French Air Force watch: history, brands and military-issued models
The French Air Force watch holds a distinctive place in the history of French military watchmaking. From the Type 20 chronographs of the 1950s to contemporary pilot watches, it reflects the evolution of the instruments used by pilots and aircrews. Several manufacturers, including Breguet, Dodane, Auricoste and Vixa, have contributed to this history. However, not all watches associated with military aviation are officially issued models. This article explores the origins, characteristics and leading brands associated with French Air Force watches.
The history of French Air Force watches
The history of military aviation watches is closely linked to the development of aviation during the 20th century. From the earliest decades, pilots needed instruments to measure time, navigate and coordinate various operations. Wristwatches offered several advantages over pocket watches: they remained accessible during flight and allowed pilots to check the time quickly. As aircraft and missions evolved, requirements for legibility, durability and timekeeping became increasingly important. In France, the Air Force became an independent branch of the armed forces in 1934. Following the Second World War, the modernisation of its equipment accompanied the introduction of new aircraft and advances in navigation techniques. Against this background, the French military authorities established specifications in the early 1950s for the procurement of chronographs for the Air Force. This initiative led to the creation of the Type 20, one of the best-known historical references in French military watchmaking.
The Type 20: the iconic French Air Force watch
The Type 20 was not originally a brand or a single commercial watch model. It referred to a set of technical specifications established to meet the requirements of French military aviation. Several manufacturers produced chronographs that complied with these requirements. The first deliveries took place in the mid-1950s. These watches were intended to enable aircrews to measure successive time intervals, with relatively simple operation and good legibility.
Military specifications
Historical Type 20 chronographs were associated with several technical characteristics:
- A hand-wound mechanical movement.
- A chronograph function with retour en vol, also known as flyback.
- A black dial with luminescent markings.
- A rotating bezel for tracking elapsed time.
- A minimum power reserve of 35 hours.
- Requirements for accuracy, reliability and resistance to repeated operation.
Historical specifications notably mention a daily accuracy tolerance of approximately eight seconds and the ability of the chronograph mechanism to withstand several hundred operations. These characteristics must be considered within the technological context of the 1950s. Electronic instruments and modern navigation systems did not yet offer the same capabilities or level of integration.
Why was the flyback function important?
The flyback function, or retour en vol, allows a running chronograph to be reset to zero and immediately start a new measurement. On a conventional chronograph, this operation generally requires three successive actions: stopping, resetting and restarting. The flyback function simplifies this procedure by allowing consecutive time measurements. This feature was particularly useful for certain aerial navigation operations and the timing of flight sequences. Today, it remains one of the watchmaking complications most closely associated with French military chronographs.
The main French Air Force watch brands
Several watchmakers supplied chronographs to the French Air Force. Their historical role should be distinguished from that of brands currently marketing watches that are simply inspired by aviation.
Breguet: a historical reference in Type 20 watches
Breguet is among the best-documented manufacturers in the history of French Air Force-issued watches. In the early 1950s, the company developed a chronograph that met the requirements of the French military authorities. Series production began in 1954. The watches were mainly delivered to the French Air Force between 1955 and 1959. Other examples were supplied to the Flight Test Centre (Centre d'Essais en Vol) and French Naval Aviation. These chronographs were issued as military equipment and, in principle, remained the property of the French state. Breguet also developed civilian versions, helping to introduce the Type XX family to a wider audience. Today, the brand maintains this historical connection through its Type XX and Type 20 collection.
Dodane: a specialist in aviation chronographs
Dodane holds an important place in the history of French military chronographs. The watchmaker is particularly associated with the Type 20 and Type 21, the latter representing an evolution of the chronographs used by the French armed forces. Historically, Dodane watches have been characterised by their functional design and their suitability for aviation timekeeping requirements. The Dodane name is also linked to other watch brands associated with the history of these chronographs, notably Airain and Chronofixe.
Auricoste: between aviation and military watchmaking
Auricoste is also among the historical manufacturers of Type 20 chronographs. The brand has a broader history in French military watchmaking, with established connections to the French Navy. Its aviation chronographs from the 1950s feature the main characteristics expected of Type 20 watches: a legible dial, a mechanical movement and a flyback function. Vintage examples are now studied by collectors, particularly for their dial variations, movements and military markings.
Vixa: a distinctive military chronograph
Vixa is another name associated with Type 20 watches supplied to the French armed forces. Its chronographs from the 1950s are particularly notable for their use of movements linked to the German manufacturer Hanhart. This distinctive feature reflects the industrial exchanges and restructuring of European watchmaking following the Second World War. Today, Vixa Type 20 watches represent a distinct category among collectible French military chronographs.
Airain and Chronofixe: other names worth knowing
Airain and Chronofixe also feature in the history of French aviation chronographs. These names are particularly associated with watches produced in connection with Dodane. Airain's history also extends to the French Army Light Aviation (Aviation légère de l'Armée de terre, or ALAT). It is therefore important not to automatically attribute all historical watches bearing this brand name to the French Air Force. The different military assignments should be examined through available references, contracts and historical documentation.
What is an officially issued French Air Force watch?
A military-issued watch is a timepiece supplied as part of the equipment provided to military personnel or units. In the case of Type 20 chronographs, watches delivered to the French Air Force generally remained the property of the French state, which was responsible for their maintenance and servicing. This differs from a watch purchased privately by a service member, even if worn while on duty. It also differs from a civilian watch featuring a military insignia or referencing a particular squadron.
Military watch markings
Some French military-issued chronographs feature specific engravings on their case backs. These may include contract numbers, individual serial numbers and information relating to technical maintenance. The FG marking, generally understood to mean “Fin de Garantie” (End of Warranty), is particularly familiar to Type 20 collectors. It relates to a system for tracking maintenance deadlines. However, military markings alone do not constitute definitive proof of authenticity. They should be assessed alongside the watch reference, movement, production period and, whenever possible, archival documentation.
Type 20 and Type 21: what are the differences?
The Type 21 emerged as a continuation of the Type 20 chronographs, incorporating changes to the technical specifications and configurations. Both families shared a common purpose: providing a timekeeping instrument suited to the needs of aircrews. However, their exact characteristics may vary depending on the manufacturer, production period and military contract. It would therefore be an oversimplification to regard the Type 21 as a single watch model or merely an updated version with identical specifications across all manufacturers. Correctly identifying a vintage example requires a detailed examination of its specific configuration.
French Air Force watches today
Since 2020, the institution has officially been known as the French Air and Space Force (Armée de l'air et de l'espace). Navigation and timekeeping equipment have evolved considerably since the 1950s. Modern military aircraft are equipped with integrated electronic systems that perform many functions once associated with individual instruments. Nevertheless, wristwatches can still serve a practical purpose for checking the time and monitoring certain activities. There is no reason to assume that all French Air and Space Force pilots currently wear the same officially issued mechanical watch. Practices may vary depending on units, roles, available equipment and individual preferences.
Unit watches, special editions and civilian models
The contemporary market includes several categories of watches associated with military aviation:
- Watches developed for a particular military unit or training class.
- Commemorative editions referencing an aircraft or squadron.
- Civilian models inspired by historical chronographs.
- Privately owned watches worn by military personnel during their duties.
These categories should not be confused with historical military-issued watches. The presence of an insignia, roundel or reference to the French Air Force on a dial does not necessarily demonstrate the existence of an official military supply contract.
How can you identify an authentic French Air Force watch?
Identifying a vintage military watch generally requires several checks. The first involves verifying that the model is consistent with known periods of military issue. The movement type, case dimensions, dial configuration and functions should correspond to the expected historical specifications. The second concerns military markings and any accompanying documentation. Finally, it is important to consider modifications made during the watch's lifetime, such as dial replacements, changes of hands, movement servicing or case alterations. These interventions may be consistent with historical military use, but they affect the watch's originality and historical significance. For the most sought-after examples, independent authentication and documented provenance are important factors.
Why do French Air Force watches interest collectors?
Interest in French military chronographs is based on several factors. The first is historical. Type 20 and Type 21 watches represent a period when mechanical timepieces were useful instruments for certain aviation operations. The second is technical. Hand-wound movements and flyback mechanisms offer horological interest beyond their purely practical function. Finally, the diversity of manufacturers, variations and military assignments makes this field particularly interesting for collectors. However, the value of a vintage example depends on numerous criteria: authenticity, condition, rarity, provenance, functionality and documentation. Simply describing a watch as “military” is not enough to justify its price.
French Air Force watches: an enduring watchmaking heritage
The history of French Air Force watches remains closely associated with the Type 20 and Type 21 chronographs, developed to meet aviation timekeeping requirements from the 1950s onwards. Breguet, Dodane, Auricoste, Vixa and other brands involved in their production represent the main historical names in this field. These watches also highlight an important distinction: an authentic military-issued watch can be traced to an identifiable military supply contract, whereas an aviation-inspired watch may be a commercial or commemorative creation. Today, historical chronographs and their modern reinterpretations continue to illustrate the connections between mechanical watchmaking and French military aviation.
