Along with our colleagues,the Monochrome team also spent a busy week at Baselworld 2014, and had the chance to see and review a number of the Newest Replica Watches for UK Sale introduced at the fair. In this article, we take a closer look at the Rolex Sea-Dweller 4000, a highlight piece for many Rolex fans.

To be honest, we have missed the Sea-Dweller over the past six years. After the introduction of the Rolex Sea-Dweller Deepsea in 2008, the existing reference 16600 Sea-Dweller disappeared from the collection. That was one of the reasons to include it in the wish list that we published a few weeks before Baselworld. After several years of absence from Rolex’s collection, the Sea-Dweller is back in a contemporary version, featuring a Cerachrom bezel insert, the Oysterlock safety clasp and the Rolex Glidelock bracelet extension system.

Besides the re-introduction of the Sea-Dweller, we also predicted (and wished for) a GMT-Master II with a blue/red bezel (nicknamed “Pepsi”), a Daytona with a silver dial and black chronograph subdials (nicknamed “Panda dial”) with black ceramic bezel, and a Milgauss with a blue dial. Rolex delivered on the Milgauss and GMT-Master II Pepsi, though not the Daytona. Fortunately, the world’s most iconic dive Top Replica Breitling Watches is now available again.

The Rolex Sea-Dweller was introduced in 1967 and was originally designed for professional deep-sea diving. It already featured a helium escape valve – something that Rolex patented in 1967 – which is a useful item for professional divers, who have to stay in diving bells for a period of time. At the depths where diving bells are used, divers do not breathe the same air that we breathe on the surface, as that would be dangerous (some gasses expand in such way that they would damage our body when ascending). That’s why professional divers use a gas-mix that also includes helium. Unfortunately helium can enter a dive watch (when the pressure is very high, like in great depths), and when the diver ascends the helium molecules expand faster than they can escape from the watch’s insides. The resulting pressure from the inside might ultimately pop the watch’s crystal out — something you really don’t want to happen!

You need to take into account that when the Sea-Dweller was introduced, mechanical dive watches served a real purpose — unlike today, when probably 99 percent of these dive watches see no action other than “desk diving.” Back in the 1960s and ’70s, there were no electronic dive computers and a Fashion Replica Watches UK, with unidirectional rotating bezel, was a life-saving instrument.
