Unimatic Modello Quattro U4S-T-LB: Minimalism With A California Twist

MRSTATELESS NEW RELEASES, UNIMATIC 2026, Diver, Limited Edition, Titanium 0

The Modello Quattro U4S-T-LB introduces a fresh take on Unimatic’s diver-field watch concept, combining robust construction with a distinctive seasonal color palette. Built for versatility, it blends professional-grade specifications with a lightweight and highly wearable design.

A Proven Case, Now in Titanium

The U4S-T-LB retains the familiar proportions of the Modello Quattro, featuring a 40 mm case diameter. However, at 12.70 mm thick, it is slightly slimmer than earlier executions thanks to the adoption of the Sellita SW200-1 automatic movement. One of the most notable upgrades is the use of sandblasted titanium for the case and bezel, significantly reducing the overall weight to just 65 grams. This makes it particularly comfortable for extended wear, especially in warmer conditions.

The case construction remains purpose-driven, with a box-shaped sapphire crystal, a screw-down crown, and a solid titanium caseback. The latter is engraved with a motif inspired by NATO military symbology, reinforcing the watch’s tool-oriented character. Water resistance is rated at 300 meters, placing it firmly within professional dive watch territory.

Reliable Swiss Mechanics

Powering the watch is the Sellita SW200-1, a widely used and proven automatic movement. It operates at 28,800 vibrations per hour (4Hz) and delivers a power reserve of approximately 41 hours. The movement is regulated to an accuracy of +/-12 seconds per day, ensuring dependable performance for everyday use.

California Dial with Contemporary Contrast

One of the defining features of this model is its California dial layout. The matte grey base provides a neutral backdrop, while the hour markers are split between Roman numerals on the upper half and Arabic numerals on the lower half. This distinctive configuration enhances legibility and adds visual interest.

The dial is further characterized by its mint green accents, which outline the hour track and are applied to the Super-LumiNova coating. This lume emits a turquoise glow in low-light conditions and is also present on the hands, including the seconds hand’s lollipop counterbalance. The color choice introduces a vibrant yet balanced contrast against the otherwise monochromatic design.

Built for Active Use

The watch is paired with a matching mint green nylon NATO strap, fitted with sandblasted titanium hardware. This setup not only complements the dial but also reinforces the lightweight and durable nature of the watch. The combination of titanium construction, high water resistance, and secure strap system makes it well-suited for outdoor activities and water-based environments.

Limited Production

The Modello Quattro U4S-T-LB is produced as a limited edition of 300 pieces. It is available directly from Unimatic, with a retail price of € 1,470.
