The showpiece of the watch is the stamped steel case back. It is a first in the watchmaking industry to apply this intricate engraving to the hard stainless steel with such great detail. The very deep engraving creates a kind of 3D character of the image. We gave our case maker a very difficult task and accepted the extremely high cost to produce this intricate engraving. The cost of the engraved back is 5 times the cost of a normal steel back. Although this type of engraving has never been tried before, we took on this project not to come out with just any diving watch, but to create something new and original. However, as with all our watches, we keep the design very simple and timeless.
