❓ FAQ
How does an automatic movement work?
It winds itself with the natural movement of your wrist: an oscillating rotor keeps the mainspring charged. No battery needed. If you don't wear it for a day or two, just give the crown a few turns to restart it.
Can I wear this watch in the rain?
Yes, its 3 ATM water resistance protects it from splashes and rain. We do not recommend swimming, showering or diving with it.
Is this watch a good gift?
Absolutely. It's an ideal gift for a birthday, a celebration or any special occasion. Several colors are available to suit his style.
