I have used them twice.
Once to service my Navitimer at two year mark, free of charge.
Once more to service my Chronomat 44 that was not maintaining wind/power reserve.
Both times were handled professionally and rather quickly. Had them back in under a month, closer to three weeks.
I went online, filled out form, waited for shipping box in the mail and sent it to them.
Will use them again.
