Military watch Mühle-Glashütte S.A.R. Flieger-Chronograph
Starting from 3.800 €The Mühle-Glashütte S.A.R. Flieger-Chronograph is a military aviation watch developed in 2010 with German Navy rescue pilots. Designed as a mechanical backup instrument, it combines a substantial 45 mm stainless steel case, immediate legibility and controls adapted to operational conditions. Its start pusher, positioned at 8 o’clock, can be operated easily while wearing gloves and avoids pressing against the back of the hand during flight. The clearly marked 10-second scale supports timing measurements used for airspeed calculations. Powered by the automatic MU 9413 calibre with a 62-hour power reserve, the watch is available with either a black rubber strap or a stainless steel bracelet.
Mühle-Glashütte S.A.R. Flieger-Chronograph military aviation watch
Mühle-Glashütte develops timekeeping instruments based on precision, durability and rapid readability. The S.A.R. Flieger-Chronograph reflects this professional philosophy particularly well. Its story began in 2010, when German Navy rescue pilots required a chronograph capable of withstanding the demands of airborne missions while supporting specific flight-related calculations. The brand therefore created a mechanical watch adapted to Sea King crews, with an unconventional architecture shaped by operational needs rather than purely aesthetic considerations.
The watch notably features a large start pusher positioned at 8 o’clock. This layout makes it easier to operate while wearing gloves and prevents the pusher from pressing against the back of the hand when the pilot is handling the aircraft controls. Its clearly graduated 10-second scale also serves a practical purpose, allowing timing measurements used to calculate airspeed.
The S.A.R. Flieger-Chronograph therefore differs from a conventional pilot’s watch merely inspired by historical instruments. It was developed from a genuine military specification connected to search-and-rescue operations. Its 45 mm case, strongly contrasted black dial and orange chronograph indications prioritise immediate readability. This functional identity is completed by an automatic movement incorporating features associated with Glashütte watchmaking, including a three-quarter plate and Mühle’s Woodpecker neck regulation system.

The Mühle-Glashütte S.A.R. Pilot Chronograph Military Watch
The Mühle-Glashütte S.A.R. Pilot Chronograph has the unmistakable identity of a true tool watch. Its development alongside German Navy search and rescue pilots explains many of its ergonomic design choices. The case measures 45 mm in diameter, 16.2 mm thick and 54 mm lug-to-lug, and is made from stainless steel. These generous dimensions give the watch a strong wrist presence while, above all, making the displays larger and allowing the time and chronograph readings to be taken quickly in an operational environment.

The black dial clearly separates the timekeeping and chronograph functions. The hands and indices are coated with Super-LumiNova, while the chronograph indications are highlighted in orange. This visual distinction enables the pilot to identify the current time and elapsed time immediately. Legibility is therefore a key element of the watch, rather than simply an aesthetic choice.
The watch also features a bidirectional rotating bezel, an anti-reflective sapphire crystal, a screw-down crown and a transparent caseback allowing the movement to be observed. Its chronograph is complemented by a date display. The most distinctive feature, however, is the oversized start pusher positioned at 8 o’clock. This unusual layout allows it to be operated comfortably with gloves without restricting hand movement during flight. The S.A.R. Pilot Chronograph is therefore a genuine military aviation watch, developed around the needs of crews involved in search and rescue missions.
A Chronograph Designed for Search and Rescue Pilots
The MU 9413 calibre powers the hours, minutes, seconds, date and chronograph functions. This automatic movement features a Glashütte three-quarter plate, a construction traditionally associated with Saxon watchmaking. It also incorporates the Woodpecker regulation system, developed by Mühle-Glashütte to improve adjustment stability. The hacking seconds function stops the seconds hand while setting the time, and the date can be adjusted quickly. Its power reserve reaches 62 hours, allowing the watch to remain unworn for more than two days. The 10-second scale is directly linked to the watch's aviation origins. Requested by search and rescue pilots, it facilitates the measurements used to calculate airspeed. The large dial diameter also makes the chronograph easier to read quickly, especially when the wearer is using gloves or working in a moving environment.

With a water resistance of 10 bar, equivalent to approximately 100 metres, the watch is suitable for everyday use and regular contact with water. This specification matches its naval heritage, but does not make the S.A.R. Pilot Chronograph a professional dive watch. Its natural environment remains military aviation and maritime rescue.
Two configurations are available. Reference M1-41-33-KB is fitted with a black rubber strap with a folding clasp, while reference M1-41-33-MB comes with a metal bracelet. Both versions retain a 22 mm lug width. They are not supplied together: each bracelet corresponds to a separate reference and price.
Mühle-Glashütte S.A.R. Flieger-Chronograph pilot’s watch: a rescue instrument
The Mühle-Glashütte S.A.R. Flieger-Chronograph is a military aviation watch developed with German Navy rescue pilots. Its 45 mm stainless steel case houses a highly legible black dial, while the orange chronograph indications help distinguish measured times at a glance. The start pusher positioned at 8 o’clock can be operated while wearing gloves without interfering with hand movement during flight. The automatic MU 9413 calibre provides up to 62 hours of power reserve. Available with either a rubber strap or a stainless steel bracelet, this tool watch combines operational design, chronograph functionality, a 10-second scale and characteristic Glashütte watchmaking details.
Movement
The watch is powered by the automatic MU 9413 calibre. It features a Glashütte three-quarter plate, the Woodpecker regulation system, a hacking seconds function and a quick-set date. Its power reserve reaches 62 hours, providing comfortable autonomy for a mechanical watch worn regularly.

Diameter and Materials
The stainless steel case measures 45 mm in diameter, 16.2 mm thick and 54 mm lug-to-lug. Its generous proportions enhance the legibility of the displays. It features a bidirectional bezel, an anti-reflective sapphire crystal, a screw-down crown and a transparent caseback revealing the movement.

Water Resistance
The S.A.R. Pilot Chronograph offers 10 bar of water resistance, equivalent to approximately 100 metres. This level of water resistance is suitable for everyday activities, swimming and maritime environments. However, it remains below the level expected of a true professional dive watch equipped with a unidirectional timing bezel.

Accessories
Two versions are available separately. Reference M1-41-33-KB, priced at €3,800, is fitted with a 22 mm black rubber strap and a folding clasp. Reference M1-41-33-MB, priced at €4,050, comes with a metal bracelet of the same width, also equipped with a folding clasp.

Warranty
Mühle-Glashütte provides a 24-month manufacturer's warranty from the date of purchase. It covers manufacturing defects affecting the operation of the watch. Repair and servicing work carried out in the brand's workshop is also covered by a separate two-year warranty.
