Starting in 2020, the fake Rolex Oyster Perpetual Submariner without date, which many see as the quintessential dive watch, is slightly larger and has an updated movement, yet remains true to its original design. This is our first encounter with the new watch. 
We had to wait a long time for the latest Rolex innovation of 2020. Rolex launched the new generation of Oyster Perpetual Submariner and Submariner Date watches in September. These timepieces are slightly larger and now feature new movements – the Submariner has the recently introduced Caliber 3230, while the new Submariner Date version uses the Caliber 3235 for the first time. The Submariner Date offers a surprising array of color combinations, while the absence of a date display The Submariner Date offers a surprising array of color combinations, while the Submariner without a date display keeps its original design. We were able to preview the new Submariner shortly after its launch. 
If you thought Rolex’s innovation meant a revolution, you were wrong. But the Submariner has been modified and the sum of its various details has resulted in a completely new watch. The diameter of the watch has grown 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 slimmer, but this increases the width of the lugs by a full millimeter, to 21 mm.
These seemingly minor upgrades change the proportions of the entire watch – including the case body, bezel, dial, and bracelet. This means you’re looking at an entirely new model. If you put the new 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, due to the extensive modifications made to the tiniest of details.
Less obvious is the new in-house self-winding Caliber 3230 movement, because like any Rolex replica watch, it is covered by a fine groove that screws down airtight with a special key that can only be opened by an authorized Rolex watchmaker. The difference with the 3235 movements is that the Submariner dial does not have a date display.
