The other day I was flipping through some auction sites and stumbled across an offer to buy a Moeris pocket watch movement for about €19 (22$). Took a look at it and thought it would be a shame not to bid on it.

The UNITAS 6498 is a quite nice movement and been cloned by many Chinese companies. Later on it became named ETA 6498.

Most people start their practice career working on a ETA 6497 clone which is a cousin to this movement, they are slightly different in the layout.
So here is a PDF as a small introduction to the UNITAS / ETA 6498 which shows my standard service approach to a movement like this and a small tutorial in how it ends up in a Chinese watch case. 
The PDF is optimized for use online to save server space.

And here are some example shots from my service notes.

Here another PDF that shows the part break down and also where to oil and which to use.

Thank you, but I already have the ETA tech sheets.
My Tutorial only shows an alternative and a more detaild way to service this movement with some tips and tricks.
One more tip I can share i were to find all the latest tech sheets.
This is for the ETA/UNITAS 6498.

      Setting power reserve on LeCoultre Futurematic

      By watchfellow · Posted

      Thanks everyone for the replies. It seems setting the hand is a bit of a guessing game, and I thought there would be a very specific way to do it. Since the reserve indicator hand moves clockwise as the spring is wound, I tried setting it right at the start of the black side. But setting it there doesn't really make sense, because by the time the spring is halfway wound, the hand is only at the end of the red side... In my head halfway wound shouldn't mean the hand is still "in the red."

      Lovely part of the country! I spend most of my days driving along the A64 for work in and around York. I'll be sure to drop plenty of questions soon! I've actually got a couple of watches on the way that I'm pretty sure I'll need some help with! They look pretty beat up from the pics but I love a challenge and an excuse to buy more tools 🤣

      Help - London Elliott Mantle Clock Night Silence

      By oldhippy · Posted

      I have two of these in my home. You need to remove the movement from the case, take off the hands and remove the dial and take a few good photos of the front plate so I can see what the problem is. The round nut unscrews and the hands pull off pull them off from the center and not the tips as you could break them.

      Help - London Elliott Mantle Clock Night Silence

      By MapleWood · Posted

      Hi everyone, I tried looking for answers on this online but came up with nothing, so I'm hoping some of you knowledgeable people might be able to help. I have an Elliot clock that has been in my family for at least 4 generations. I recently enherited it, and I'm trying to get it to run properly again, as it's been neglected a bit.  Here,s the problem. These clocks have a silencer mechanism, which is supposed to stop it from chiming between 11PM and 7AM but for some reason mine is silent between 1AM and 9AM. I have tried figuring out how to adjust it but have not managed. Does anyone have any idea on how to correct this? Please find attached some pictures of the clock. Thank you!
