Description

For men who want a mechanical watch that shows how it works, the ONOLA ON3840 puts the automatic movement on display. The skeleton dial and transparent case back let you see the gears and rotor in motion, turning a daily accessory into a small piece of engineering.

Built for Daily Wear

The 44mm alloy case and mineral glass are specified to handle everyday contact with desks, door handles, and bags. The stainless steel band and butterfly double-press clasp keep the watch fixed on the wrist during commutes and office hours.

Water Resistance for Real Life

Rated at 30M, the watch is designed to withstand splashes from hand washing and rain. It is not intended for swimming or diving. This rating covers the accidental exposure that happens in normal daily routines.

Automatic Movement, No Battery

The mechanical movement winds itself as you move, so there is no battery to replace. The transparent case back shows the rotor spinning with your arm's motion, and the crown at the side lets you set the time when needed.

Color Options for Different Tastes

Choose from rose-black with rose steel band, rose-black with black steel band, rose-blue, silver-white, silver-blue, or silver-green. Each version keeps the same 44mm case and 15mm thickness, so the fit stays consistent across finishes.
