We are pleased to offer the very fine and all-original Patek Philippe mens ref. 3430 Gondolo square watch showcased in today's offering.

With its understated silver face and timeless angular case, it showcases a classic and elegant Patek style. Its angular case has an extra slim profile from the side.

The ref. 3430 was introduced to the market in 1958 and stayed in production until the early 1970s.

Powering the watch is its illustrious Patek Philippe 10 ligne movement, stamped in two places with the prestigious Poinçon de Genève, unquestionably among the finest hand-winding movements ever built. Photos of the inside available upon request.

It has all of its original Patek parts and presents beautifully on the wrist. Its case presents as better than near mint with only light wear. It has not been recently polished and retains strong lines.

Its untouched original dial is just short of perfect mint.

One of our watchmakers has disassembled it down to its last screw and cleaned and oiled it. It is running extremely strong and true, keeping time on par with a 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.

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. Also accompanying the watch is a Certificate of Authenticty from eBay and their new professional watch authentication team.

Please inquire if you would like us to obtain an Extract from the Patek Philippe archives for you. Patek charges 500CHF to provide one.
