The annual calendar itself — a Patek invention of 1996 — represents one of the maison's signature contributions to modern watchmaking, automatically accounting for months of thirty and thirty-one days while requiring correction only once a year. For collectors, the reference offers a compelling balance: the everyday wearability and unmistakable identity of the Nautilus combined with a genuinely useful complication, executed in steel and offered on a leather strap rather than the familiar integrated bracelet.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe 40.5mm case in stainless steel measures 11.3mm thick, retaining the signature rounded octagonal bezel with alternating satin and polished finishes. The sunburst charcoal grey dial with black-gradient rim carries horizontal embossing, white gold applied baton markers, and luminescent hands, with day, date, and month apertures beneath twelve and a combined moon phase and 24-hour subdial at six. The self-winding Caliber 324 S QA LU 24H\/303, visible through the sapphire caseback, delivers a 45-hour power reserve, completed by a black alligator strap with fold-over deployant clasp.\u003c\/p\u003e\n\u003cp\u003e*This timepiece comes with a stylus.\u003c\/p\u003e","brand":"Patek Philippe","offers":[{"title":"Default Title","offer_id":44525668434164,"sku":"P4285S","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0266\/7141\/5373\/files\/patek-philippe-nautilus-5726a-001-annual-calendar-moon-phases-2024-patek-philippe-1200431111.jpg?v=1761765449","url":"https:\/\/wristaficionado.com\/products\/patek-philippe-nautilus-5726a-001-annual-calendar-moon-phases-1","provider":"Wrist Aficionado","version":"1.0","type":"link"}
