Patek Philippe Annual Calendar 5146J 010 Slate Grey Dial in 18k Yellow Gold

There is something particularly appealing about the combination of warm yellow gold and a deep slate-grey dial. On this Patek Philippe Annual Calendar, the contrast gives a traditional complicated dress watch a wonderfully contemporary character. Add the beautifully shaped case, the balanced dial layout and one of Patek Philippe's most practical complications, and you have a watch that feels special without being overly formal. Introduced in 2005, the reference 5146 brought Patek Philippe's Annual Calendar into a more contemporary 39mm case. This example features a beautifully executed 18k yellow gold case with elegant curved lugs and a distinctive stepped bezel. Particularly pleasing are the well-defined case details and crisp gold hallmarks, complemented by a charming natural gold patina around the back of the lugs. The slate-grey sunburst dial is a real highlight. Applied gold Arabic numerals and hour markers contrast beautifully with the dark background, while the recessed day and month registers, moon-phase display and power-reserve indicator give the dial plenty of depth and character. Despite all this information, the overall design remains wonderfully balanced. Through the sapphire exhibition caseback, you can admire the beautifully finished automatic calibre 324 S IRM QA LU, complete with its decorated 21k gold rotor. The watch and movement have been fully serviced by an experienced professional watchmaker. We have paired this fine Annual Calendar with a grey Bulang & Sons leather strap and an original Patek Philippe 18k yellow gold folding clasp. The watch is accompanied by a Patek Philippe leather travel pouch, two gold spring bars and the original Beyer Chronometrie invoice from Zurich, documenting its sale in May 2015. We love the understated character of this combination. Warm yellow gold, a beautiful slate-grey dial and a genuinely useful complication. An elegant Patek Philippe with real personality and the kind of proportions that make it a pleasure to wear.

The mechanism automatically accounts for months of 30 and 31 days, requiring only one manual correction each year, at the beginning of March. The reference 5146 followed in 2005, introducing a larger, more contemporary case, a redesigned dial and the addition of a moon-phase display. It remains a wonderful example of Patek Philippe's ability to combine traditional watchmaking with everyday practicality.
