Reviewed by the Fine Watch Guide team · October 2026
The Submariner set the template for the modern dive watch in the 1950s and remains the reference point for the category, with a rotating bezel, luminous dial and an Oyster case built for depth.
Most Submariners spend their lives nowhere near the sea, but the watch is still engineered as a dive tool, and that shapes how it should be looked after. Gaskets, crystal seals and the screw-down crown do the real work, so a Submariner service is as much about water resistance as it is about the movement.
A full service takes the movement apart, cleans and lubricates it, replaces worn parts and regulates it, then reassembles the case with new gaskets. The step owners undervalue is the last one: pressure testing the finished watch. A Submariner that keeps perfect time but leaks at the crown tube is a ruined movement waiting to happen, so a specialist should test water resistance after every service and ideally once a year for anyone who actually swims in it.
Bezels deserve attention too. The rotating bezel on later models uses a ceramic insert that resists fading and scratches, while older aluminum inserts fade and pick up marks that many collectors want left alone. A watchmaker should clean the bezel mechanism so it clicks crisply without replacing an original insert you'd rather keep.
Any competent Rolex watchmaker can service a modern ceramic-bezel Submariner. Vintage references are a different job. Their value depends heavily on the original dial, hands and bezel insert, on tritium lume that has aged evenly, and on cases that haven't been polished into soft shapes. A specialist in vintage Rolex will service the movement and renew the seals while treating the cosmetic parts as untouchable unless you say otherwise.
That distinction should drive where you take the watch. If your Submariner is a recent model you wear daily, prioritize convenience, genuine parts and a proper water test. If it's decades old, prioritize a watchmaker who can show you vintage Submariners they've serviced and returned unpolished.
The Submariner is one of the most counterfeited and most modified watches in the world, which is a reason for care rather than fear. Before you buy, have the caseback opened and the movement checked, confirm the dial and bezel are correct for the reference, and look for signs of aftermarket parts such as non-original bezels, refinished dials or added diamonds.
Condition counts as much as authenticity. Bracelet stretch, a tired bezel action and an unknown service history are all negotiating points, because the buyer inherits the next service. A written inspection from an independent specialist gives you facts to bargain with or a clear reason to walk away.
Rolex has made the Submariner with and without a date window since the late 1960s, and the two versions use different movements as well as different dials. The no-date has the cleaner, more symmetrical dial that many collectors prefer; the date adds the Cyclops magnifier over the window and a quickset date function. For servicing, the difference is mostly about the date mechanism, which adds a few parts to inspect and lubricate.
The 2020 update moved both versions to a 41mm case and to Rolex's newer generation of calibers, with a longer power reserve than the movements they replaced. If you're choosing between generations, the practical differences are case shape, lug width and bracelet feel, so try both on before you decide. A watchmaker can tell you which movement is inside any given watch in a few seconds, which is worth doing on any pre-owned purchase.
Older Submariners came on folded-link Oyster bracelets that stretch with years of wear, and a badly stretched bracelet sags around the wrist and can let the watch slip. Modern bracelets use solid links and a Glidelock clasp that adjusts length without tools, a real help for anyone who wears the watch over a wetsuit or in summer heat. Both kinds need the pins and screws checked during a service, because a worn pin is the usual reason a watch ends up on the floor.
The screw-down Triplock crown is the other part that takes daily abuse. Wind and set the watch with the crown fully unscrewed, then screw it back down gently until it stops; forcing it or cross-threading it damages the crown tube, which is a bigger repair than the crown itself. If the crown starts to feel gritty or won't seat cleanly, stop wearing the watch in water and have it checked.
Once a year if you swim with it, and after any service or crystal work. Gaskets age with time, not just use, so even a desk-diver benefits from a periodic check.
Only after a watchmaker has renewed the seals and tested it, and many owners of valuable vintage pieces choose not to risk it at all. Treat its original rating as history, not a promise.
On a vintage watch, usually not. An evenly faded original insert is often worth more than a new one. Keep it, and if you must swap it, keep the original with the watch.
The movement and its caliber, correctness of the dial, hands and bezel for the reference, bracelet stretch, signs of polishing, and water resistance. A specialist can cover all of it in one visit.
