Timelessly elegant
UNIMATIC’s classic diver design is a modern reinterpretation of timeless tool-watch aesthetics — stripped down to essentials with bold legibility, clean geometry, and a utilitarian edge. Characterized by its oversized crown, stark dial with luminous markers, and unidirectional bezel, it channels vintage military influences while embracing contemporary minimalism.
BUILT to perform
Built in Italy with a focus on durability and purpose, a UNIMATIC is more than a watch — it's a refined tool designed for reliability in any environment. With 300m water resistance, automatic movement, and a minimalist design, it’s made to perform, built to last.
high legibility classic dial
The UNIMATIC high legibility classic dial is a study in purposeful clarity. Featuring big geometric hour markers, a clean minute track, and a stark contrast between dial and lume, it’s designed for instant readability in any condition.
adapts to your style
All UNIMATIC watches feature a universal lugs size width of 22mm, allowing easy switching between styles and materials like leather, nylon, rubber, or metal to suit any occasion and making customization simple and seamless.


The Modello Tre UNIMATIC U3 CLASSIC UC3 Italian-made chrono-diver watch features a two-eyes black matte dial with Super-LumiNova® C3 pale green markers, a lumed dot on the minimal black aluminium diver bezel, and off-white second rail and dial trims. Time is displayed with matching phantom ladder hands and a black reverse lollipop seconds hand with an off-white tip.
The 2.5 mm double-domed anti-reflective sapphire crystal ensures perfect visibility under any lighting. The brushed 316L stainless steel case, screw-in caseback, 8 mm crown, and 5.5 mm screw-in pushers, combined with premium gaskets, provide individually tested 300M water resistance (30 ATM ≈ 1000ft).
Powered by the VK64 mecha-quartz movement, it offers 1/5 second timing, 60-minute counter, and up to 3 years battery life. The watch comes on a black heavy-duty NATO nylon strap with brushed stainless steel hardware signed UNIMATIC.

Frequently asked questions
We choose each movement to match the unique character of the watch. Our Automatic models - typically powered by the NH35A or the SW200-1 - are driven by the natural motion of your wrist, honoring the heritage of traditional watchmaking. Meanwhile, our Toolwatch Series features high-precision, battery-powered calibers paired with our proprietary protection system, designed to withstand impacts and drops. For our chronograph models, we selected the VK31 movement: the current market offers very few automatic chronograph movements that combine reliability with accessible pricing, making this caliber the most dependable and practical choice for our purpose-built watches. A meca-quartz movement is a hybrid movement that combines quartz timekeeping with mechanical chronograph components.
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.
