A 40mm bold yellow chronograph built for men who know exactly what they want. Japanese VK63 meca-quartz, sapphire crystal, gold accents.
The yellow dial accents give the watch its motorsport-inspired identity, while the dark case and strap keep the overall look refined and easy to wear.
Quartz accuracy. Mechanical chronograph snap. Zero drift, zero service anxiety. Replace a battery every 3 years and you're done.
The same scratch-resistant glass used in watches costing several times more. In daily use it stays clean-faced for years.
Large enough to read easily. Balanced enough to wear under a shirt cuff. The sweet spot for most men.
Crown, pushers and bezel markings all in warm gold-tone. Pairs with the yellow dial without competing with it.

Press the upper pusher (2 o'clock) to start timing. Press it again to stop. Press the lower pusher (4 o'clock) to snap all hands back to 12 — you'll feel and hear the VK63 mechanism reset. The small running seconds subdial at 12 ticks continuously while the watch is running.
The crown is screw-down for extra moisture protection. Before setting the time: unscrew the crown counterclockwise until it releases. After adjusting: press it inward and screw it clockwise until snug. Always screw it back down before wearing.
No — and that is a good thing. The VK63 meca-quartz gives you mechanical chronograph action with quartz accuracy. No winding, no drift, no service appointments. A battery lasts around 3 years. Swap it and keep going.
