Tudor is renowned for its collaborations with various military forces starting from the 1960s, supplying Submariner models specifically designed for military use. Among the most notable units that adopted Tudor watches as official equipment are the Comsubin, the Argentine Marine Infantry Corps, the Israeli Defense Forces (IDF), and, of course, the French Marine Nationale.
This watch is a Tudor Submariner ref. 9401/0 with a blue dial and bezel, an example that was indeed issued to the Marine Nationale. Its assignment dates back to 1982, as engraved on the caseback, one of the final batches supplied to the French Navy.
This particular example features a dial with round “dot” indexes and Mercedes hands, characteristics typical of the last versions delivered to the Marine Nationale, replacing the earlier “Snowflake” configuration.
Despite its use in military environments, the watch remains in exceptional condition: the dial, hands, bezel, case, and movement are all perfectly preserved. The caseback engraving, sharp and well-defined, confirms its authenticity and official issue.
All components, including the dial, bezel, hands, movement, and caseback, are correct for the production period and consistent with a Tudor MN 9401/0 issued in 1982.
Inside the caseback are several service markings, including one performed in Geneva at a Rolex service center, a detail that further enhances the desirability and collectability of this Tudor 9401/0.
This is a fully original and period-correct example, rich in historical and military significance, and an essential piece for any collection of military-issued dive watches.
