Hanhart’s Thermosphere turns a diver into a firefighter’s timer

Hanhart developed the Thermosphere with the Baden-Württemberg State Firefighters’ Association, adapting its professional dive-watch platform to respiratory-protection timing. The blue ceramic bezel carries triangular checkpoints for monitoring a breathing-apparatus operation, while the highlighted 112 on the dial references Europe’s emergency number.

The 42mm steel case measures 12.95mm thick and is water-resistant to 30 bar. A convex sapphire crystal covers the dark blue dial, whose hands and markers use Super-LumiNova. The automatic movement is specified as either a Sellita SW200-1 or Soprod P024, with a 38-hour reserve.

Hanhart limits the Thermosphere to 112 numbered pieces. Buyers can choose an elastic Hookstrap designed to fit over protective clothing, rubber or steel. The special bezel gives the watch a real procedural function rather than relying only on firefighting colours and insignia.
