It now won't flash!!!

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.

Did you change the battery 3 months ago? Wrong type perhaps?

Was the watch bought new with the battery? Watch in storage and display for 9 months, you had 3 months, time for battery change.

yes it is battery operated,sudjest you get the battery changed at local jewelers.

your watch has two batteries inside, the small battery is the one that had to be replaced. it is under the big battery, the small battery makes the minute and hour hand move while the big battery makes the seconds flashing. i hope that i had been helped you.

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. However, the Fossil CH2473 includes chronograph functions, which means that you can have multiple motors inside the watch running simultaneously. As a result, it's possible that this watch will require a different / bigger bigger. However, if it's not one of these batteries, or even if it takes a 3-volt lithium battery instead of a 1.5 volt watch battery, it will still be something pretty mundane.

In general, common batteries like the type I expect you'll find inside your watch 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. Lithium batteries, whether "brand name" or generic, should have the same performance curve.

If you do open up your watch to change the battery and don't recognize the battery type/code on your battery, don't give up. Watch batteries have different numbering schemes, depending on the manufacturer. Here's a link to a cross-reference chart that will help you "translate" one code into another. I would suggest starting by looking at the #377 line to see if one of those cross-reference codes matches what you have. However, you may need to look around the chart to get an exact match:

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

1)Get the battery out again and check for power. 1,5 Volt batteries should be 1,52V - 1,54V and the 3Volt batteries shold be 3,1V - 3,3V in charge.
2)Take the hardened steel needle or watchmakers screwdriver and clean (scrape) both contacts off any visible residue till they are shiny. aaaaaaaUce dust blower to get rid of scrape-offs.
3)Make sure the contacts are touching the corresponding battery side only and not shortcuting the battery.

Do not forget to rate please.

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

I suggest you consult your authorized Fossil Dealers for the correct battery replacement of your watch.

Thank you.
