We are pleased to offer the very fine and pleasing all-original Patek Philippe mens ref. 3503 square watch showcased in today's offering.

With its understated champagne face and timeless square case, it showcases a classic and elegant Patek style.

Its angular case has an extra slim profile from the side.

Powered by a Patek Philippe caliber 175 handwound movement, the company's first ultra-thin mechanism, the watch excels in technical merits. This illustrious movement was awarded the prestigious "Geneve Quality Seal" and this example is stamped in two places with it. Photos of the inside available upon request.

It has all of its original Patek parts and presents beautifully on the wrist. Its case is in very good condition. Its champagne dial is original and untouched. Please inquire if you would like it restored.

One of our watchmakers has disassembled it down to its last screw and cleaned and oiled it.

For the finishing touch we have equipped it with a brand new Teju lizard strap making it ready for immediate enjoyment.

Accompanying the watch is a Certificate of Authenticty from eBay and their new professional watch authentication team. We are also happy to provide a Connoisseur of Time Certificate of Authenticity if you would like. Please inquire if you would like us to obtain an Extract from the Patek Philippe archives for you. Patek charges 500CHF to provide one.

Included with the purchase is a one-year C.O.T. international warranty on the movement and its function and a new timing certificate attesting to its performance.
