Oyster Perpetual Date

The replica Rolex Oyster Perpetual Date we built reconstructs the core of the calendar watch according to Swiss watchmaking standards. The classic replica is equipped with a customized 3135 automatic movement. Through the swing frequency of 28,800 times/hour and the Paraflex shock absorption system, the daily error is compressed to within ±3 seconds, and the triple-lock waterproof structure of the Oyster steel case and the Cerachrom ceramic bezel laser etching process are restored simultaneously. Another series of ‌Rolex Oyster Perpetual Date replica‌ focuses on precious metal versions. For example, the 18K Everose gold watch uses a five-axis CNC engraved triangular grooved outer ring with a thickness tolerance of ≤5 microns, a sapphire mirror coated with a double-layer anti-reflective film, and the calendar window is implanted with a Cyclops lens magnification system consistent with the original factory to achieve millimeter-level visual alignment of the date display.

In order to reproduce the reliability of the “benchmark of calendar watches”, the replica Rolex Oyster Perpetual Date performs four rigorous tests: the screw-in bottom cover has a built-in double silicone sealing ring, which has passed 12,000 pressure cycles and the waterproof depth exceeds the ISO 6425 standard of 150 meters; the bracelet is equipped with an Easylink fine-tuning device, and the deformation resistance of the links is verified by an 8-ton tensile machine. The advanced version is equipped with an anti-magnetic soft iron cover that can withstand 15,000 Gauss magnetic field interference. The instantaneous jump calendar module still maintains a synchronization accuracy of ±5 minutes in the laboratory simulating 30 years of day and night switching. Each watch must undergo -40℃ extreme cold start, 55℃ damp heat aging and 20-direction impact tests.
