FAQ Frequently Asked Questions
What is the difference between the Automatic, Quartz and Meca-Quartz movements?
Automatic movements are powered by the motion of your wrist and prized for their craftsmanship. Quartz movements run on a battery for maximum precision and low maintenance. Meca-Quartz pairs a quartz base with a mechanical chronograph module, combining accuracy with a mechanical feel.
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.
How can I find out the lug width on my UNIMATIC watch
All UNIMATIC watches have a lug width of 22mm.
What is the size of the strap?
All our straps are designed to fit our watches, which use 22 mm wide straps.
They are available in one size only.
To check whether the strap will fit your wrist, please refer to the size information in the product page.
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 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.
What is a reference number?
A reference number is an alphanumeric code associated with each watch model (e.g., U1S-T-MP).
You can find the reference number in the documents provided at the time of purchase, such as the International Warranty certificate, or on the case-back of your watch.
Does the stainless steel bracelet fit my watch?
The UNIMATIC UBR-TLQ18 solid stainless steel bracelet is compatible with almost all the UNIMATIC lineup. Above is a chart to help you choose the correct end-link variation for your watch. Please note that the bracelet is available in two different finishes: Brushed and Sandblasted. While a bracelet may be mechanically compatible with your watch in terms of fit and attachment, it may not match the watch aesthetically if the finish is different.
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.
