If I plan to buy a brand new mechanical watch (chronograph) of Longines, the retail price around USD1,900 and it equipped with the movement ETA Valjoux 7750, so what should I expect the accuracy per 24 hours? Thanks all!

As far as I know the 7750 is a chronometer, therefore you should expect it to run within COSC specifications (-4/+6 seconds a day). Otherwise a modern regular mechanical watch should usually run within -5/+15 seconds a day, more or less.

Thanks Carl, but I think it's quite positive.
