Released in 2005, the Patek Philippe Annual Calendar ref. 5146J is a modernised version of its predecessor, the ref. 5035, with an updated 39mm case design that is classical in its styling with a round shape, domed bezel, undulating lugs and polished surfaces. Standing at just 11.5mm thick with gently sloped lugs, the ref. 5146J wears comfortably as its profile hugs the wrist allowing its leather strap to comfortably drape over and close with its fold-over clasp. Perhaps the ref. 5146J’s most distinguishing feature, which is the reference we have here, is its beautiful and distinctive slate grey dial. Modernising the ref. 5035’s Roman numeral dial in lieu of a design that has remained in style today, the ref. 5146J features applied Arabic numerals at 3, 9 and 12 with stick indices elsewhere blending legibility with a clean aesthetic to match its otherwise clutter-free dial. Intelligently laid across its slate dial, the ref. 5146J houses two sunken subdials at 3 and 9 o’clock with the day and date displays and a subtle power reserve indicator at 12 o’clock with a moon phase display mirroring it at 6 o’clock rounding off an incredible symmetrical case design with an equally symmetrical dial layout. Powering by the automatic cal. 324 S IRM QA LU, which is proudly displayed behind its exhibition caseback, the ref. 5146J boasts Patek’s renowned finishing that tops off this wonderfully designed timepiece and serves as a reminder as to why Patek Philippe is so highly regarded as the world's premiere watchmaker.

A well-thought-out and carefully crafted timepiece that showcases Patek Philippe's attention to detail, it is timepieces like the ref. 5146J that proves why Patek's craftsmanship is as revered as it is.
