One shouldn't play golf with a mechanical watch unless that watch is a Jaermann & Stübi. Our watches have a special shock absorber , the Shock-Guard, 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 the help of golf professionals. The watch case itself is made of high-quality steel, titanium or 18-carat gold and is waterproof up to 100 meters.
