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.

What is a reference number?
A reference number is an alphanumeric code associated with each watch model (e.g., U1S-T-MP).
