Vintage 1940. Doesn't run. Numbers on back of case illegible. Dirty, but intact. What have I got?

There are very few makers that give access to serial numbers Victoria. They are just a numerical sequence. I can do more with model numbers as far as searching goes. What you can do is contact Dolce Gabbana Customer Service direct. They actually like enquiries like that.

Based on your description, it sounds like you might have a vintage Rotary watch. If you are able to provide the specific model number of the watch, you can use the Rotary watch database to look up the production year and other details about the watch. Additionally, if you would like to learn more about vintage watch care and maintenance, there are plenty of resources online about how to best care for your vintage watch.

different watches have different case backs. You need to send a picture with yours or send the model number so we can see what is the case back system. Omega has many vintage ladies models.

Serial numbers are always in the back of the case or on the movement. Take to a local jeweler.

I got this Lucien Piccard gold watch in a vintage shop with no model/serial number anywhere. Can someone identify if it's real LP or a replica?

put make model and any numbers into google.
or put more info on here.
or if you are asking were is the number on the watch you will have to take the back off it and see if there is a number in there.

You should ask an antiquary or a good pawn shop. Or do a search in abay sometimes they have similar vintage stuff

It looks like a gold filled case and of course it's a standard wind. I would put a value on your watch if it is in running order of $100.00. This may not be what you could get for it but if it was being sold in good running condition that would be a fair price. Hope this helps, gabe.

Bulova began using a series of codes in the late 40's to date watches, look on your case for a letter followed by a number,the letter designates the decade,A=40's,L=50's,M=60's,.N=70's,P=80's,T=90's and the following number designates the year, an example would be,M4 would indicate 1964. Hope this helps,the serial numbers are used for identification purposes only

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.
