sorry, but Timex (no 24hr hand move the bezel to the 24 hr had) is just copying the GMT Master Rolex. Look at the Bezel. I've been wearing the GMT Master Rolex for 35 years.
Here's a bit of trivia: What watch was did special forces use in the field in Vietnam?
Ans. GMT Master (pilots watch), why because it's the most reliable watch made in the world.
Timex meh!
My brother was in the special forces and he told me if you ever buy a watch buy a rolex, and I did, and still keeps perfect time.
