At the heart of the Deepsea’s case is Rolex’s patented Ringlock system, which uses a super hard, nitrogen-alloyed steel central ring to internally support both the extra-thick sapphire crystal and the Grade 5 titanium caseback. While the Ringlock system is largely responsible for the overall increase in the case size of the Deepsea, it actually enables the watch to be smaller than it otherwise would be, had it were to follow a more traditional case design while still retaining its same colossal depth rating.The primary purpose of the Ringlock system is to reduce the amount of stress placed on the case of the watch. As pressure on the watch increases at greater depths, the majority of it gets exerted on the front and back surfaces of the watch. Since the nitrogen-alloyed stainless steel compression ring internally supports both the crystal and the caseback of the Deepsea, the amount of force exerted on the actual case itself remains relatively minimal. Additionally, as the crystal and caseback get squeezed together, with the majority of the force being supported by the internal compression ring, the front and back gaskets of the watch get pressed together, ensuring an extra tight seal.The caseback on the Rolex Deepsea consists of two components: an inner caseback made from Grade 5 titanium, and an outer, screw-down caseback ring that is constructed from Oystersteel (904L stainless steel). With a traditional, single-piece, caseback design, the entirety of the pressure placed on caseback gets exerted on the case of the watch itself, particularly near the threads. By separating the caseback into two components, Rolex is able to redistribute much of the force being exerted on the rear surface of the watch. The outer, screw-down ring performs the sole duty of keeping the inner, titanium caseback tight on the watch, while the nitrogen-alloyed steel compression ring ultimately supports all the pressure being exerted on the titanium case-back itself.
Today there is quite a high premium on original vintage pieces simply because they’re extremely rare and becoming increasingly harder to find. Decades ago, when people bought luxury watches like Rolex for example, it was perfectly normal for them to get the watch serviced, polished, or have parts replaced if you scratched or dented them up. The problem is that while they were done by the company with authentic later-era parts, they still weren’t original parts or features of the watch. Since this was such a common practice, today it’s really special – and highly valuable – if a vintage watch is totally original.When posed with the question of which watch to buy and when, every industry “expert” probably begins their answer with some variation of the same caveat: Buy for love, not for money. Watch collecting is a wild and unpredictable hobby. Auction prices for classic models have been known to hit eight figures (and then some), but most of the Rolex watches out there depreciate the moment you strap them on your wrist.I have a young friend who is ready to buy his first luxury watch. He’s been thinking about it for weeks (good boy), but every few days he calls me (bad boy) and labors the same point: He wants a watch that is an investment (even worse boy). There exists in modern watch collecting a problem: collectibility is now treated as a selling point. But the problem with everybody and their dogs knowing that something is collectible is that everybody and their dogs are quite likely to collect it.The most expensive wristwatch ever sold was the Rolex Daytona worn by Paul Newman himself. It fetched $17. million at a 2017 auction. That’s a pretty good price for a watch that was so unpopular when it was initially launched that it lingered on dealers’ shelves with relatively few actually making their way onto customers’ wrists. One of those wrists happened to be Paul Newman, who had reputedly been bought the watch by his wife, Joanne Woodward. And it isn’t that she made a sound investment, but rather her purchase created an investment piece by her gifting it to her stratospherically famous husband.
