and I fully hope to own it one day soon. I prefer it on the bracelet, as I love JLC's adjustable clasp to tighten or loosen the band "on the fly." However, the points made regarding travel watches are valid. The Geographic and it's variations (save version 6, which I'll get to in a moment), were designed for someone in an office who is tracking other timezones, since the date is activated by the main time, and the world-timer is not date-linked at all. The Dualmatic or GMT do allow you to travel forwards or backwards across date lines, keeping the "home time" or reference time set on the hollow hand.
The Geographic version 6 is the Diving GMT (version 1: the original, released in 1989; version 2: the 1996 update - "Watch of the Year;" version 3: the 2004 Compressor Geo; version 4: the 2005/6 "Harmonized" 40mm version; version 5: the Geographic World; version 6: the Diving GMT.
The Diving GMT has the movable city disc, but also allows you to advance or retard the hour hand on the main time, advancing or retarding the date. If you're patient, I imagine that version 7 will be right around the corner - if not this coming SIHH, maybe in 2012 (if the world is still here).
