THERMOSPHERE, 42 mm, Steel bracelet

Limited to 112 pieces Hanhart THERMOSPHERE A new limited special edition now joins the collection of the Black Forest watchmaker Hanhart: the THERMOSPHERE. Limited to 112 pieces, its production number references the European emergency number for fire and rescue services. Reduced to the essentials and clearly built for operational use, the THERMOSPHERE places function and resilience at the centre. It was developed for situations in which technical reliability is not optional, but essential. DESIGNED FOR THE EXTREME BUILT FOR THE MISSION. AGAINST THE CLOCK. With the THERMOSPHERE Limited Edition, Hanhart introduces a special model limited to 112 pieces, inspired by respiratory protection monitoring in firefighting. Developed in collaboration with the Baden-Württemberg State Firefighters Association, the watch transfers key time markers from a breathing apparatus operation onto the rotating bezel. In doing so, the model combines a robust operational aesthetic with a clear functional concept. 112 PIECES The inspiration: timing a breathing apparatus operation When dense smoke swallows every sense of direction and reduces visibility to just a few centimetres, only one reliable constant remains: time. For firefighters operating with breathing apparatus, time is far more than a measurement. It defines safety, performance and the room for action available to the crew. Under zero-visibility conditions and extreme physical strain, the surrounding environment loses all definition. Decisions are no longer based on what can be seen, but on what remains available: breathing air. Every operation follows a precise time window, defined by the limited service duration of the breathing apparatus and the requirements of respiratory protection monitoring. This is precisely the reality from which THERMOSPHERE was born. Shaped by the experience of firefighters in Baden-Württemberg and developed with a focus on those who take responsibility under the most demanding conditions. THERMOSPHERE makes time visible — creating orientation where it is needed most. SPECIAL ELEMENT – 112 IDENTITY IN EVERY DETAIL At the center of the design is the rotating bezel with its distinctive triangular luminous markers. These are based on the time checkpoints used in breathing apparatus monitoring and provide intuitive readability. At the start of a breathing apparatus operation, the solid triangle on the bezel is aligned with the position of the minute hand. The maximum operational duration, limited by the available breathing air supply, can then be read directly: typically 30 minutes when using a single air cylinder and 60 minutes when using two cylinders. The different symbols on the markers indicate both the total duration and the intermediate time checkpoints. A distinctive design feature is the 112 at the 12 oclock position. As the Europe-wide emergency number, it symbolises readiness, responsibility and service to others. The colour accent on the first digit deliberately highlights its dual meaning, turning this defining element into a bold and characterful focal point. DEVELOPED FOR THE MISSION Scratch-resistant sapphire crystal and 30 ATM water resistance The THERMOSPHERE was developed for people who need to rely on their equipment at all times. Equipped with a Hookstrap™ textile strap, it combines exceptional wearing comfort with maximum flexibility. The elastic material is quick to put on, individually adjustable and can easily be worn over operational and protective clothing. For different requirements and style preferences, the THERMOSPHERE is also optionally available with a high-quality stainless steel or rubber strap. Scratch-resistant sapphire crystal reliably protects the dial against the stresses of everyday use. With water resistance of 30 bar, equivalent to approximately 300 metres, the THERMOSPHERE remains a dependable companion even under demanding conditions — on duty, in training and in everyday life. DARKNESS? NO PROBLEM SUPER LUMINOVA® The hands and numerals of the Hanhart Thermosephere are coated with Super-LumiNova® to ensure optimum readability by day and night.
