Mathey-Tissot x Massena Lab Type XX Tribute Chronograph honors one of the great tool watches of mid-century aviation.

In the 1950s and ’60s, several prominent manufacturers were issued contracts by the French Ministry of Defense (MOD) to produce pilot’s watches according to certain military specifications. The requirements included a flyback function, or retour en vol, which allowed a pilot to instantaneously restart a running chronograph without the typical need to stop, reset, and then restart.

Mathey-Tissot was one of the most industrious suppliers of the Type 20 chronograph of the post-war era, supplying many of the chronographs to the French government. The Mathey-Tissot x Massena Lab Type XX Tribute Chronograph has a warm, brown, tropical dial and coffee-colored, luminous Arabic numerals. This dial is exclusive to Massena LAB and inspired by William Massena’s very own vintage Breguet Type XX chronograph from his personal collection.
