I could not find any information on your watch but if it is an automatic type (self winding), it could be that you do not move around enough to wind it up.
To fully wind it, hold it in you hand and wave it gently from side to side for about 100-200 times. This will give the spring a good store of energy. These watches usually can store enough energy to run for 2 - 3 days if nort in use.
When you say "wave wind" do you mean you're waving it around to wind it with the self-winding mechanism? If so, that will only keep it running briefly as you're experiencing. Manually wind the crown about 40 turns clockwise to "fill the tank" and wearing it daily will keep it topped off. Anytime you don't wear it for a day, manually wind it again.
As for the cleaning, the inside of the watch doesn't get real dirty but over time the lubricants wear out and thicken which makes the watch run slowly or not as long as it has to work harder to move the gears through the thickened lubricant. A watchmaker can disassemble and clean the old lube out with solvents and then reassemble the watch with fresh lubricants.
Automatic, or "self-winding" watches get their power from movement of your wrist throughout the day. Unless you're quite active the amount of movement is just about enough to keep it running till the next day. However, if you let the watch run down completely as you did when you were away, there is no reserve power left. The solution is simple: just manually wind the watch and you'll be good to go. To manually wind the watch unscrew the crown as if you were going to set the watch but do not pull it out as would for setting. Wind the watch about 40-50 turns and it will run fine if you wear it every day.
Is it an automatic self wind or wind up? An automatic watch has a weight that winds the main spring and if you wind it by the crown it will not stop. If its one that you wind by hand then the watch should be wound daily at the same time...like right before bed or when she wakes up. Wind gently until it stops. That costly repair should come with a warranty so if she consistently winds daily and still loses time you need to send it back!
If the watch is an automatic then she can gently hold the watch in her hand and rock it back and forth a good 20 times or so and that will give it a good winding! This is a common issue we see at our watch repair business. Some people do not move enough during the day to keep an automatic movement wound. If thats the case then there is nothing ong with the repair, just make sure it gets a good daily wind! :-)
Self winding watched should not need to be wound as long as they are being worn.
To tell if the self winding mechanism is working, hold the watch close to your ear (hold it vertical, as though it was on your wrist) and rock it gently. You should be able to hear a ratchet operating (a soft clicking noise).
I can't help thinking your suspicion about the mechanism having failed, sound very likely.
I have found that some of these "automatic" Fossils also contain a battery. That is how that provide an automatic watch at such a cheap price. I recommend taking it to a jeweler to have them check this. If it needs repair it will likely cost near the watche's replacement value.
I also have a Prague automatic watch (not the same model) which I purchased in 10/06 and have had it repaired twice. If you purchased the watch new, a little white warranty paper should have accompanied it. If not, you might be out of luck. Anyhow, each Prague has a two year warranty. My warranty instructed me to send the original receipt, a check for $10 (for return shipping) and the watch to Croton Repair; 195 Anderson Avenue; Moonachie, NJ 07074. There of course is no phone number to call them. Make the check out to Croton Repair. The warranty also says they do not guarantee they will fix the watch, but they guarantee they'll send you the watch back if it cannot be repaired. It took about 5 weeks and my watch came back repaired. Unfortunately about 6 months later it broke again, same exact problem (no long self-winds, ticks or keeps time, my watch also has a diamond at each hour, two of which fell out)... I've seen a lot of the issues people are posting seem to be the automatic watches not working. Probably duds, the inner workings seem to be very sensitive.
