Lastly, both the 16613 and the 116613 are fitted with stainless steel and 18k yellow gold Oyster bracelets. Depending on the year released, the ref. 16613 has either solid or hollow end-links, either a stamped or link-style fold-out extension system, and either a gold-through or an all-steel clasp. Collectors have different preferences on 16613 bracelet styles, making it a fun watch to collect.The ref. 116613 offers a more substantial hold on the wrist than its 5-digit predecessor and features solid gold center links, solid end-links, and a machined Oysterlock clasp with an innovative Glidelock extension system. The solid construction of the bracelet balances the Super Case nicely on the wrist for a supremely comfortable hold, even over wetsuits.While the ref. 116613 is noticeably more modern in appearance, it still boasts many similarities to the ref. 16613 in the form of a versatile two-tone finish, similar dial and bezel color options, the same water-resistance of up to 1,000 feet (300 meters), and an Oyster bracelet that wears comfortably and allows for tool-free adjustment over wetsuits. When collecting, it ultimately comes down to preference; do you prefer a classic or a contemporary dive watch?The Rolex Sea-Dweller Deepsea is the most robust and over-engineered dive watch in Rolex’s current lineup. While the regular Sea-Dweller is water-resistant to an insane depth of 4,000 feet, the Deepsea has an absolutely abyssal depth rating of 12,800 feet, which is more than 100 times further below the surface of the ocean than any human could physically survive.Although the case of the standard Rolex Sea-Dweller is not all that different from that of a Submariner, the Deepsea has a re-designed case architecture that allows it to stand up to the crushing pressures found at 12,800 feet below sea-level. As a result of its more rugged and highly specialized build, the Deepsea is among the largest Rolex watches currently in production, with a case diameter of 44mm, and an overall thickness of just under 18mm.
