Rolex will still be sending all 3255 movements for official replica watches
certification at COSC, who tests the uncased movements for an accuracy of -4 / +6 seconds per day. Rolex receives the replica watches
certified movements, cases them up, and then submits the fully assembled watches to its own in-house tests which will guarantee that the Rolex Day-Date 40 (and probably other models down the line) are accurate replica watches sale
within the aforementioned rate of -2 / +2 seconds per day. The testing is done by Rolex's specially replica watches
programmed high-technology equipment and an exclusive methodology that simulates the conditions in which a watch is actually worn. That likely includes the simulation of how the watch takes up countless different replica watches
positions when worn on the wrist every day, how it is subjected to sudden moves, and also probably of how the watches remain stationary for 8-10 hours each day, when they are not worn.
