I have a fairly old jack daniels pocket watch and i cant seem to find any info on it...value.. manufacturer etc ..I do have a serial number 3780 G

Take it to a jeweller, aan antiquary or maybe a good pawn shop

Check to see if your watch or one closely resembling it, is for sale on Ebay. This generally gives an idea of value, at least in terms of resale and value. Watches, other than Rolex and very high end types, don't have very good resale value. Of course, all of the value may be in the diamonds or 14K cases, no matter who is the maker.

NEED MORE INFO. From that serial number, it might be one of the old tuning fork movement watches. If the date code is from M0 (1960) through N6 (1977) it likely is. If so, it has a collector's value. In any case, the exact model, type of movement, and year would be needed to come up with a value. The serial number is just not enough.

It's rarely possible to give any kind of definitive valuation without seeing a watch (pocket or wrist) in person, but it sounds like you have an inexpensive pocket watch that was probably made in the 1960s, less likely made in the 1970s or 1950s. The use of the term "antimagnetic" on the watch, as opposed to "17 jewels," suggests that the watch is powered by a 1-3 jewel pin lever movement, rather than a more expensive movement. These movements can keep quite good time, but they are not valued by watch collectors unless the rest of the watch is of compelling interest.

In terms of value, your pocket watch has more value as a piece of jewelry than as a vintage timepiece. Most watch collectors would not be particularly interested in your watch. In the United States, I've seen similar watches, in running condition, sell for $5-10 at vintage watch fairs. Around where I live (the Northeast), as a piece of jewelry, your watch may be worth twice that but not more. I cannot speak to pricing in other parts of the country or internationally.

Your watch is a 1896 model, manufactured near the end of the production runs for that year. Check this link to verify Waltham Pocket Watch age, and manufacturing info:

Get a copy of the "Complete Price Guide to Watches by Cooksey Shugart", and check out pricing for thousands of watches. I've found that many of the common Walthams and Elgins for that series will be valued between 75-250.00 for standard production runs. If the watch is rare and has a 14 k or 18K gold case, then the sky is the limit, depending upon condition and the actual weight of gold in the case, and/or movement.

As you can see by the serial number these watches has been manufactured in vast numbers. I can't give exact date when the watch was manufactured, but it was definitely in 1960-1970-ies. Some watch manufacturers still do produce editions of M. Mouse themed watches, but now they are not in trend, so, not too many people buys them. Worthiness of your watch can be given if the experienced watchmaker/watch dealer see it in the flesh, as there are too many things to be considered: type of movement, overall looks, time keeping, even the type of picture of M. Mouse. All I can say is: do not expect a fortune. The best way for you is to make evaluation of the watch and then put it on specific watch/clock auction. Rate me,plz.

RECOMENDATION:
Find a registered repair person in your area. It is very difficult if not impossible to find a value on you watch via the Internet sight unseen.

The serial number is usually engraved on the movement. If you open the back of the watch, you should be able to see it.

I looked at the Hamilton pocket watch site (in might be helpful if you visit the site, simply type "hamiltonpocketwatches.com" into your search engine and your will be able to examine photos of a number of movements).

The position and size of the number varies but it shouldn't take to long to find. One of the pictures I found impossible to see the number but the rest I found, although sometimes you had to look quite carefully.
