  • Catalogue Essay

    Reference 3450 can unarguably be considered a pinnacle of Patek Philippe production, both aesthetically and technically.

    An evolution of reference 3448 (first launched in 1962), it was released in 1981 and remained in production for a much shorter time than its sibling: only 5 years - until 1985. Such a short run dictated a very scarce output, with a total of 244 pieces made. The main difference with its predecessor is the introduction of the enormously useful bissextile year indication. Until then, perpetual calendar Patek Philippe wristwatches did not have any indication for the leap year cycle: the only way to discover “when” one is in the cycle is to use the correctors to advance to February 28, and then manually advance the hands to see if the date jumps to February 29 or March 1.

    While the dial design is virtually identical to the last series of reference 3448, the case presents a number of minor updates which perfect the architecture of the already acclaimed reference 3448: a metal “tongue” is now present in the back for easier back removal and the overall back architecture is more convex. There is no more bevel to the underside of the lugs - streamlining the overall looks of the case - and the crystal is now sapphire (actually, a detail already introduced in the very last examples of reference 3448).

    The movement is simply a masterpiece, and the culmination of a journey of technical refinement which began in 1953, with the launch of cal. 12-600 AT. Housed in now-classic references (most notably, ref. 2526), it is considered by many as one of the most perfect and lavishly finished automatic movements ever designed. Cal. 12-600 AT underwent an evolution over the years with minor upgrades, the result of customer and “real world” feedback. Once Patek Philippe deemed to not be able to improve the caliber anymore, they changed its name - probably to underline the technical “finality” of the design - and renamed it, indeed, 27-460 at the end of the 1950s. This would form the base of the movement inside reference 3448 (renamed 27-460 Q, for Quantième) and eventually become cal. 27-460 QB (Quantième Bissextile). The automatic perpetual calendar successor to reference 3450 is reference 3940, which however features a completely different dial layout and movement.

    The present example of this historical reference was of course retailed by Beyer, and it is offered in exceptional condition of both dial and case. Most notably, the lightly hand-engraved Beyer number (underneath the top left lug) is still present an unmolested, indicating beyond any doubt the case never suffered aggressive or improper polishing. It is interesting to note that another Beyer-retailed 3450 was sold by Phillips in Hong Kong in 2018, bearing a movement number only 49 numbers away from the present watch. In total, only circa a dozen Beyer-retailed 3450 are currently known from the market, including this example which has never before appeared on the auction market.
