The world of watches and diving have been united over the decades, and choosing the ideal model for our adventure is usually not a simple decision, especially when they offer us such exquisite machinery, and in this case, Rolex is your choice and its own competitor.
Lovers of the deep have a special connection with the watchmaking house of Rolex, not for something, this brand has strived to surpass itself year after year in the field of diving, which has resulted in two iconic models in this regard, the Rolex Sea-Dweller and Rolex Submariner, but which is the best option?
If it is our first time acquiring a watch of this type, at first glance they are two identical pieces, however, when we know the details, we will verify that they are two different models.
Their peculiarities
In essence, these two models share some characteristics, such as the movement, since both models use the Rolex Caliber 3135 of 31 jewels, to show us the hour, minutes, and seconds, in addition, they both mark the date through a window, up to here, We could swear that we are looking at the same timepiece.
Although there are slight differences, initially, the first is found in the power reserve, which for the Sea-Dweller 4000 is 50 hours, while for the 43 mm Sea-Dweller version, it is 70.
Both presented to the market the black bezel called Cerachrom, a Rolex patent, it is a durable and scratch-resistant hardened ceramic, as well as anti-corrosion properties and high durability to UV exposure, reducing the speed of color fading.
