Well, I finally got the 1000T after five anxious days due to US customs. After the 1000s of Doxas imported you'd think they'd have their act together. It was worth the wait. Now for my impressions. It wears like the 600T, maybe a tad more comfortable, if that's possible. My wife asked why I kept looking at it and I said because I can't tell it's there. Regarding the color, The 600T is a tad darker, a casual observer would be hard pressed to tell the difference. The height difference is undetectable when being worn the largest difference being the caseback. It's like you took any shortcomings of the 600T and fixed them. The 1000T has got more lume on the hr. markers and minute hand. A better Crown. As to the bezel it's a tossup, I like them both and actually favor the 600T as it's got a firmer action. Finally solid end links and screw pins at last. The crystal is perfect. I compared it to a 36 year old Waltham with an acrylic crystal and when you look at them from the side it's hard to tell the difference. Doxa IMHO you've got another winner. You did what you intended.
I love it, but then I'm biased and can honestly say, I've never met a Doxa I didn't like.
