These are my thoughts and observations based on the Doxa site photos and specs. I know the same as you guys do.
I like it. But then I've never met a Doxa I didn't like. It is the same size as the vintage 300T which I prefer over the 750T. However I prefer to wear the 750T compared to the 600T because I don't like the domed crystal, but that is my preference. I personally would have made it with a flat crystal just to distinguish it from the 600T. But I know many people are big fans of the domed crystal.
I don't know if it is a thicker case or a thicker caseback which gives the increase in thickness. I hope it is the case. I like the extra graduations on the dial. looks sharp. I like the way the lume and index markers have lines between the black and the lume, expecially on the Sharkhunter. Looks like the lume on the minute hand is larger too.
My assumption is that the watch will look similar to the 600T but have the thicker 120 click bezel from the 750T and it looks to have the superior crown from the 750T. Also it has the newer bracelet. All in all I think Doxa took the best bits from both the 600T and the 750T and made a better overall watch in the 1000T.
I'm also disappointed they never released a HRV Conquistador for the 40th Anniversary. Big, big occasion lost, in my mind. Even if it comes out in say September, the impact among Doxa's peers will not be the same.
Hell, it it had been me, I would have made up a dial. Drilled a hole in the side of the SUB 1000T and stuck in a rivit to look like a HRV, called it a prototype, stuck it in a glass case beside my Conquistador and said not available until summer 2007 and basked in the glory. But then that's just me. Hell I would have put Dr. Pete Millar on the dial and called it a 40th Anniversary book celebration prototype
Looking forward to seeing real photos and comparisons. i'll bet it is even better in real life.
