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

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

Its angular case has an ultra thin 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 fully Patek parts down to the hands and winding crown.

Its presents beautifully on the wrist. Its case is in very good condition. Its silver dial has just been restored by one of the leading dial experts in North America.

One of our watchmakers has disassembled it down to its last screw and cleaned and oiled it. It is running very strong and true, keeping time on par with a brand new Patek in our testing position.

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

Accompanying the watch is an Extract from the Patek Philippe Archives attesting to its authenticity and originality. The Extract costs 500 Swiss Francs (approximately $550 USD) to obtain. Patek has confirmed with us it will be issued, and we will add a photo of it to the listing once it arrives from Switzerland.

Included with the purchase is a one-year C.O.T. international warranty on the movement and its function, a full-page custom printed Connoisseur of Time Certificate of Authenticity, and a new timing certificate attesting to its performance.
