This replaces my beloved old Caliber 2100, which I lost while on Jury Duty (thanks, security checkpoint, for making me take it off). This new watch has the same movement so I'm confident it will prove as reliable and accurate as the old one. My old watch needed only one service years ago for a minor adjustment to the hands; the power reserve dial remained doggedly in the upper range for nearly 20 years even though I seldom made special efforts to keep it charged. The "quasi-mechanical" chronograph works well. Substantial weight and size suits my wrist. I like the sapphire crystal although I would have preferred flat face rather than spherical. My only complaint (a minor one) is that the crown at 12:00 is a bit difficult to grip while wearing the watch.
Beautiful watch I swear my fiance almost cried!! Perfec twatch
