GunCollector, great article on Rolex at TimeZone! I have been wearing the same Submariner for 21 years in all types of environments including radiation areas. NEVER HAS FAILED ME. I don't care if they have mud in the movement as long as it performs and I can bet my life on the watch. My wife has a Two Tone ladies Rolex, failed once in 21 years. Daughter has Tudor for 15 years, no problems, recently purchased Rolex. I have had a SS Daytona for 7 years, a tank. Yes, Rolex is on the low end of expensine mechanical watches and the internal finish is certainly not up to high end watch standards, but Rolex's keep on ticking in environments and use that would destroy most watches. Any out there had their watch go 21 years in all types of service(hunting, white water and flat water canoeing and kayaking), look like hell and still functioning? -Dick
