How should I lubricate this rotor

Recommended Posts

This Bulova has a brass bearing which sits on the steel arbor. The tech sheet says 8300 on the steel arbor. So I'm thinking something like HP1300 or 9501/4. If that is correct would you choose one over the other?

Hairspring coil isn't centered, a bend might help.🧐

Maybe some day, but I've never done that before and I don't want to make this the first watch I try that on. It's already the "first" watch in few categories for me; the first watch I've worked on that I truly care about (it's one of my favorite Bulova watches in my collection), it's also the first automatic and first day complication watch I've worked on.

I need to figure out why I can set the time going forward, but it skips quite a bit when turning the hands in reverse. I'm pretty sure I put the setting wheels in upside down and I confirmed by servicing another copy of this watch that I have and they were oriented opposite of how I put them in, so once I finish up on this second watch I'll come back to this one and hopefully that will sort it.

    • Hi, the cylinder is broken and I want to try to fix it. I don't have any specific tools, so how can I solve the problem? A new plataform or just the movement/pinion?
    • Personally i like to collect old iconic watches, so many made famous by films etc. Or unusual designs.That doesn't especially make them a great watch just a theme of collecting. You've mentioned the Willard, how about a genuine A 11 military watch.  Another iconic Seiko would be the Pogue space watch.  A Citizen bullhead ?.  A grand might even get you a Dirty Dozen, i dont know the availability of these in the US though, an A 11 is more appropriate for your country. Pre Swatch Omega Tissot or Longines , like Richard I'm not a fan of Swatch.
    • Sorry to repeat my question @316lad, but I'm really curious if you could elaborate on why you describe the movement as "a bit of rubbish". My main interest in watches is precisely their movements and so far I have a somewhat limited experience of the ETA movements and that is why I am so curious.  Thanks! 👍
    • Come on members please keep it friendly.  We all try to help. Just think before you start typing.  For what its worth I still say it is a fake the engraving on the back of the case is very amateurish a single word has different size lettering.  
    • Looked up images of natural scenery of quetico park on internet, beautyyyful indeed, I guess no space left for spiders as the place must be crowded with tourists. LWS, we expect to see bigger catch on your future visits.
