The UNIMATIC Modello Uno Toolwatch UT1 is a quartz dive-style watch with a 40 mm case, a 120-click countdown bezel and a manufacturer-stated 300 m water-resistance rating. Its defining details include a sweeping-seconds quartz movement, high-contrast dial and integrated TPU protection system. The specifications below are published by UNIMATIC; they are not independent measurements or a personal wear test.
What is the UNIMATIC UT1?
The UT1 is the standard-reference UNIMATIC Modello Uno Toolwatch, distinct from the UT1-GMT and limited UT1 variants. UNIMATIC describes it as a Made-in-Italy quartz dive watch. Its design combines a matte black countdown bezel insert with a black dial, printed Arabic numerals, a white seconds track and orange accents. The phantom ladder hour and minute hands and reverse-lollipop seconds hand—with an orange tip—give the dial its distinctive layout. These are design features, not evidence of superior field performance.
The case is sandblasted 316L stainless steel, with a flat sapphire crystal and inner anti-reflective treatment, screw-down caseback and 8 mm screw-down crown. UNIMATIC also describes an in-house-designed TPU 360-degree protection system. UNIMATIC’s product page and its technical specification sheet provide the manufacturer’s description and specifications.
How big is the UT1 on the wrist?
UNIMATIC’s technical sheet lists a 40 mm case diameter, increasing to 41.5 mm when measured across the bezel, and a 49 mm lug-to-lug length. Thickness is 13.2 mm without the lens and 13.6 mm with it. The watch weighs 80 g without a strap and 95 g with the supplied strap. These are manufacturer-published figures, not independent measurements. The 49 mm lug-to-lug dimension is useful to consider alongside the case diameter when judging whether the watch’s footprint will suit your wrist.

Is the UT1 automatic or quartz?
The UT1 uses a Seiko VH31A quartz movement with two jewels and a sweeping seconds hand. UNIMATIC lists a Seizaiken SR920SW battery, approximately two years of power reserve and stated accuracy of ±15 seconds per month. Those accuracy and reserve figures come from the manufacturer’s technical sheet; no independent accuracy test or battery-life measurement is documented here. The sheet also uses the phrase “MIL-STD-810H, singularly tested for accuracy and water resistance”; that wording should not be read as evidence of independent military certification.
What does the 300 m water-resistance rating mean for this model?
UNIMATIC lists the UT1 at 300 m, approximately 1,000 ft or 30 atm, and says each watch is individually tested to ensure a minimum 300 m (30 ATM) water resistance. The manufacturer also says selected Modello 1 watches with enhanced case construction are tested to withstand 600 m (60 ATM); that higher figure is not the UT1’s stated rating. The available manufacturer materials do not provide a UT1-specific independent test report or the full test procedure, so the rating and testing statements should be understood as UNIMATIC’s claims rather than independent verification.

For context on its testing language, UNIMATIC has published an article titled “UNIMATIC Tool Watches | MIL-STD-810H Certified”. The cited material does not establish that the UT1 is independently certified to a military standard.
What strap fits the UT1?
The watch has 22 mm lugs and is supplied with a black, two-piece quick-release nylon strap with signed sandblasted hardware. A replacement strap with a 22 mm width is a reasonable starting point, but width alone does not establish that its end fitting or connector will work with the watch’s attachment arrangement. Check those details before buying.
