'Atlantic' Dive Watch (40mm) | Marine Steel Cat.2

£351.00 £390.00

A durable, versatile tool watch inspired by the Northern hemisphere’s cold saltwater – meet the Atlantic, our debut timepiece… a mechanical diver's watch engineered in Germany paired with a stainless steel bracelet.

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

Water-resistant to 30 ATM (300 metres), you can take the Atlantic with you on even the most testing diving, surfing, or wild swimming expedition. However, it's also an easy watch to wear every day, comfortable and understated.

The Marine Steel Cat.2 variant is paired with a mesh-style stainless steel bracelet, with easy release adjustable clasp, to ensure a comfortable fit at all times.


The Atlantic 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.
