How to change the battery on Armitron Diamond Watch Model Y121E 3

if it is not the battery, your watch module has to be cleaned. that is the two reason why the watch moves like that. i hope i had been helped you.

mcdevito75 Here, Your Ann Klien watch may take a 364 or 371 battery, Best Bet is to look for a small watch repair shop in your area, the $15.00 cost is worth it as you would have to remove the back of the watch then un screw the hold for the battery, your time and effort really isn"t worth it, plus the new battery will last a year maybe even longer.

No need to send it anywhere; the band is generic and any decent jewelry store should be able to replace it.

Or you can go to the website and find out where to send it either directly, or you can download the manual.

You do noy need an exact Anne Klein band as all watch bands are made to specific measurements.
You have to measure the width of the band (the end attached to the watch) and buy any type of band you like, just make sure it is exactly the same width as the previous band. In case if you have the Anne Klein clasp or buckle, you have to measure the other end of the band as well and by any band you like, but in this case you need to match both ends of the band. Clasp or buckle are easily refitted to the new band and nobody knows that this is not an original one.
Do not forget to rate, please.

If your Armitron has a set of 6 inset notches around the back, as does my Y121E 20/1791F Armitron Diamond, that's a screw-back case that does _not_ pop off or pry off. You'll need a case opener tool, which is basically a small tool with adjustable-gap jaws that fit into two notches on opposite sides of the case and let you unscrew it. Wal-Mart sells this tool for about five bucks, and it'll pay for itself soon enough, as many watches have screw backs, and this will fit most anything you find. Head for their jewelry department and you should find the tool hanging up with the replacement watchbands and batteries.

The case is probably screwed down fairly tight against its O-ring seal, so make sure the tool is seated properly in the case notches, and turn it slowly and firmly counterclockwise to work it loose.

If your watch is like mine, it'll take a #377 cell, but wait until you've opened yours up to be sure.
