The crystal has no nonreflective coating and therefore legibility is not always ideal. Luminous material on the hands and on the indexes at 3, 6 and 9 facilitates orientation in the dark. There’s
no date display. Its absence assures a tidy-looking dial, but might dissuade some from buying this model. If you’re one of them, Rolex offers the Datejust in 36-mm and 41-mm versions, each with a
magnifying lens above the date display, and each at a significantly higher price. Fake Watches
With a water-resistance rating of 100 meters, the Oyster Perpetual 39 is well suited for daily use.
Due to the lack of a date display, operating the Oyster Perpetual 39 is refreshingly simple. The crown, which unscrews easily, has only two extracted positions: one to wind the mainspring and
another to set the hands. This model also provides convenient stop-seconds function that halts the balance, and thus also the hands, to facilitate to-the-second time setting.
The horizontal bar under Rolex’s crown-shaped logo on the winding button stands for the Twinlock crown. With a water-resistance rating of 100 meters, the Oyster Perpetual 39 is impermeable enough
for a sportily elegant watch and is well suited for daily use.
The caseback of the Rolex Oyster Perpetual 39 is fully threaded: underneath it is Caliber 3132. It differs from its predecessor (Caliber 3130), which powers the smaller, 36-mm and 34-mm models,
in that it has a Parachrom balance spring and Paraflex shock absorption. (Parachrom is an alloy of niobium and zirconium; Paraflex is a patented, specially shaped shock-absorbing device. Both
were developed in house.) Caliber 3132 is based on the familiar Caliber 3135 with date display, which ticks inside the Submariner and the Datejust.
Each of these Rolex manufacture calibers is a good choice if you want to own just one watch because watchmakers rate all of them among the best automatic movements on the market. They earn this
distinction for several reasons: they’re quite robust; their architecture is designed to maximize longevity; and they can be finely adjusted with extreme precision Breitling Replica. That’s why a sturdy balance bridge takes the place of an ordinary
balance cock, which is borne on only one side. Two knurled screws can be turned to adjust the vertical play. A Breguet terminal curve on the balance spring contributes to precise timekeeping in
every situation, as does the regulator-free fine adjustment mechanism via Microstella nuts on the balance. No matter which way the rotor happens to turn, red anodized wheels in the self-winding
subassembly convey its kinetic energy with minimal friction.
The balance spring is unaffected by magnetic fields. This component is also reputed to be able to cope with shocks and vibrations 10 times more effectively than conventional balance springs. The
Paraflex shock-absorption system also dampers shocks better than standard shock absorbers.
The movement’s engineering and decoration are equally impressive. For example, a handsome sunburst adorns the automatic bridge and the rotor. The latter boasts Rolex’s characteristic piercings.
Other bridges are embellished with circular graining, also known as “perlage.” All bridges and plates are plated with rhodium and their edges are beveled and pol- ished. The polished heads of the
screws look quite pretty, too. Rolex regrettably opted for a solid, not transparent, caseback. It would have offered a lovely view of the mechanisms, while simultaneously making life more
difficult for would-be counterfeiters. Must you be willing to forego a visible movement if you opt for a one-and-only watch? Each potential buyer will have to answer this question himself.
Caliber 3132 is based on the familiar Caliber 3135 with date display, which ticks inside the Submariner and the Datejust.
The rate results clearly show which five positions Rolex used when finely adjusting the watch. The results would have been nearly perfect were it not for the rogue value posted in the uncommon
“crown left” position. If you eliminate this stray number, you’ll come up with a calculated average deviation of zero seconds per day. Even if you include the “crown left” number, the final
results are sufficiently precise.
But what about the price? Debiting $5,700* from your bank account will provide you with the least costly entrée into Rolex’s world of gents’ watches. You’ll have to pay significantly more
($7,150*) for the 41-mm-diameter Datejust II with date display. Our tested watch offers the best cost-benefit ratio of all Rolex models.
Of course, the concept of a “one-and- only watch” is a myth. If you’re like me, you’ll always become infatuated with another watch. You’ll yearn for it and gaze longingly at it until you finally
possess it. But if you were damned to a life of horological monogamy and were permitted to own just one, then the Rolex Oyster Perpetual 39 would be a very good choice – assuming, of course, that
you’re willing to do without a date display or a transparent back. If so, then this model’s go-with-every-outfit-and-every-occasion styling, large-enough-but-not- too-large dimensions, and
robustly well- engineered self-winding movement will ensure that your wrist is well equipped for whatever the day – or the night – has up its sleeve.
