I never understood what the big deal was with Movado battery replacements. My wife & have a couple of 30+ year old Movados, & when the first one needed a battery replacement, I tried a few watch places & they all said they'd have to send it out. I opened it with a case knife, found the right battery, & I was done.
On another note, my Movado is what they called their "Museum Sports Edition", & had small gold dots in the band links. One of the dots disappeared, & it was like pulling teeth to get them to send me a replacement dot. Cost about $20 plus shipping, IIRC, 20 years ago. They REALLY wanted me to send it in to them.
