FAQ Frequently Asked Questions

What is an automatic watch?

The UNIMATIC automatic watch is a self-winding mechanical timepiece powered not by a battery, but by the natural kinetic energy generated from the wearer’s arm movements. Automatic watches are more sensitive to factors like temperature fluctuations, impacts, and how they are worn. Consequently, they may not run as precisely as quartz watches, and any timekeeping variations depend on the specific movement type. Based on experience, new mechanical watches may initially show slight time inaccuracies, which generally self-regulate over time.

Are UNIMATIC watches truly professional diver tools?

Yes. Every diver is water resistant to 300m, individually pressure-tested, and built around a screw-down caseback and crown with a mono-directional safety bezel, fully rated for professional diving.

Why is every UNIMATIC watch individually numbered?

Each piece is produced in a strictly limited edition and numbered by hand on the caseback, guaranteeing its authenticity and its place within the series.

How durable are UNIMATIC watches for daily wear?

The 316L stainless steel case, double-domed sapphire crystal with anti-reflective coating and 360° protection system are engineered to take daily knocks in stride, from the desk to the water.

What kind of lume is used for low-light visibility?

Hands and indices are treated (unless stated) with Super-LumiNova® colours picked to match the design details, delivering a strong, long-lasting glow for clear legibility in low-light and underwater conditions. It is not radioactive and requires exposure to light (natural or artificial) to charge.

Are UNIMATIC watches water resistant?

All UNIMATIC cases are engineered to provide exceptional water resistance. Every UNIMATIC watch is individually tested to ensure a minimum water resistance of 300m (30 ATM), while selected on case modello 1 featuring our enhanced case construction are tested to withstand 600m (60 ATM). Before exposing your watch to water, always make sure the crown and, where applicable, the pushers are fully screwed down and securely tightened. Never operate the crown or pushers while the watch is underwater. After use in seawater, rinse the watch thoroughly with fresh water and dry it completely.Please refer to your specific model's technical specifications to confirm its certified water resistance rating.
