The new watches like my sub are 28 800 revs so they need special oil and need more maintenance more often
Totally depends on the movement
There's a lot of misinformation on this thread. To address the above, watches beating at 8 Hz which is 28,800 cycles/hour have been around for 30-40 years and the modern lubricants last a very long time. Also, most pass produced modern mechanical watches beat at this rate. Also, most of these watches have recommended maintenance intervals for 3-5 years but most people don't service theirs until they notice a problem like poor timekeeping.
For the gentleman whose Rolex seized, this is very rare and likely due to going 14 years without a service. Rolex movements are amongst the most reliable and accurate movements on the market, They are designed with tough components and loose tolerances to last for a long time. The escapement (the regulating part of the watch) is state of the art and uses only the best components and design.
By the way I've never owned a Rolex and probably won't as they are not my style but I do have great respect for what they do and in particular their bulletproof movements. Ask 100 watchmakers their thoughts and 90 will tell you the same.
