Beautiful original Patek Philippe silver dial co-branded Hausmann&Co. this is an extremely fine example of the rare square 3430 from the 1950s. The original dial is in good condition, the case still has sharp edges but does show signs of wear, and the original signed crown also shows slight wear. This watch comes with its original strap and buckle and measures 26mm square which is the perfect size for a square dress watch. And by the way, square is back in style! The watch is hallmarked in all the areas it should be. As the name implies, Cal. 23-300 is 23 mm (10 ligne) in diameter and 3 mm tall. This compact size made it ideal for the popular Patek Philippe Calatrava and similar slimmer watches produced in the 1950's and 1960's.


Cal. 23-300 is classic in layout, with a barrel bridge covering the ratchet and crown wheel, a curved center wheel bridge, and separate cocks for the fourth and escape wheel. It was derived from the preceding Cal. 10-200 but with many modifications. It is notable in that it is equipped with both an overcoil hairspring and a free-spring Gyromax balance, a combination not found in any other 10 ligne Patek Philippe movement.


This movement is greatly respected today, with many saying it is one of the best hand-wound movements ever produced by Patek Philippe. Carlos Perez said about the 23-300, it "represents both the technical and artistic peak of Patek's 10 ligne handwinds, as the 27-AM 400 was the peak of their 12 lignes."


This is a top quality vintage Patek completely unmolested and a fantastic price. Don't let this pass you by; we all know the vintage Pateks are going up double digits each year. Everytime I sell one, it can not be replaced for the same price...sometimes not even close; and any clean watch with the 23-300 is in high demand. 


This sale cannot be combined with any other discount, like coupon codes etc.

The Famous Patek Calibre 23-300

Carlos Perez wrote a comparative essay on some of the famous handwinds and to quote, "The 23-300 is one of very few movements manufactured by Patek Philippe to use both an overcoil hairspring and a free-sprung Gyromax balance, and of which it was the only 10''' handwind. It represents both the technical and artistic peak of Patek's 10 ligne handwinds, as the 27-AM 400 was the peak of their 12 lignes."
