From the Manufacturer:
The second new addition to the BR03-92 Diver collection evokes the historical roots of underwater exploration. Its case and bezel are made from bronze, a material used in the past for diving helmets. Although inalterable, bronze can also form a patina with time depending on its environment, gaining a unique shade over the years.
This allusion to the origins of underwater adventures can be seen on the case-back thanks to an engraving of a diver. The aged leather strap con rms the watch’s authentic vintage spirit, but can be replaced with a rubber strap for use while diving.
Boasting exceptional technical and aesthetic qualities, this model is issued as a limited edition of 999 pieces.
