Inspired by the Northern hemisphere’s cold saltwater – meet the Arctic, a mechanical diver's watch engineered in Germany and accompanied by a waterproof strap made in Italy from sustainably sourced rubber.

Rotate North's design principles; purpose, performance and planet, have informed every detail of the Arctic. The black dial is protected by sapphire crystal, encased in a matt ceramic bezel, with the hands and markers set in LumiNova, ensuring legibility whatever the conditions. 

Water-resistant to 50 ATM (500 metres), and with a helium escape valve, the Arctic is a serious diver's watch, able for the toughest of challenges. However, it's also an easy watch to wear every day, comfortable and understated.

The Seal Black NATO edition is distinguished by its plain black NATO strap.


The Arctic is powered by a self-winding NH35A, 21,600 BPH automatic, 24 jewel movement, with 41 hour power reserve when fully wound. This robust, mechanical movement is powered entirely by renewable energy drawn from the wearer's own arm movements - no batteries are required. It is exceptionally accurate, highly serviceable and ready for generations of active use.
