My old 2000 Professional today. I'm thinking about sending it to Tag Heuer for a full overhaul. Bought it new in 1991 and I've never even had the back off it.
Never seen another one of these (on Internet, yes, but never "in the flesh".) The 18k gold crown and pushers and bezel markers distinguish it from the others.
Small by modern standards, but still a favourite.
Afternoon switch to 6309-7049 for the gym...sporting Metallica's "Ride The Lightning" t-shirt...unfortunately, the gym management refuses to play Metallica on the PA system...no big deal...so I walk around [the gym] singing Metallica out loud...which is AWESOME. 馃憤
