The reference 2509 is also known as 'Grande Calatrava Waterproof' and was launched in 1950 alongside its sister reference 2508. The two differ by having either sweep seconds or subsidiary seconds such as the present watch. Reference 2509 was produced until at least 1967 and only around 20% of the production was cased in pink gold such as this lot.
