FAQ:
Q: Does this watch require a battery?
A. : No, it is a fully automatic mechanical watch that wring naturally with a weighted rotor driven by my daily wrist.
Q: Why choose stainless steel strap instead of leather strap?
A. : Unlike leather straps that can retain moisture and degrade over time as a result of daily sweat during summer or intense schedules, our 316L stainless steel strap is highly resistant to corrosion, sturdy and retains its excellent shine in all environments.
Q. : Can I wear this watch while swimming or showering?
A. : The watch has a 5 bar water resistance which can easily handle daily splashes, rain and hand washing. However, it is not recommended to swim, diving or hot shower, as sudden changes in temperature can affect the internal waterproof seals.
Q: How to care for the mechanical watch?
A. : To maintain accuracy, avoid exposing your watch to repeated shocks, extreme magnetic fields, or strong arm movements (such as playing tennis or hammering) that can load the internal balance wheel.
