    Hello:
    I am watching a couple of auctions on Seth Thomas Regulators. They both "look" like World models. I know the 40 movement is a 15 day double spring with graham deadbeat, but what is the 86W? Is it also a 15 day, or is it a 30? The movement looks the same as the 40...... Any ideas?
    Thank you!

    Yep...the 86W is a 30 day movement if original....
    The 40 is an 8 day...both go into a World or an Umbria...
    40 tooth escape wheel in each....80 beat..

    My World 40 is a 15 day that will go about 21 days if I let it.
    What is the main difference between the World and the Umbria?

    Grant,
    I have the Seth 15 day mvt in my Umbria, World, 14" Lobby....the 30 day in my 24" Marble Gallery.....also have an 86W in a sort of Umbria case...it has extra gears on the outside of the plates that obviously ran something else...but not sure what as it is no longer there....It does not hurt the running of it as it runs for the 30 days with the correct pendulum.
    The difference is the cases....Both World and Umbria have the same three options of movements...all are 80 beat...but they are in different cases...
    You can see some of mine below....

    Hi JJ:
    It is not mine, it is an e-Bay listing, but I think I am prohibited from linking to the board when it is active. Correct? The item # is
    130096148264 and it does have the winding stops. Do these typically command a much higher price compared to the 40?
    Thanks again,
    gp

    Hey Grant,
    I was confused...I thought you posted that your World ran for 21 days if you let it.........I was wondering if your clock had the winding stops...or was the 21 days an answer to a question you had for the ebay seller?

    As far as great value...maybe a little more...certainly not a major difference....other than on ebay you can never tell...if someone wants the 30 day, it could get wacky.....

    Hi JJ:
    Sorry.. Yes, mine will run for 20-21 days. It is a 40 movement and it does have the stops. btw, now that we are on the subject, do you know if replacement pallets are available for these deadbeat movements? I know I saw some for the ST#2. Mine has some fairly good grooves and before I re-surface I thought I would look around for new replacements.
    Thanks again.

    Grant,
    I just mailed off my extra #40 mvt so cannot tell without taking a dial off, but I am almost postive that the escape wheels for the #40 mvt and the #2 mvts are identical....I will check today because I am wanting to take some pictures of my weird 86W mvt and will check it against my spare #2 mvts....

    Grant, I just posted the thread on my odd 86W clock.
    As to your other question. After examining both, I am sure that the escape wheel and verge are identical on the Seth 77, 77A, 77B, 40, and 86W movements.
    If you are able to make an after market verge work on a Seth #2, you should be able to make it work on your World.
