For the diver’s bezel of this interesting timepiece, we are using a bronze alloy we developed, which has a patent pending. 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 not cause allergies, the watch provides exceptionally high wearing comfort overall. Although the surface of Goldbronze 125 darkens due to oxidation, developing a patina, we achieve inertia against environmental influences with the gold alloy component. The surface darkens much more slowly than with ordinary bronze. The darkening can also be easily removed using the special gold bronze care cloth we provide.
