re: GMT Master user guide by spaceghost on Jun 03,2004 09:45 PM Hey congratulations! I have a GMT 16750 from 1981, purchased new. Runs and looks as good as day 1!! If you wish send it in for Rolex service at an authorized Rolex service center..expensive but worth it, your watch will look new !

The following site is for GMTll so they highlight the quick set hour hand and independant 24h hand.Our GMT's don't have these 2 features but I'm sure you'll figure out what to do. http://www.koniaris.com/rolex/gmtmaster2.html
