專家說明
With Patek Philippe Extract from the Archives confirming production of the present watch with amagnetic movement in 1968 and its subsequent sale on 30 October 1969.
This watch is believed to be the only example of a reference 2509 in stainless steel with calibre 27-AM 400 known to date, furthermore preserved in very good, original overall condition.
The particularity of the present reference 2509 is the highly unusual use of a 27-AM 400 antimagnetic movement, normally reserved for Patek Philippe's "Amagnetic" watches such as references 2570/1 and 3460, amongst others. The amagnetic calibre 27-AM 400 was launched in 1960 and is an improved version of the 1958 calibre 12'''400, fitted now with a Gyromax balance and free sprung self-compensation Breguet overcoil hairspring.
"Amagnetic" watches were designed for use in areas of high electro-magnetic fields such as laboratories or electro-engineering. It can therefore be assumed that the original owner of this watch ordered it purposely with an amagnetic movement, as confirmed by both the Certificate of Origin and the Extract from the Archives.
Reference 2509 was launched in 1950 and fitted with the regular calibre 12'''400. Mainly available in gold, the model is distinguished by its sporty design and the water-resistant-type case with screw back.
