Description
Modello Uno ref. U1-GMT-DHBR is a Made in Italy GMT diver watch. It features a tropic brown dial with markers in Super-LumiNova® GL light old radium and matte black 24h bezel insert.
Time is displayed thanks to the matte black ladder phantom hands set and the reverse lollipop second hand with matte white tip. The double domed anti-reflective sapphire crystal provides the best performance in every light condition.
The solid 316 brushed stainless steel case, the screwed-in 2mm thick caseback, the 8mm diameter crown together with the high quality gaskets set provide a water resistance tested individually to 30 atm=300m=1000ft.
Timing accuracy is guaranteed by the NH34A automatic movement tuned to 21600bph with 41h power reserve and hacking second hand. It comes on a tropic brown tapered 22-20mm quick-release two-piece TPU strap with stainless steel brushed hardware signed UNIMATIC.
The Diving Heritage screw-down caseback features the individual progressive number. The watch is covered by a 24-month worldwide warranty and is part of a unique edition of 300 pieces.
Diving Heritage, a modern tribute to the enduring legacy of classic dive watches and the evocative atmosphere of the Italian Riviera.

VINTAGE SPIRIT, MODERN BUILD
UNIMATIC’s classic diver design is a modern reinterpretation of timeless tool-watch aesthetics — stripped down to essentials with bold legibility, clean geometry, and a utilitarian edge. Characterized by its oversized crown, stark dial with luminous markers, and unidirectional bezel, it channels vintage military influences while embracing contemporary minimalism.
CUSTOM Variable font
The UNIMATIC number typefaces reference this traditional lettering found on such classics of military watch making. Yet they combine this with more recent examples of watch typography, as found in the most famous recent watches. These rather modern and geometric number styles reference a Bauhaus and German »DIN-Norm« aesthetic: Perfectly round inner forms with almost no line contrast. By using the most basic geometric forms such as circles and straight angles these kinds of typefaces feel very familiar and established therefore emanating clarity and reliability.
HERITAGE: THREE WAYS
Whether tracking time zones or timing a dive, the Heritage Diver, Heritage GMT Diver, and Heritage Chronograph Diver offer purpose-driven versatility. Equipped with Japanese Seiko calibers and limited to 300 numbered units per reference, each watch is finished with a color-matched quick-release TPU strap for a unified, wear-anywhere look. Classic design meets modern engineering—ready for the next chapter of exploration.
