We are so pleased to offer this incredible stainless steel Patek Philippe Calatrava reference 2508, manufactured in 1963. This reference is more common in gold and highly collectible and much more rare in stainless steel. The water resistant stainless steel case is super strong. The pristine original silver dial is gorgeous with applied steel markers and sweep seconds hand. This beauty is powered by a caliber 27SC manual wind movement. This watch comes on an extendable stainless steel Guy Freres Rivet Oyster bracelet. According to the Archive, which will come with the watch, it was manufactured and also sold in 1963.
