FAQ Frequently Asked Questions
Why do you call it the UNIMATIC Toolwatch?
The UNIMATIC Toolwatch collection is built around our proprietary 360° Protection System, engineered to maximize durability and reliability in demanding conditions; The collection features exclusively quartz-powered watches;
The system combines a TPU protective gasket positioned above the dial with a TPU movement holder. Together, these components absorb shocks and protect the movement and hands from impacts, helping the watch remain fully functional after drops, knocks, and vibrations.
To validate its performance, the entire protection system has been independently tested and certified to MIL-STD-810H, the U.S. military standard for evaluating the durability and ruggedness of technical equipment.
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.
What is a bezel used for?
Dive / Elapsed Time Bezel:
Marked from 0 to 60 minutes, this bezel rotates only counter-clockwise. Align the triangle (0 marker) with the current position of the minute hand to track the elapsed time at a glance.
Countdown Bezel: Marked in reverse, from 60 down to 0, this bezel is designed for timing a set interval. Rotate it so the desired number of minutes (for example, 15) lines up with the minute hand. When the minute hand reaches the 0 marker, the countdown is complete.
GMT Bezel: Featuring a 24-hour scale, the GMT bezel rotates in both directions and works together with your watch's GMT hand to display a second time zone. By adjusting the bezel, you can also track a third time zone.
Compass Bezel: Marked with the cardinal directions, the compass bezel can be used for basic navigation. Point the hour hand toward the sun, then use the bezel's directional markings to determine north and south.
