The reference 3445 was introduced in 1961 as the first mono-date self-winding waterproof wristwatch produced by Patek Philippe. Spanning twenty years of production, approximately a few thousand timepieces were manufactured and featured a variety of Sterns Frères dial from silvered, blue and grey, along with a few very rare examples with diamond-set numerals. The two piece Antoine Gerlach and later Pugin Marcel case was made in all four metals and produced in three series the first, like the present watch with the movement numbers from 1’11x’xxx to 1’12x’xxx, the second series bearing movement numbers 1’23x’xxx from the late 1970s and featured a higher bezel to accommodate the sapphire crystal and the last series with a sapphire crystal display back.

The present watch is in lovely overall condition with sharp edges and a clean dial fitted with sought after pearl hour markers. The model has and classic appeal that is as modern today as it was in 1960.
