Catalogue Essay
Reference 2509 was launched in 1950. This particular example is fitted with the highly unusual anti-magnetic caliber 27 AM 400, which was launched in 1960 and was usually reserved for other references besides the reference 2509. There are believed to be less than 10 examples known. The reference 2509 is a very popular reference due to its sporty design with water-resistant-type case with a screw back. The present watch has been preserved in a lovely and original condition.

For collectors, key models include the reference 1518, the world's first serially produced perpetual calendar chronograph, and its successor, the reference 2499.
