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.

Additional Product Details
Sinn Watches was formed in 1961 by the legendary pilot and flight instructor Helmut Sinn. They began manufacturing flight watches based on his extensive aviation experience, this was primarily based on Mr. Sinn's dissatisfaction with the watches that were available for pilot and navigational purposes at that time. His own designs incorporated the features and functionality that he felt more fit for purpose as an instrument watch. This is a design philosophy that has transcended the company's culture right through to the present day. Sinn is now the world's most eminent manufacturer of high quality, precision, functional and purposeful instrument watches. From the beginning, their emphasis was on creating special purpose instruments that performed under extremely adverse operating conditions such as high speed, high and low pressures and altitudes, intense heat or pressure, extreme cold, high magnetic interference, and submergence in liquids. Sinn are becoming increasingly known for their instrument watches, and are today a force to be reckoned with as they lead the way in instrument watch design. The company changed hands in 1994 when Lothar Schmidt formerly of IWC assumed control and further expanded the boundaries of Sinn’s high tolerance manufacturing expertise. Over the past decade, Sinn has pioneered some innovative new technologies, including oil filled watch chambers to enable operation under extreme pressures, argon gas filled watches to prevent moisture infiltration, impact resistant gear suspensions, and new micro-lubricating techniques. Their timepieces are standard equipment in some of the most dangerous and adverse environments on earth - little surprise their watches are issued to the German military and elite forces. Above all the watches are manufactured and marketed to the world at large. Like the designs and their application areas, the pricing of the Sinn watches is most aggressive, making them available to most people. Due to distribution agreements Sinn watches can only be shipped to the UK and Ireland and certain countries where there is no Sinn agent assigned to that territory. Sinn watches are covered by a two or three year manufacturers warranty depending on the model.
