Many time I have run into this on older movements and that is  surface rust on the train of wheels teeth's even after pulling them from my watch cleaning machine. I end up cleaning them under my  microscope using a old oiler and whatever else. This takes time depending on how bad it is and was wondering what other do since we know this has to be cleaned.

I should has said not on the brass wheels since brass don't rust but on metal teeth's them self.

Rust residue from the pinion and leaves could spread onto the train wheels.

Perhaps a picture to show us what you mean wudce.

Here what I'm talking about. It's  surface rust not the kind that's eaten into the metal, I know if it had I need to replace it. This a center wheel from a movement I'm working on and it had this on there before I put it into my cleaning machine. This can be clean off but takes some time to do so.

      I only buy mechanical personally, as it's all that interests me. There are a few electronic movements I find interesting, but they're not the sort I tend to see very often at all, and wouldn't come up in any of my searches. I have been given a few quartz watches over the years, but they all just sit in a bag in a drawer. Once I hit some critical mass, I'll hopefully get enough motivation to either sell or donate them.

      Welcome to the forum. I was just in London this past weekend... great weather. I hope you also enjoyed it.

      Deciphering mainspring specifications…

      By Knebo · Posted

      I'm surprised you say that.  I'd say that IF (!!) barrel diameter, beat rate and all other things are equal, the length is directly correlated with the power reserve.  A random/quick google search found me this quote from Longines "The length of the mainspring directly correlates with the amount of power reserve a watch has. The longer the spring, the longer the power reserve or also the reduction of the vibration, i.e. from 28’800 A/h to 25’200 A/h. (less vibration, less energy needed)." (https://www.longines.com/en-za/universe/blog/what-is-power-reserve-on-a-watch) A few anecdotal experience on my side would also lead to that conclusion. Then, of course, it depends what you mean by "verry small". In the particular case with an original MS of 300mm, going to 280mm, I'd expect losing maybe 2h of power reserve. Just a "guesstimate".

      Actually one would not claim such thing  about the power reserve without check to confirm this, but if any difference, it will be verry small.

      Another question if I may. When you guys buy watch lots are you buying a mix of mechanical and quartz as well? Most of the job lots I am finding (all overseas) are a mix. If they are all mechanical, it is generally just movements with no cases. I am not at the point where I can identify movements by just viewing them so I'm not inclined to buy a bunch of stuff which will just end up lying around. Is anyone able to successfully move any of the watches they save on to someone else? I can't see a viable market in Australia for refurbished watches. Most people I have seen at work only have a watch if it counts their steps, answers their phone and makes the coffee. I'll admit it, I have a super cheap smartwatch on my wrist. Will I buy another one when it quits? Doubt it. I don't know if I would even bother with a pedometer. Heart rate? And do what with all the data? Blood pressure? Never been right since I got the watch. Sleep? If I can't work out that I'm not getting enough, I need to have a serious talk with myself. I think I'll go back to my Seiko and just make myself stay active.
