V9 IWC Portuguese Series Authentic Perpetual Calendar, the first perpetual calendar replica in the replica market. Based on an imported high-precision movement, it has been upgraded to a replica of the 52610 movement. Not only does it achieve most of the perpetual calendar functions, but it also offers stable timekeeping with an extremely low return rate. This is a rare, durable complex-function watch in the replica market.Reasons to Own: 1. 【Perpetual Calendar】— The perpetual calendar year at the 8 o’clock position operates normally (2017-2024; free factory replacement of the year module available in 2024). Like the original, it can be adjusted via the hidden pushers on the case. It surpasses the original by allowing bidirectional adjustment (the original year cannot be reversed; over-adjustment requires paid repair).2. 【Date/Month/Day】— Date (3 o’clock), month (6 o’clock), and day (9 o’clock) all function with normal gearing and can be manually adjusted (date via bidirectional adjustment in second position, month via hidden button at 8 o’clock, day by moving the hand);3. 【Exquisite Craftsmanship】— Meticulous inside and out. Case and bracelet molded with German CNC equipment, followed by individual manual QC. Every sandblasted finish and chamfer rivals the genuine article. Movement text layout mirrors the original, with exquisite fishscale and other engraving details. Domed scratch-resistant crystal offers identical clarity to the genuine piece.4. 【Elegant on the Wrist】— Dimensions of 41mm x 13mm suit Asian wrists perfectly. The case design is versatile and refined, exuding gentlemanly charm. Same model worn by Chen Bolin and Zhang Ruoyun.5. 【Stable Movement】The Seiko movement inherently boasts minimal and consistent accuracy. Beyond this foundation, every finished watch undergoes a full day of simulated testing on a Swiss-imported QE simulator. Only models showing zero deviation or stoppage are released—making this the most complex and stable replica ever produced. V9Factory creates miracles, starting from the very core.Every V9 watch comes with a built-in remote anti-counterfeiting chip in its packaging, ensuring buyers purchase with confidence and preventing unscrupulous vendors from passing off inferior products as genuine.
