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?
Press the upper pusher at 2 o'clock to start timing. Press it again to stop. Press the lower pusher at 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.
What is a screw-down crown and how do I use it?
The crown is the small knob on the right side of the case. It screws down for extra moisture protection. Before setting the time: unscrew counterclockwise until it releases. After adjusting: press inward and screw clockwise until snug. Always screw it back down before wearing — especially near water.
Is this an automatic watch?
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.
Can I return it?
Yes — 30-day returns, full refund, no questions asked. Plus the 180-day warranty covers any fault worldwide. Email support@zjani-mods.com with your order number and we will take care of it.
