T50 1052.020

Developing and using “unconventional” case materials for watchmaking is one of our core competencies. It is deeply rooted in our company’s historical DNA and has produced a number of astonishing timepieces in the past. The T50 GBDR edition is another impressive demonstration of our extensive expertise in the field of metallurgy.For the diver’s bezel of this interesting timepiece, we are using a bronze alloy we developed, which is patented. This alloy, referred to as Goldbronze 125, has an exceptionally high degree of purity, and one eighth of it is gold. With bronze, we are embracing a material that has been used frequently in a wide range of maritime applications in the past. However, the exceptionally high degree of purity of our Goldbronze 125 results in improved skin compatibility and increased corrosion resistance to seawater compared to conventional bronze alloys. Material-technically matching this, the case of the T50 GBDR is made of high-strength titanium. As this metal does no...
