About six months ago I purchased an Acetimer1000 off their fleabay site. It's simple to use and has all the functions I need to adjust the watches I work on at home.
Anyone who's been watching my watch service walkthroughs know I recently serviced a Miyota 8200 Automatic Movement, which timed up very nicely on the Acetimer1000 ... with a Beat Error of 0.0 in Dial-up position. Well, the next day I put the same watch on a VERY expensive timegrapher which is certified and calibrated. In Dial-up it showed a Beat Error of 1.3!! THIS IS NOT GOOD GENTLEMEN!
I understand you get what you pay for; but we are not talking features here, this is simply calibration at the factory.
Now I'm not going to bag the Acetimer1000, yet, and I always give a company an opportunity to fix problems. People aren't perfect, and mistakes can happen ... the person who calibrated my unit might have had an off day.
I have emailed Acetimer.com and explained my situation, and I will keep everyone updated on the outcome.
