The Goldbronze 125, developed and patented by us and used for the case, the crown and the bezel of this timepiece limited to 300 pieces, impresses with its exceptional purity and radiates modern elegance and timeless aesthetics when combined with the dark blue dial. With these attributes, this watch exudes style in leisure, business, and special occasions alike.
Clear readability and precision
This concept does not compromise on precise time measurement, thanks to its minimalist display. Prominent, large sword hands and the restrained design of all elements irrelevant to diving—such as additional functions or markings on the dial and captive bezel—form essential design features. For secure readability, especially of reference times in darkness or under adverse visibility conditions, the watch employs colour coding: the hour hand and dial indices glow green, while the minute and second hands, as well as the main marker on the bezel, glow blue. Additionally, the crown is located at 4 o’clock and prevents pressure on the back of the hand, even during physically demanding activities.
Technical elegance with high functionality
The T50 GOLDBRONZE B embodies a design that emphasizes technical sophistication and prioritizes operational safety above all else. The Goldbronze 125 harmonizes seamlessly with the perfectly legible dark blue dial, giving the watch an elegant appearance. The deep blue also evokes the depths of the ocean while its silky matte finish provides a refined contrast to the Goldbronze 125 used for the case, crown and bezel.
The robust safety diver’s bezel proves to be an exceptionally reliable tool for measuring time. Securely attached to the case, it is both non-detachable and safeguarded against accidental adjustments. This is the memorable principle behind the simple yet effective anti-twist mechanism: “Press first, then turn.” This ensures the bezel stays in place under demanding conditions.
As an additional safety feature, the Ar‑Dehumidifying Technology enhances functionality and prevents fogging, ensuring reliability even in challenging environments.
Expertise in metallurgy
With the T50 GOLDBRONZE B, we once again showcase our exceptional expertise in the field of metallurgy. To fully appreciate the value of this remarkable timepiece, it is important to note that we use a proprietary bronze alloy developed in-house. This Goldbronze 125 is composed of one-eighth gold and features an exceptionally high degree of purity in its alloy components.
Bronze, historically favored for a wide range of maritime applications, takes on a new dimension in Goldbronze 125. Its extraordinary purity enhances both skin compatibility and corrosion resistance to seawater. While Goldbronze 125 also naturally develops a darker patina through oxidation, the inclusion of gold in the alloy significantly reduces its reactivity to environmental influences. As a result, the surface darkens much more slowly than conventional bronze. Additionally, light oxidation can be easily removed using the special Goldbronze cleaning cloth provided with the watch.
To eliminate the possibility of skin reactions entirely, the T50 GOLDBRONZE B is equipped with a titanium case back, combining technical ingenuity with wearer comfort.
Propeller of Submarine U 15 made from ship’s bronze and the T50 GOLDBRONZE crafted from Goldbronze 125
The use of exceptional materials creates a fascinating connection between our company and the ship’s bronze propeller (commonly referred to as a ship’s screw) of the submarine U 15, a submarine of the German Navy’s Class 206. Ship’s bronze has a long-standing tradition, particularly in the manufacture of ship’s propellers designed for seawater applications.
For us, the skin compatibility of case materials in watchmaking is equally important. The reality is that this characteristic has been significantly limited in all conventional bronze alloys to date. Therefore, we have taken the innovative step of further developing bronze as a case material. The result is our patented Goldbronze 125 alloy, which was first introduced in 2023 with our diver’s watch, the T50 GOLDBRONZE.
Goldbronze 125 represents a breakthrough by combining the maritime heritage of bronze with improved skin compatibility and enhanced resistance to seawater, making it a revolutionary choice in the world of watchmaking.
