Swiss watch manufacturer Patek Philippe’s new Reference 5320G Perpetual Calendar attracted a lot of attention at the Baselworld 2017. The timepiece automatically indicates months with 28, 30, and 31 days and every four years also recognizes the 29th of February as a leap day, but it the pure vintage appearance that makes it so special. A lot of the elements of the Perpetual Calendar are proper vintage Patek from the 1940s and 50s, the highly sought after collectors’ watches that rarely show up at auctions. The layout of the timepiece is reminiscent of the Ref. 2497, so are the windows for day and month and moonphase aperture with date.
Applied gold Arabic numerals and sharp-tipped luminous hands (a reminiscence of the Ref. 1463 chronograph from the 1950s), a slender sweep seconds hand, and the crisply graduate seconds scale assure excellent legibility. The case has step details on the bezel and case-mid right down to the grooved lugs, which looks like a combination of ref. 3449 and ref. 2405. The timepiece is driven by the calibre 324 S Q (S stands for seconds, Q for quantième perpétuel). The moon phases will require a correction by one day only every 122 years and the power reserve is minimum 35, maximum 45 hours. The vintage-style case is 40mm in diameter and available in only 18K white gold. The Perpetual Calendar arrives on a shiny chocolate brown alligator strap with large square scales secured with a deployant buckle in white gold and is priced at $82,784 USD.
