What is an Automatic Watch?
What is an Automatic Watch?
An automatic watch is powered by movement, not a battery. As you wear it, your wrist naturally winds the movement to keep it running.
If left unworn for around 40 hours, it may stop - simply wear it again or gently wind the crown to restart it.
Refined Everyday Comfort
Crafted from soft genuine leather, this strap brings timeless style to any 20mm watch. Whether you’re heading to the office or out for dinner, the Leather Strap Kit delivers that sleek, polished look — no metal bracelet required. Flexible from day one, it molds comfortably to your wrist with wear.
Easy DIY Install – Tools Included
Each kit comes with everything you need to swap straps at home. You’ll receive a spring bar tool and spare bars, so even beginners can install it in minutes — no watchmaker needed. Quick change, clean look, all in the box.
Polished Deployment Clasp
The included butterfly-style deployment clasp offers a premium feel and added convenience. It reduces wear on the leather and gives a cleaner look compared to traditional buckles. Easy to operate, secure on the wrist, and subtle in design.
Premium Components

Automatic, self-winding, 40+ hour power reserve, trusted in the watch industry for its accuracy.

3 ATM water resistance, perfect for daily wear, rain and water splashes.

Fitted with sapphire crystal, clear and scratch resistant.
