People who are into tobacco-related "stuff" may have some interest in Camel watches. People who are into watches mostly won't; however, there may be some interest in them among folks who collect watches made/offered by makers of non-fashion or non-fashion accessory goods. A Mickey Mouse watch is one such watch, although many Mickey watches had more horological "chops" than does the Camel you've pictured. Given the negative attitudes toward cigarettes and smoking, it's probably safe to say that your Camel watch may become a collectible piece some day, but it won't be among traditional watch collectors that it does so, and it certainly won't become collectible on it's merit as a timekeeping device.
As a timekeeper, it likely keeps time better than even the most pricey mechanical watches. That's not uncommon for any quartz movement to be able to do. The structural integrity of the case and strap is a different matter. Seeing as no depth rating is given on the dial, I wouldn't suggest doing more than showering with it on, and even that is best limited to cold showers as the heat from a hot one may weaken the glue that hold the crystal affixed to the case.
I suggest you just put the Camel in a drawer and ever decade or so check with an appraiser (auction house) to see if there's some interest in it. An auctioneer will be your best bet for finding the rarefied folks who'll value that watch enough to make it worth your while to sell it if you want to. This forum is almost certainly not a good venue for trying to get top dollar for it.
All the best.
