Rolex Submariner

The new Oyster Perpetual Submariner Date from Rolex is an update to the previous Submariner Date released about a decade ago. The case has undergone an update and is now 41mm in diameter vs. the previous 40mm case. In addition the caliber has been updated from the 3135 to the 3235 giving the 2020 Rolex Submariner a much more robust power reserve of 70 hours, up from the previous 48. Not just a clever name, the Rolex Submariner boast an impressive waterproofness of up to 300 meter or 1,000 feet.
