T-Five
Beigua Maris
Our mission is to revive the spirit of the golden age of watchmaking, when design, function, and emotion merged into timeless instruments of adventure. The new T-Five Beigua Maris embodies that philosophy, blending the soulful aesthetics of mid-century divers with the precision and resilience of modern Swiss engineering.
Crafted in Grade 5 titanium, the Beigua Maris is light yet extraordinarily strong, a contemporary expression of endurance and refinement. Its form recalls the skin divers of the 1960s: compact, readable, and purposeful, yet every surface and proportion has been re-imagined for today’s standards of performance and comfort.
- Launch date is November 13, 4.00p.m. CET
- Deliveries will start from January 10
- Launch price of T-Five Beigua Maris is Euro 1,200
From nature to the watch
The inspiration
The name Beigua Maris draws inspiration from the seashores of Mount Beigua, one of Italy’s most spiritual and untamed landscapes. There, the mountain meets the sea in a collision of wind, rock, and water, a place where nature seems alive, and where one of Europe’s richest titanium reserves lies beneath the surface. A connection between earth and sea, between heritage and innovation, defines the T-Five Beigua Maris. It is not just a diver’s watch, but a symbol of the elements that forged it: raw, enduring, and deeply powerful.

The Philosophy behind the project
The T-Five Beigua Maris is built as a true professional instrument, with its 39mm case engineered for durability, precision, and refined aesthetics.
The Grade 5 titanium ensures exceptional strength with an ultra-light feel on the wrist, offering both solidity and comfort in extreme conditions. The titanium bezel is complemented by a matte ceramic insert, combining vintage-inspired charm with scratch-resistant modern performance.
Water resistance reaches an impressive 30 ATM (300 meters), ensuring reliability both above and beneath the waves.

Core and soul
At its heart lies the La Jeux Perret G101, the Swiss automatic movement with a 68-hour power reserve, renowned for its precision and refined finishing. This movement grants precision and an impressive power reserve.
The dial is bi-zonal, with a distinctive inner minute track that enhances legibility and adds depth to its design. Every detail, from the applied indices to the precise alignment of the bezel and curvature of the ultra-bombé sapphire crystal evokes the classic divers of the 1960s while delivering modern clarity and protection.
Each component is executed to the highest standards, reflecting Trematic’s dedication to both mechanical excellence and timeless design.
The finishing and colors available
T-Five Beigua Maris features a fine-grained sandblasted finish, accented by polished and brushed details on the carrure, bezel, caseback, and crown.
Available in three colorways — Shadow, with its grey-to-charcoal degradé dial and Lumicast indexes glowing in Super-LumiNova BGW9; Desert and Marina, both featuring full-lume bi-zonal dials combining BGW9 and Old Radium tones.
It comes fitted with a technical FKM strap reinforced by a hydro-repellent textile insert and a deployant clasp for maximum comfort and endurance, plus an additional vintage-style strap matching the dial.
From sea to shore, the Beigua Maris embodies the contemporary diver — forged in titanium, powered by Swiss mastery
