UNIMATIC Launches First GMT Collection Powered by Seiko NH34A Movement: A Closer Look at Modello Uno and Modello Quattro

UNIMATIC has launched its first GMT collection powered by the Japanese Seiko NH34A movement, designed specifically for modern travelers and watch enthusiasts. This collection features two models, the Modello Uno ref. U1-GMT and the Modello Quattro ref. U4-GMT, both of which blend practical functionality with refined design. These timepieces cater to those who need precise timekeeping across multiple time zones.

Modello Uno U1-GMT: A Limited Edition Diver’s Watch

UNIMATIC released the Modello Uno ref. U1-GMT as a limited edition diver’s watch, with only 300 pieces available globally. The watch comes with a 40mm case diameter and a 41.5mm bezel, made from 316 stainless steel with a brushed finish. Its matte black dial, paired with Super-LumiNova® C1 white markers and a matching 24-hour bezel insert, ensures clear readability in all lighting conditions. Additionally, the watch features a 2.5mm thick double-domed sapphire crystal with an anti-reflective coating on the inner side, which enhances visibility.

The automatic caliber Seiko NH34A powers this model, operating at a frequency of 21600bph and offering a 41-hour power reserve. This setup ensures reliable timekeeping. The hacking seconds hand allows for precise time setting, while the GMT function lets the wearer track time in two different zones simultaneously. Moreover, the Modello Uno U1-GMT offers water resistance up to 300 meters, making it suitable for diving and other aquatic activities.

The watch includes a charcoal gray tapered 22-20mm quick-release two-piece TPU strap, with stainless steel brushed hardware signed by Unimatic. UNIMATIC individually numbers each piece and provides a 24-month worldwide warranty.

Modello Quattro U4-GMT: A Military-Inspired GMT Watch

The Modello Quattro ref. U4-GMT, another limited edition with only 300 pieces available, features a robust design inspired by military aesthetics. The 40mm stainless steel case includes a fixed monoblock bezel with 24-hour markers deeply acid-etched onto its surface, providing a distinct and durable look.

This model also uses the Seiko NH34A automatic movement, offering the same 21600bph frequency and 41-hour power reserve as the Modello Uno. Its matte black dial, combined with Super-LumiNova® C1 white markers and cool gray open second rail and dial trims, ensures clear readability. The 2.8mm thick flat sapphire crystal, treated with an anti-reflective coating, protects the dial while maintaining clarity.

Similar to its counterpart, the Modello Quattro U4-GMT offers water resistance up to 300 meters. It comes with a charcoal gray tapered 22-20mm quick-release two-piece TPU strap. The caseback features an Unimatic Timezone engraving and the individual progressive number. UNIMATIC provides a 24-month worldwide warranty with each watch.

Conclusion

UNIMATIC’s new GMT collection, which includes the Modello Uno ref. U1-GMT and Modello Quattro ref. U4-GMT, marks a significant milestone as the brand’s first GMT watches powered by the Seiko NH34A movement. These timepieces offer a compelling blend of precision, durability, and refined design, catering to both collectors and enthusiasts. With limited availability, these models are likely to become sought-after items within the watch community. For more information, visit the official UNIMATIC website.
