On the Wrist:Rolex Oyster Perpetual Yacht-Master Men's Replica

In this feature from our July-August issue, we take a close look at the new version of Rolex Oyster Perpetual Yacht-Master Replica, with black Cerachrom bezel and Oysterflex bracelet. Original photos are by Nik Schölzel.


A water-resistant Oyster case, large hour markers and bold hands are essential elements of Rolex’s Submariner, introduced in 1953 and made for use underwater. In contrast, Rolex’s Yacht-Master, launched in 1992, is a luxury liner – equally at home on board a yacht on the high seas or on land at a ritzy yacht club.

The Rolex Yacht-Master Replica was the first replica watch in Rolex’s Professional Oyster Collection to come in three different case sizes: 29, 35 and 40 mm. The model we tested, launched last year, is offered in two sizes: 37 and 40 mm. We chose the larger version, which we measured at precisely 40.19 mm in diameter and 11.49 mm in height (excluding the magnifying “Cyclops” lens for the date).



The well-known Cyclops date lens was patented by Rolex in 1953 and introduced in 1954 on the Datejust. This magnifying device is made of sapphire, like the replica watch’s crystal, and has nonreflective coating on both sides. The jumping date advances exactly at midnight.


The replica watch is powered by a seasoned caliber, the Rolex 3135, used in the very first Yacht-Master in 1992. The 3135 debuted in 1988 in the Submariner. The blue Parachrom balance spring was added to the movement in 2005, five years after it was first introduced in the Cosmograph Daytona. Its paramagnetic alloy resists changes caused by temperature variations and magnetic fields.

The Parachrom balance spring is thinner than a human hair and up to 10 times more resistant to shocks than a conventional balance spring. Provided with an overcoil, it is attached to a large balance wheel with a variable moment of inertia. Fine adjustments are made using four gold Microstella regulating screws. The balance wheel is supported by a height-adjustable bridge. The entire construction ensures rate results that bring the Yacht-Master (as well as the other replica watches in the Oyster collection) to the rank of “Superlative Chronometer Officially Certified.” These words on the Yacht-Master’s dial mean that the replica watch has endured 15 days and nights of testing by COSC in addition to a series of tests conducted by Rolex in its own laboratory. Acceptable rate results for a Superlative Chronometer allow deviations of less than +/-2 seconds per day, while COSC’s test permits average deviations between -4 and +6 seconds per day. In addition, Rolex’s tests are carried out under conditions that correspond more closely to real-life situations than COSC’s tests and are conducted on fully assembled replica watches, while COSC tests just the movements.


The Yacht-Master’s new Oysterflex bracelet has a core made of nickel – titanium alloy blades, a black elastomer coating and a patented cushioning system inside.

We, too, tested the finished replica watch – fully wound and after running for 24 hours – first in five positions on the timing machine and then with a two-week wearing test on the wrist (or simulated on a winding machine). In our tests, the Yacht-Master remained within the standards specified by Rolex for a Superlative Chronometer. On the wrist it showed virtually no deviations over the two-week period. On the timing machine it showed a gain of about 1 second per day with minimal variations among the positions.

The tests performed by Rolex include a water-resistance check. Unlike the Submariner, the Yacht-Master’s water resistance is “only” 100 meters. This means that the Yacht-Master is not designed to be a professional dive replica watch, which requires water resistance of at least 200 meters.
