Can't go wrong with a Tungsten, they keep looking like new.
The cases that is, my M24 suffered moisture damage and is in need of a rebuild.
Mine got some moisture in it too at one stage. I cant remember if it was the M26 or the M27, but I was working in North Queensland as the time. I posted it back to LumTec and they dried, cleaned, lubed and retimed it free of charge other than my postage there. They are a top company, not sure if that will continue as they grow though.
I really do love my LumTec's but the M27 I want to sell is too busy on the dial as Ive drifted to more simpler looks these days. That and the fact is doesnt get a run anymore. I only wear my M26 with rubber in summer, leather in winter and my Casio GShock to work (dont hate me, I already despise wearing a battery operated POS as it is, but it vibrates on the hour in the noisy power plant and also doesnt stop ticking near the generator lol).
I have a V1R I also toyed with selling, but I simply cant part with that one... The case depth and movement detail are simply too good!!
