With a total production of 237 examples, it was manufactured in yellow or white gold and represents one of the most interesting perpetual calendar ever created by Patek. While physically similar to reference 3448, it most notably features a leap year indicator on the dial. In addition, its case back is slightly smaller and is fitted with a “tongue”, enabling it to be easily removed by the wearer. Towards the end of production in 1985, a very few examples (no more than two dozen) were fitted with a sapphire crystal back and given the reference 3450-100. Offered at auction, the present watch is a wonderfully preserved example of this very rare to find reference 3450 which was discontinued over 37 years ago. The present watch, manufactured in 1982, is among the last generation of reference 3450s ever made before the introduction of reference 3940. While the first generation examples were fitted with a “red dot” to indicate the fourth leap year, second generation examples displayed Roman numbers I, II, III and IV, like the present model. Lightly worn, it reveals the full potential in size and beauty this reference can offer,bining substantial lugs with sharp and clean lines and the still legible hallmarks on the case. Further evidence of carefulness of preservation is the presence of the original warranty and fitted presentation box.Estimate € 220000 - 440000A 20% import VAT is due on the final price including , only if it is delivered within the EU
