Patek Philippe Reference 5204 A pink gold perpetual calendar split seconds chronograph wristwatch with moon phases, leap year and day and night indication, Circa 2017 百達翡麗 型號5204 粉紅金萬年曆追針計時腕錶，備月相、閏年及晝夜顯示、約2017年製 Dial: silvered Calibre: cal. CHR 29-535 PS Q mechanical, 34 jewels Movement number: 5'252'873 Case: 18k pink gold, screw down sapphire crystal display back Case number: 6'147'070 Closure: brown Patek Philippe alligator strap and 18k pink gold folding clasp Size: 40 mm diameter Signed: case, dial and movement Accessories: Patek Philippe Certificate of Origin, additional case back, setting pin, instruction manual, leather portfolio, photograph and presentation box 附帶證書、備用錶背蓋、調校筆、說明書、皮製檔案夾、照片及盒子Launched in 2012, the reference 5204 is the successor of the reference 5004, both exhibiting a perpetual calendar and split seconds chronograph. Comparing these two references together, one can easily recognize the inspiration of reference 5004 on reference 5204, but with the latter displaying a handful of upgrades while conveying its own merits. To house the 29 mm movement CHR 29-535 PS Q, reference 5204 expands the case to 40 mm in diameter, significantly increasing its presence but still retaining the traditional look. This in-house movement features a double column wheel design with a horizontal clutch, increasing the stability of the watch while reducing the thickness. Perhaps the most distinguishable icon of the reference is its inverted moon phase, making it rather charming and aesthetically pleasing.
