Patek Philippe

A rare one it seems as I believe less than a few hundred in any metal of this reference were produced in the mid to late 50s. The likes of the 2526 actually made in larger numbers, around 2000. Only a few 2583 seem to have turned up at auction these last ...  

Concerning ref. 2583 in yellow gold, according to Christie’s back in 2010 only 7 had appeared in public: https://www.christies.com/en/lot/lot-5367877 Also you might enjoy if you don’t know it this article on the 12-600: https://goldammer.me/blogs/articles... 

Thanks so much, will check out!

So it does appear to be one of the rarer of the 12-600 references and I can’t find any hits based on serial and case no.

interesting side profile 👍 Regarding the PP logo on the crown, when did it disappear ?

I think around late 1950s but others will know better than me! Thanks for comments!
