The Tempest is the ultimate stripped back navigator watch designed for pure adventure. Powered by a self-winding NH35A, 21,600 BPH automatic, 24 jewel movement, the Automatic variant is built in Germany, finished in the UK, and comes with a waterproof NATO strap made in Italy from sustainably-sourced rubber.
