I just recieved a Fossil FS4249 chrono wrist watch. It has a tachometer with serated/knurled outside ring. The ring does not appear to turn. No mention of the use in the instruction booklet. Thanks, Jeff

try useing Google you will be amazed at what you can find. give it a try !!!!

Thanks for contacting Fossil.
The only way to know the battery size is to pull out the old one. It might also be in your manual. It might be on the outside of the watch.
If battery is missing, then you will have to measure the cavity and match it against a battery chart.
Best wishes.

Go to a watchmaker/technician. They will have a press that they can use to apply even pressure putting the crystal back in place. Be careful that you do not lose the teflon seal sitting where the crystal goes and do not let any dirt or contaminants get to the face of the watch. Be sure you ask them to pressure test it to be sure it is water resistant.

Type in your browser FOSSIL WATCHES.
You will find numerous sites. Go thru them till you find what you're looking for.

Your description of the problem is not clear but if it is not running properly and is within the warranty period, then take it back.

If it is outside its warranty period then a watch repairer will sort it out for you.

go to fossil.com click on customer support that is where the manuals are hope this helps

On this type of watch the second should not be working unless you are in the chrono mode. The lower dial should be the only indication of the seconds when not in chrono mode. You probably need to have the chrono reset and shown how the functions work. Try a Fossil location they will be able to tell you how to work this watch. It does not sound like this is a major problem.
