Description
The UNIMATIC Modello Quattro UT4-JDM is a Made in Italy military quartz watch created exclusively for the Japanese Domestic Market (JDM). Designed for durability and precision, it features a matte grainé gunmetal dial enhanced with Super-LumiNova® GL Old Radium markers, a cool gray open second rail, and refined dial trims. Time is displayed with phantom ladder hands and a reverse lollipop seconds hand accented by a cool gray tip, reflecting UNIMATIC’s signature minimalist design.
Protected by a flat anti-reflective sapphire crystal, the UT4-JDM ensures exceptional legibility under any lighting conditions. Its matte gunmetal PVD-coated 316L stainless steel case, screw-in 2mm thick caseback, 8mm crown, and premium gaskets deliver professional-grade reliability and 300m (30 ATM / 1000ft) water resistance, each unit individually tested for performance.
Powered by the VH31 Japanese quartz movement, the UT4-JDM achieves precise timing with a smooth sweeping seconds hand. The movement is housed within a Made-in-Italy TPU 360° anti-shock protection system, ensuring superior impact resistance — a hallmark of UNIMATIC’s toolwatch engineering.
The watch is completed with a dark olive nylon two-piece keeper strap, fitted with matte gunmetal PVD-coated stainless steel sandblasted hardware signed UNIMATIC, perfectly integrated into its 22mm lugs.
On the caseback, a Japanese Domestic Market screw-down engraving underscores its exclusivity. The UNIMATIC Modello Quattro UT4-JDM comes with a 24-month worldwide warranty, reaffirming the brand’s commitment to quality and precision craftsmanship.

Focus
JAPAN DOMESTIC MARKET
The first UNIMATIC created exclusively for Japan, it unites Italian design discipline with Japanese precision. Featuring a specially developed caseback for all domestic market releases, it embodies both heritage and innovation in this bold new chapter of UNIMATIC’s 10-year journey.
PVD COATING
Physical Vapor Deposition is a thin, exceptionally durable coating that significantly enhances surface strength and extends the lifespan of materials. It also provides outstanding corrosion and wear resistance, ensuring a long-lasting, high-quality finish even under demanding conditions.
SHOCK RESISTANT
The 360° protection system is designed in-house and made in Italy to the highest standards. It is realised in a special blend of thermoplastic polyurethane (TPU) material. Its custom construction, composed of a 360° protection shell that perfectly holds the movement and a dial top protective ring, allows the watch to withstand extreme environmental stress while still keeping it super light.
