Released in 1961, the Patek Philippe ref. 3445 was the firm’s first serially produced self-winding wristwatch with date. Adopting a two-piece screw down case made by master casemaker Antoine Gerlach, the wristwatch is waterproof and was made in several case materials including yellow, white, pink gold and platinum. The calibre powering the reference is the calibre 27-460M (M for Monodate) was an evolution to the 12-600AT used within the 2526, these upgrades includes the Gyromax balance wheel.

While most ref. 3445 remained in production for 21 years, a series of them were made with an integrated bracelet with the absence of lugs on four sides under the ref. 3445/6. Simplistic and extremely elegant, you can find examples in yellow gold, white gold or platinum (rarest) offered with silver, champagne, blue, grey dials, and lastly most sophisticated of all, diamond-set dial where only a handful has ever appeared in the market.

Fresh-to-the-market and extremely well-preserved with a movement number of 1’231’202, this is part of the 2nd series that began production in 1970. According to our research only one example with the same configuration has appeared in the market. It’s understated white gold case is finely finished with a linen-texture that elevates the presence of the ref. 3445/6 and goes perfectly with a linen suit. Crisp hallmark can be seen on the satin-finished caseband, furthermore confirmed by the Patek Phillipe Extract from the Archives, this is a spectacular example from 1971.
