Omega Planet Ocean Case and Rolex Cas

Absolutely, the case of the 43mm Sea-Dweller is an Oyster case, world-renowned for being the first water-proof watch case of its kind. The Oyster case is used across most of the Rolex line, from its traditional Datejust to its various sport and tool watches, and it is known for its screw-down winding crowns and case-backs. The case of the Sea-Dweller is also particularly designed to withstand the depths of the ocean, giving the wearer 4,000ft of water resistance and boasting an automatically-operated helium escape valve. You will also see that on today’s Sea-Dweller watches, the sapphire crystal features a Cyclops magnification lens over the date window. Today, the 43.5mm Omega Planet Ocean 600m we’ve been concentrating on is only available in stainless steel. However, there are two versions that boast Cal. 8901 movements, which are forged out of 18k white gold or Sedena gold. It’s also crucial to note there are other sizes available for the Planet Ocean collection. The standard size is 43.5mm and this is also the only size available for the different GMT models replica watches. However, Omega also gives a smaller 39.5mm version of the Planet Ocean, along with a chronograph version that has a 45.5mm case.
Today the Rolex Sea-Dweller is available in both Oystersteel and Yellow Rolesor. The introduction of the two-tone Sea-Dweller model is quite new, only having been released in 2019. This was a great upgrade for the luxury sports watch, as it had been viewed as a flat-out tool watch since its initial introduction and had never before been offered with the option of precious metals. However, as an inherent luxury watch, it made sense for the iconic Swiss manufacturer to incorporate 18-karat gold into its design. Stainless steel and two-color versions of the Rolex Sea Resident clock at 43 mm.
