I just saw the Sablier at Cooper Jeweler in Warren... wow!!
The jeweler sent me to this site:
The Sablier Grand Cru Collection ~ It’s About Time (and Wine) | Grape Experiences
I asked about the movement and it is ETA 2824-2... I guess the price went up because they were asking $2100 for it which I'm going to buy. First watch with a concave crystal, dial and hands in the history of watch making!! Sales guy said they have the patent thru 2029. Also the jeweler had a copy of the actual patent... so cool
Hope this helps... let me know if you hear anything else about it
