IWC Portuguese Perpetual Calendar Watch

The IWC Portuguese Perpetual Calendar, the first perpetual calendar replica in the replica watch market, uses an upgraded 52610 movement based on imported Grand Seiko movements. It not only achieves most functions of the perpetual calendar with stability in timekeeping but also boasts an extremely low repair rate, making it one of the toughest and most complex functional replica watches in the market.

Reasons to acquire:

1. **Perpetual Calendar**: The perpetual calendar year indicator at 8 o'clock operates normally (2017-2024, with the option for a free factory replacement of the year module in 2024). Like the original, it can be adjusted via hidden buttons on the case, and it surpasses the original with reversible adjustment (the original requires paid repair if the year is adjusted beyond its limits).

2. **Date, Moon Phase, Day**: The date (at 3 o'clock), month (at 6 o'clock), and day (at 9 o'clock) all function correctly and can be manually adjusted (date via the second position pull-out bidirectional adjustment, month via hidden button adjustment at 8 o'clock, and day via adjustment by moving the hands).

3. **Exquisite Craftsmanship**: Meticulous craftsmanship both inside and out, with German CNC machining for case and bracelet molds, followed by individual quality control checks. The brushed and chamfered finishes on the case nearly match those of the original, with synchronized font distribution on the movement and delicate polishing of fish scales and other textures. It features an arched scratch-resistant sapphire crystal that matches the transparency of the original.

4. **Elegant Fit**: Dimensions of 41mm x 13mm make it more suitable for Asian wrists, with a versatile and elegant case shape that exudes gentlemanly qualities, as seen on celebrities like Chen Bo-lin and Zhang Ruoyun.

5. **Stable Movement**: The Grand Seiko movement inherently has minimal error and is stable. Moreover, after successful assembly, every completed watch undergoes a day-long simulation test on Swiss-imported QE simulators. Only watches that show no errors or stoppages are shipped out. This makes it historically one of the most complex and stable watches in the replica market.
