The "Seve Ballesteros II" model by Jaermann & Stübi is equipped with an automatic movement as well as course timer and GMT functions. A patented shock absorber with a flexible stem cushions the impacts during a golf game and protects the movement. Each watch is individually numbered and the iron used for the watch case is engraved on the back. A certificate signed by Seve Ballesteros also attests to the authenticity of the irons used.
