Rolex Oyster Perpetual & Rolex Submariner

If you think that Rolex’s innovation means a revolution, you are wrong. But the Submariner has been modified in such a way that the sum of its various details makes a new watch. The diameter of the watch has increased from 40 mm to 41 mm, or more precisely, from 40.6 mm to 41.36 mm, measured diagonally from 2 to 8 o’clock. The crown guard and lugs are thinner, but this increases the width of the lugs by a full millimeter to 21mm.
These seemingly minor upgrades change the proportions of the entire watch – including the body of the case, the bezel, the dial and the strap. This means you’re looking at an entirely new model. If you put the new replica Rolex Oyster Perpetual Submariner next to its predecessor (which is being discontinued), the changes become obvious. The new Submariner looks more than a millimeter larger than the old model, thanks to extensive modifications to the tiniest of details.
Less obvious is the new in-house self-winding movement, caliber 3230, because like any Rolex watch, it is covered by a finely slotted case back that is tightened airtight with a special key and can only be opened by an authorized Rolex watchmaker. The 3235 caliber differs in that there is no date display on the Submariner’s dial.
Otherwise, all other functions are the same. The new Submariner is equipped with the innovative Chronergy escapement patented by Rolex and made of nickel-phosphorus alloy. It offers exceptional functional reliability and high energy efficiency and is resistant to the effects of magnetic fields. The movement is also equipped with an optimized version of the Rolex Parachrom hairspring.
Rolex produces the hairspring in-house from a paramagnetic alloy, which makes it 10 times more accurate than a conventional hairspring. It also has a special Rolex overcoil that ensures a constant rate in all positions. The oscillator is supported by the excellent patented Paraflex anti-vibration system designed by Rolex. Thanks to a more efficient escapement and barrel design, both the caliber 3230 and the caliber 3235 have a 70-hour power reserve. In addition to the COSC chronometer test, the watch must also pass Rolex’s rigorous in-house “Super Chronometer” test, which allows a deviation of no more than 2 seconds per day, according to the norms in force since 2015.
