After having a horrific experience at Tourneau to change the battery for my Ebel watch, I was thrilled a few years ago to find Manhattan Time Service. I have used them twice now to change the battery, repair & check my watch. Their rates are really reasonable & they do not keep your watch forever. Touneau kept my watch 3 weeks to change the battery; Manhattan Time Service kept my watch 24 hours! They are truly professional & honest – & polite & friendly as well. It’s a pleasure to deal with them & I just hope they will be in business for many, many years to come.
