Genuine complication at a fraction of steel sports-watch pricing.\u003c\/p\u003e\n\u003cp\u003eA 2014 reference 5140P in platinum with a blue dial, perpetual calendar, moonphase, and 24-hour and leap-year indications, driven by the ultra-thin micro-rotor calibre 240 Q. Complete with box, papers, and certificate. There is a persistent irony in the current market: a platinum Patek perpetual calendar — a genuinely difficult mechanical achievement — trades well below a steel sports watch with a time-and-date movement. For a collector buying horology rather than hype, this is the most interesting value in our inventory.\u003c\/p\u003e\n\u003ch3\u003eSpecification\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eReference\u003c\/th\u003e\n\u003ctd\u003e5140P-001\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eYear\u003c\/th\u003e\n\u003ctd\u003e2014\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eCase material\u003c\/th\u003e\n\u003ctd\u003ePlatinum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eCase size\u003c\/th\u003e\n\u003ctd\u003e37 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eMovement\u003c\/th\u003e\n\u003ctd\u003eCalibre 240 Q, automatic perpetual calendar, 48h reserve\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eCondition grade\u003c\/th\u003e\n\u003ctd\u003eExcellent\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eBox \u0026amp; papers\u003c\/th\u003e\n\u003ctd\u003eFull set — box, papers \u0026amp; certificate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eAvailability\u003c\/th\u003e\n\u003ctd\u003eIn stock\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eCondition report\u003c\/h3\u003e\u003cp\u003eCase: excellent platinum case with factory finishing intact and the platinum diamond marker at the six o'clock lug position present.\u003c\/p\u003e\u003cp\u003eBezel: stepped platinum bezel with sharp edges and no polishing.\u003c\/p\u003e\u003cp\u003eCrystal: original sapphire, unmarked; display caseback also unmarked.\u003c\/p\u003e\u003cp\u003eDial: blue dial flawless with crisp sub-dial printing; moonphase aperture clean and correctly aligned; applied gold indices perfectly seated.\u003c\/p\u003e\u003cp\u003eStrap: original Patek Philippe navy alligator strap with light wear at the buckle holes; original signed platinum deployant clasp.\u003c\/p\u003e\u003cp\u003eMovement: calibre 240 Q running +2 seconds per day.

Calibre 240 Q inspected through the display caseback and confirmed by micro-rotor geometry, Geneva Seal markings, and matching numbers. Perpetual calendar advanced through a full simulated cycle including a month-end and leap-year transition to verify correct mechanical behaviour — the single most important functional test on this reference, because perpetual calendar repair is specialist work. Sub-dial printing and moonphase disc alignment examined at 40x.\u003c\/p\u003e\n\u003ch3\u003ePricing rationale\u003c\/h3\u003e\u003cp\u003eThe 5140P is out of production, so no retail figure applies. Completed sales for full-set platinum examples in Excellent condition ran HK$840,000–HK$960,000 over ninety days. We are priced at HK$890,000, mid-band, supported by complete documentation and verified perpetual calendar function. One caution stated plainly: perpetual calendar servicing is specialist work and materially more expensive than a time-and-date movement. Budget for it. In exchange, this reference has held value far more steadily than the steel sports segment through the post-2022 correction.\u003c\/p\u003e\n\u003ch3\u003eService history\u003c\/h3\u003e\u003cp\u003eServiced by a Patek Philippe authorised service centre in September 2025; documentation on file and provided to the buyer.
