UNILIGHT Modello Quattro UT4-TBB Collab pairs Patriot Blue Cerakote with MIL-STD-810H shock certification and 300m water resistance. GCC collector overview.
Points of Note
- Priced on request, the Modello Quattro UT4-TBB Collab pairs a Patriot Blue Cerakote® powder-coat over a 316L stainless steel case with MIL-STD-810H shock certification — a combination rarely found at this positioning in the tactical diver segment.
- The 360° Protection System, designed in-house and manufactured in Italy from thermoplastic polyurethane (TPU), absorbs drops, knocks, and vibrations while keeping overall weight low.
- Water resistance is rated to 300m (30 ATM), with each case individually pressure-tested before leaving the workshop.
- Three-dimensional hand-applied markers rise above the dial plane and carry Super-LumiNova® pigment, delivering clear legibility in low-light and underwater conditions.
Design & Mechanics
Cerakote® is the coating technology that changes what this watch can ask of its case.
The Patriot Blue Cerakote® finish is applied by powder-coat to the 316L stainless steel case, producing a matte, tactical surface that resists scratches, corrosion, and prolonged wear. This is not a decorative treatment: Cerakote® is specified in military and law-enforcement equipment precisely for its long-term surface integrity under field conditions. On the UT4-TBB, it brings a controlled, monochromatic depth to a case that carries no surplus ornamentation.
Heritage & Lineage
UNIMATIC’s Toolwatch series has, from its earliest references, organised itself around one engineering premise: protection as architecture.
The 360° Protection System debuted as the collection’s founding proposition. A TPU gasket above the dial and a TPU movement holder below work together to absorb shocks that would compromise a conventionally cased quartz movement. The system has been independently certified to MIL-STD-810H, the U.S. military standard for equipment durability. What changes with the UT4-TBB Collab is the surface language: Patriot Blue Cerakote® shifts the aesthetic from industrial grey toward a more directional, collector-oriented palette, without altering the underlying protection architecture.
Why Collectors Care
Individual numbering on the caseback, combined with a handwritten international warranty card, establishes each UT4-TBB as a discrete, verifiable object within the series.
For the Gulf buyer attending Watches and Wonders or sourcing through specialist channels, that traceability carries weight. The double-domed sapphire crystal with anti-reflective coating and the Super-LumiNova® dial treatment ensure the watch functions at depth as precisely as it reads in a brightly lit room. All UNIMATIC divers are individually pressure-tested to 300m minimum, with a screw-down crown and caseback and a mono-directional safety bezel rated for professional use.
