One shouldn’t play golf with a mechanical watch unless that watch is a Jaermann & Stübi. Our watches have the special shock absorber developed for the game of golf, which protects the inner mechanisms of the watch against strokes and impact. This patent pending innovation was developed and tested with golf professionals. The ShockGuard is visible through the back made of scratchproof sapphire glass. The back is hermetically attached to the case by six screws. The watch case itself is waterproof up to a depth of 100 meters.
