Original Swiss Patek Philippe Calatrava man's wristwatch 18k yellow gold, case measures 32mm in diameter not including the winding crown. Has Patek Philippe extract from the archives dating the original sale of the watch to 1951 Watch works perfectly and keeps excellent time. This is the rarer model with the large center seconds hand and it uses the 27SC movement with the Geneve seals, which means this is the highest quality of watchmaking that exists. The Rolls Royce of Watches. Strap, buckle not original, I have just fitted a new crocodile strap. There is no box but it has the Patek Philippe extract. Would consider a trade for other Rolex watches in any condition. I am a watch repairer and am happy to repair any watch that needs attention.
