Fossil blue am3922 doesn't work

Hi Cassandra.

this is what i found out from the net.

Most hybrids are compatible with any CR2430 coin cell battery, which allows them to hold a charge for 4 to 6 months. Swapping in a new coin cell lithium battery can be done easily and in just a few simple steps, plus CR2430 batteries are available from most retailers that sell batteries.

Watches Men Watches Women Watches FOSSIL

Fossil watches have an 11 year warranty. Any jeweler can replace the battery. If that doesn't solve the problem and you registered the watch or still have the receipt call 1-800-TICTOC1 for repair.

The vast majority of Fossil analog wristwatches take either a #377 or #379 watch battery. The #379, being slightly smaller, is somewhat more commonly found in women's watches than in men's watches, but I have seen both types used in men's and women's watches alike.
These batteries are commonly found at many drug stores, jewelry store counters at places like Walmart and Target, and even at some dollar stores. Be aware that cheap dollar store batteries are usually alkaline, not silver oxide, versions of the same size battery. Alkaline batteries may work perfectly well in many watches, but they have a somewhat different energy performance curve over time, and, in general, they won't last quite as long as a comparable silver oxide battery. In addition, for reasons I've never been able to figure out, some of the Fossil watches that I've serviced would not function with an alkaline battery--but would work fine when I put in a silver oxide battery of the same size and voltage. I have not been able to see a pattern to predict when this will and will not occur.
As a final thought, the backs of some Fossil watches are very snugly fitted to their cases. You can generally get them off without too much of a problem, but there's a good chance you may need a jeweler's press to get them to snap back on properly. I've noticed this most with round watch backs; I generally haven't needed a press to close oblong or tonneau-shaped Fossil watches (or some round watches, too). A jeweler's press spreads the pressure evenly around the edges of the watch back and watch case, preventing damaging pressure on the watch crystal, watch movement, and watch back. Clamping the watch in a regular vise to try to press on the back runs a high risk of damaging your watch, and I do not recommend trying that, no matter how frustrated you get. It's much safer (and cheaper, overall) to tip someone with a vise a couple of dollars to close up your watch for you.

Hello:
The battery number will be imprinted on the dead battery (for that watch it's most likely 379), however, I wouldn't recommend replacing a battery on a Fossil yourself. They are notorious for their back being incredibly difficult to remove and put back on and if you're not a professional, you will most likely break the crystal in the process. If it's a screw-back (and you can tell because it will have six rectangular shaped notches around the edge of the back) you won't be able to get it off unless you have a case wrench and a case vise. Take it to a jeweler and have them change it for you. Screw-back Style Case

fossil watches are very temperamental when it comes to there insides. did you have fossil do the band or someone else? also they sometimes have corrosion from the seals not lasting.

to change the battery of fossil blue watch,just open the case back and remove the old battery,look the number size on the battery and put a new battery that same number size ,after replacing battery press the case back tight to avoid water damage !good luck

take it to a jewlrey store, like sergios. They know how to fix all watches. I took my fossil blue to 4 watch stores including the fossil store in the mall and none of the stores could fix it. I took it to sergios they changed 2 batterys in like 5 minutes with no charge.
