1970 Watch Grey

Many water resistant watches were developed before, but the principle of a compressing case back allowed to reach new depths. Add to that an inner bezel that would time a dive, and those instruments soon became irreplaceable on the wrists underwater.

Obviously, everything was made to provide the highest legibility, with large handset and indexes, and bright colors. The orange tint proved very popular, especially against a black background. Those watches were also substantially bigger as they were worn above the diving suit, and their large second crown controls the fundamental inner bezel, set to indicate the maximum dive.
