A Classic, Reimagined.
Some watch designs never lose their appeal. The WD1863 captures the purposeful character of a traditional multi-register chronograph while introducing contemporary materials and carefully considered finishing.
From its contrasting subdials to its sculpted case and detailed hands, each element contributes to a watch that feels familiar without being ordinary.
Designed to Wear. Not Just Admire.
A chronograph should look substantial without feeling unnecessarily oversized. The WD1863 balances a 39mm bezel with a 41mm mid-case and a compact 46mm lug-to-lug measurement.
At approximately 12.9mm thick, including the domed crystal, it maintains a layered profile and wearable proportions.


Depth in Every Detail.
The domed sapphire crystal is a defining visual feature of the WD1863. Its curved profile adds depth to the dial and reinforces the vintage-inspired aesthetic.
An anti-reflective coating helps legibility, while sapphire provides strong resistance to everyday scratches.
Quartz Reliability. Chronograph Character.
At the heart of the WD1863 is the Japanese VK63 meca-quartz chronograph movement.
It combines battery-powered quartz timekeeping with a mechanical-style chronograph operation, including a sweeping central chronograph seconds hand and crisp reset action.


One Collection. Many Personalities.
Choose a restrained black or white dial, a high-contrast panda configuration, a racing-inspired design or a more colorful interpretation.
Hand shapes, luminous material, subdial finishes and bezel colors vary between versions. Please review the selected variant carefully.
Thoughtful Details. Everyday Comfort.
The stainless steel bracelet complements the WD1863's classic proportions.
Depending on the configuration, bracelet-link construction and clasp systems may differ, including five-hole micro-adjustment and on-the-fly adjustment options. Confirm the specifications of your chosen version.


Built for More Than Special Occasions.
With a 316L stainless steel case, screw-down crown, sapphire crystal and 100m water-resistance rating, the WD1863 combines classic chronograph styling with practical everyday specifications.
Do not operate the chronograph pushers underwater.
