It is in excellent working condition. The only thing missing is the seconds hand. It is 18k gold except for the chain which is 14k. I don't know the answers to your other questions... Can you help me by looking at the photos uploaded here? Thank you very much!

How long is a piece of string...

The best bet is to look at eBay "sold" prices for 100-year old 18k gold pocket watches. Unless the movement and dial are exceptional, all the value is going to be in the scrap value of the gold. Is it key wound or crown wound? Is it a hunter, half-hunter or open face? Is it worn, scratched, dinged, perfect? Engraved, machine-turned, unmarked? What's the case weight without the movement.

Also check out online auction catalogues - try:

to see what the estimates are - but remember they're just a rough guide and may sell for a lot more.

If you can post a link to some pictures here, we may be able to help more.

Hi everyone!
A friend of mine has a CHAMBERS LONDON 18k gold pocket watch. It was given as a gift to his grandfather and has stayed in the family ever since. It has some marks on the back cover: JM, 18, crowns. Do you know if it's of any value and where can I ask about it? I can't find any info on the Internet. Any help would be appreciated. Thank you.
