Modello Quattro ref. UT4-AA2 is the Made in Italy quartz watch. It features a Verde Brinzio diver dial with a yellow Automobili Amos logo, markers in Super-LumiNova® C3 pale green lume and silver open second rail and dial trims.

Time is indicated thanks to the matching phantom ladder hands set and the reverse lollipop second hand with yellow tip.

The 2.8 mm thick flat sapphire crystal is treated with an anti-reflective coating.

The solid 316 sandblasted gunmetal coated stainless steel case, the screwed-in 2.2 mm thick caseback, the 8 mm diameter crown and the high quality gaskets set provide a water resistance tested individually to 30 atm=300m=1000ft.

Timing accuracy is guaranteed by the Quartz Seiko VH31 movement with a sweeping second hand, fitted with a yellow TPU anti-shock. It comes on a verde Brinzio TPU two-piece strap with stainless steel sandblasted gunmetal coated hardware signed Unimatic, that fits in the 22 mm drilled lugs.

The caseback features the Unimatic x Automobili Amos engraving and the individual progressive number. The watch is covered by a 24 months worldwide warranty and is part of a unique edition of 150 pieces.

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.

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.
