Hi, have seen this listing on ebay, the watch face and desciption say 21 jewels but I can only see 5 jewels on the movement? It’s a Welsh Smiths of course but there seem to be a few similar ones on google. Could I have thoughts?

thanks

Hello Sherlock and welcome..
The jewels one most obviously can see usually are those one can see like in these pictures. I would say one always should spot atleast 6 of them right away on the back side if they are there that is, some lower grade movements uses less jewels.
As you already know the jewels are both in the dial side and on the back, so you have to start multiplying every jewel you find  times two.
So in this case it is atleast 14 jewels (the balance has 4 with it's cap jewels too) which is the minimum for a movement like this to keep somewhat accurate time.
Unfortunately I'm not aquainted to these Smith movements but i'm sure someone in this forum is.

    • Plastic crystals have a lot of stress and this will eventually show up as a lot of hairline fractures on the crystal. If you are saying you want to save the original I would recommend not bothering they are considered consumables. Get an original crystal installed by a proffessional is the best route. Not much difference in price to buying one from them and installing  it yourself. Anilv

    • I have a few questions on the use of a (lever-type) jeweling tool in the adjustment of jewel endshakes, as I have never done this before. 1. If the endshake is too much or too little, how do you choose where to adjust the endshake? Do you adjust the endshake on the train bridge, or the main plate, or both? How do you decide which is the best? 2. When inserting the pusher into the spindle of a lever-type jeweling tool, such as a Favourite, is the best practice to take out the entire spindle from the tool frame to insert the pusher? And likewise, take out the entire spindle from the tool frame to remove the pusher? Or is it perfectly ok to insert or remove the pusher when the spindle is still inside the jeweling tool frame. Which way is safer/ best practice. 3. Is there an attachment to the base of the jeweling tool to hold the mainplate or bridges? I don’t seem to see any for sale, new or otherwise. Can I make one?
    • In the USA, you could try: https://www.jewelerssupplies.com/ or http://www.julesborel.com/ Cousins in the UK might be a possibility (although Waltham is a US watch, I'm sure some of them made it across the pond). https://www.cousinsuk.com/ Mark also has a list here: https://www.watchfix.com/category/watch-parts-tools-suppliers/watch-parts-tools-suppliers-us/
    • Yup. It's like the song from The Greatest Showman.... Never Enough! Never, never...
