Are they original?

We use genuine Seiko movements to create unique watches inspired by top designs.

How does an automatic movement work?

Our automatic movements features a 41-hour power reserve and is powered by wrist motion through a self-winding rotor. It can also be manually wound via the crown and requires no battery. This blend of convenience and precision ensures your watch stays running with regular wear or by manual winding when needed.

Should I take a 36mm or 40mm watch?

If you are not sure about what case diameter size you should order, we recommend to size your wrist with a rope.

Under 17,5cm (6.9"): go with 36mm

Above 19,5cm (7.7"): go with 40mm

In between both sizes would suit you well, its a personal preference if you like a bigger watch face or a smaller one.
