Description
Modello Tre ref. U3-DHB is a Made in Italy chrono-diver. It features a mono-eyed matte black dial with markers in Super-LumiNova® GL light old radium, matching the dot on the matte black heritage diver aluminium insert, white matte open second rail and dial trims.
Time is indicated thanks to the matte black ladder phantom H+M, reverse lollipop S, matte white tip. The 2.5 mm thick double domed anti-reflective sapphire crystal provides the best performance in every light condition.
The solid 316 stainless steel case with a brushed finish, the screwed-in 2 mm thick caseback, the 8 mm diameter crown coupled with fat 5.5 mm screw-in pushers, together with the high quality gaskets set provide a water resistance tested individually to 30atm=300m=1000ft.
Timing accuracy is guaranteed by the VK64 meca-quartz movement tuned to 32,768 Hz for 3 years battery life, with 1/5 of a second indication plus 60 minutes counter. Comes on a matte black tapered 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.

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.
