Modello Quattro UT4-U-TI Ultratool Toolwatch - Time Only

We choose each movement to match the unique character of the watch. Our Time-Only Automatic models are powered by the Japanese NH35A or the Swiss SW200-1, driven by the natural motion of your wrist to honor traditional watchmaking. For our GMT series, we rely on the Japanese NH34 or the Swiss ETA 2893, allowing for seamless tracking of multiple time zones.

Meanwhile, our Toolwatch Series features high-precision, battery-powered calibers paired with our proprietary protection system, designed to withstand extreme impacts. This includes the Japanese VH31 ‘Sweep Second’ for our time-only models and the Swiss Ronda 515.24H for our GMTs.

For our chronographs, we select the caliber that best fits the watch’s mission: the premium Swiss Automatic SW510, or the Japanese VK64 Meca-quartz. The latter offers a hybrid ‘best of both worlds’ solution, combining quartz accuracy with the tactile, mechanical feel of a traditional chronograph.

Absolutely. Every UNIMATIC diver is water-resistant to 300 m (1000 ft) and individually tested to ensure perfect seal integrity. Each piece features a heavy-duty screw-down caseback, a screw-down crown with high-quality gaskets, and a 120-click mono-directional bezel, meeting and often exceeding professional diving standards.

The only precaution required before entering the water is to ensure the crown is fully screwed down, guaranteeing the watch maintains its complete water-resistant performance.

Whether it belongs to a limited edition or our permanent line, every UNIMATIC watch is individually numbered on the caseback. This unique ID serves as a mark of authenticity and craftsmanship, ensuring that your specific timepiece is one-of-a-kind. For limited runs, it marks its place in a finite series; for our core collection, it highlights our commitment to quality limiting it to a yearly production batch. Exclusivity is a pillar of our design philosophy.

They are built as modern tough tools. We use 316L surgical-grade stainless steel for the cases and double-domed, anti-reflective Sapphire crystals, which are virtually scratch-proof. Whether you are in a boardroom or the North Sea, the watch is designed to withstand impact and harsh environments.

We use high-grade Super-LumiNova (typically C3 or BGW9) on our dials and hands. The luminous material charges from exposure to any light source and then releases a strong, long-lasting glow, ensuring reliable visibility whenever you need it.
