To sway off topic just slightly. Did I read that a Chronosport is a Breitling or related to it somehow? I have a Breitling that is about 6 years old and it has a few similarities to a Chronosport. I love Breitling and it is also indestructable.....touch wood.....and it's also used by the RAF. Also being a bit of a flight junky myself...
I think the UDT used the same movement as the Breitling Pluton (and both movements are next to impossible to replace) but I don't think the two companies are related. I will say though that when I had the Sea Quartz 30 about 5 years ago (got the idea to get one from Ghost Writer close up shot!), I had it serviced by Chronoserv. They had to put a new movement in it and fit a new crown. well the crown sported a large cursive "B" just like on alot of Breitling models! I was pretty shocked and think there might be more of a connection, though they could have just used the same parts supplier since neither make all parts of their watches.
On the Rolex, there is also a company now named Debaufre that sells a 42mm GMT style watch. A bit larger than the one TM wore but has the sapphire crystal, ETA movement and is WR to 300m I think. A good deal if you don't mind that the name is different, and if you're like me and never rememeber to take a watch off before swimming.
Oh, and if you ever thought of getting a Rolex, now would be the time. Rolex changed the case design about a year ago and no longer make the Pepsi bezel (except in diamond encrusted hideousness), plus they raised the price on the newer ones to over 6.5K If I had the means I'd get one but that won't happen for several more years yet, if I ever do.
Oh, and on a Chronosport look alike? There are several options. The CWC company supplies dive watches (and regular field and chronos) to the British military. They make a C-sport twin! Uses fixed bars so you have to use a NATO style strap but that just makes it more secure and you know your getting a military certified watch so use and abuse aren't an issue.
also check out Timefactors.com under their watches. Tehy make one with a date only display, 10 yr battery and a sapphire crystal. Very nice watch and uses regular spring bars.
