'Altitude' Pilot's Watch (36mm) | Blue Stack
Inspired by classic tool watches designed for jet aviation, the Altitude is built for the open air and the highest peaks. A fully automatic timepiece—like the Atlantic—the Altitude is built in Zurich, finished in the UK and comes with a single-piece waterproof strap made in Italy from sustainably-sourced rubber.
The brushed stainless steel case with integrated lugs, curves to fit snug against your wrist. This 'tonneau' design gives the Altitude a much more substantial feel than the dimensions suggest.
Our design principles: purpose, performance and planet, have informed every detail of the Altitude. The grained, anti-glare dial is protected by domed, hardened mineral crystal, with hands and markers set in LumiNova – ensuring legibility whatever the weather.
Water-resistant to 10 ATM (100 metres, 330 feet), you can take the Altitude with you on even the most testing hiking, climbing, or ocean expedition. But with its understated utilitarian look, the Altitude is also the perfect watch to wear everyday.
The Blue Stack edition is distinguished by its blue rubber strap.
The Altitude is powered by a self-winding NH35a, 21,600 bhp 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.
