Questions before ordering?
Our team can help with product, delivery and after-sales questions.
The details that matter.
Clear answers before you order.
How does the chronograph work?
The upper pusher starts and stops the chronograph. The lower pusher resets it after the chronograph has been stopped. The small seconds subdial shows the normal running seconds.
What movement does this watch use?
It uses a Japanese VK63 meca-quartz movement, combining the accuracy of quartz with the mechanical feel of a traditional chronograph. The chronograph (stopwatch function) is operated using the pushers on the side of the case.
Can I return it?
Orders can be returned within 30 days in accordance with the return policy.
How long does delivery take?
Delivery time depends on destination and order processing. Estimated delivery is typically 5–8 business days.
BUILT FOR
MEN WHO KNOW
WHAT THEY WANT.
The watch that gets noticed without asking to be.
There is a certain kind of watch that earns comments not because it is flashy, but because it is unmistakably right. The Yellow Racing Chronograph is that watch.
The yellow dial does not scream. It simply refuses to disappear. On a dark wrist, on a casual sleeve, it catches light and holds attention — the way a well-chosen car colour does in a car park full of grey and silver.
Wear it to a weekend car meet and someone will ask. Wear it to dinner and someone will notice. Wear it to the office and say nothing. That is enough.
Dark denim, a white shirt or an olive field jacket. The yellow dial handles the talking — everything else should stay quiet.
Why the VK63 is the right choice for daily wear.
At 45, you have probably owned a few watches. You know the drill: automatics are romantic but fussy. Cheap quartz is reliable but forgettable. The VK63 sits in a more interesting place.
It is a meca-quartz movement — Japanese engineering that combines quartz accuracy with a genuine mechanical chronograph action. When you press the top pusher, the sweep hand snaps away. When you reset, it snaps back. Instantly. Every time.
Battery lasts roughly three years. No service intervals. No magnetism anxiety. No setting it every morning. Just put it on and get on with your day.
The VK63 was developed for professional use. It is not a budget movement. It is an engineering decision.
The bezel is not decoration. Here is how to use it.
The tachymetre scale on the outer bezel is one of the most misunderstood features on a chronograph. Most men wear it. Few actually use it.
Measuring speed: Start the chronograph as a vehicle passes the start of a measured distance. Stop it at the finish. Read where the sweep hand points on the tachymetre ring — that is the speed in km/h or mph.
Measuring rate: Start when a task begins, stop when it ends. The tachymetre tells you how many completions are possible per hour. Analogue, precise, genuinely useful.
Sweep hand lands at 120 after timing one kilometre → the vehicle was travelling at 120 km/h. Simple, satisfying, entirely analogue.
What to expect in the first 30 days.
Day one: it will look bigger on the wrist than in photographs. The yellow dial takes up space. Give it a week. By day seven it will feel like it was always there.
The sapphire crystal is genuinely scratch resistant in daily use. Do not test it deliberately, but do not worry about it either. In normal wear it will stay clean-faced for years.
The rubber strap softens slightly with wear — this improves fit. Any standard 20mm strap fits directly. Leather, NATO, or a different rubber if you prefer.
The crystal will still be clean. The movement will still be accurate. The yellow dial will still get a second look. Some watches you stop noticing. This is not one of them.
Does a 40mm watch actually work on your wrist?
The Yellow Racing Chronograph measures 40mm across the case and 47.5mm lug to lug. That is the sweet spot that most men at 45 have landed on — large enough to read comfortably, proportional enough not to look like a prop.
Here is how 40mm typically wears by wrist circumference:
| Wrist size | How 40mm wears | Verdict |
|---|---|---|
| Under 6 in / 15.2 cm | Large, possibly overhanging the wrist | Try in person first |
| 6–6.5 in / 15.2–16.5 cm | Strong presence — commands attention | Works well |
| 6.5–7 in / 16.5–17.8 cm | Modern and balanced — ideal proportions | Ideal fit |
| 7–7.5 in / 17.8–19.1 cm | Proportional and noticeable | Excellent fit |
| Over 7.5 in / 19.1 cm | Usually balanced — sits naturally | Natural fit |
The most common male wrist in the 45–60 age range is 6.5–7.5 inches. If that is you, the 40mm case will sit exactly as it should — present without being large, refined without being small.
The lug-to-lug measurement of 47.5mm also matters: this is the distance the case spans across your wrist. A case that does not overhang the wrist edges will always look more considered.
Wrap a soft tape measure or a strip of paper around your wrist just above the wrist bone. That number in inches or centimetres is your wrist circumference. Use the table above to find your fit.
