalisation makes the ring even more meaningful. You could:
Engrave a special message, initials, or date inside the band
Custom-design the ring to include a unique element or hidden detail
These thoughtful extras turn a beautiful ring into a one-of-a-kind symbol of your story together.
Final Thoughts
An engagement ring is so much more than a piece of jewellery it’s a lasting symbol of love and commitment. Choose with care, stay true to your partner’s style, and don’t feel pressured to overspend. With thoughtful planning, you’ll find the perfect ring that captures your story and sets the tone for a beautiful future together.
