Hi, I'm a total newbe but i am enjoying this a lot! I am starting my new hobby by working on Seiko 6309 divers.

My question is: Seiko calls for 4 kinds of lubricants. Moebius A, Moebius V, Seiko S-2, and Seiko S-6. What are the commonly used lubricants?

I have seen synt-a-lube and others in Marks videos. What should I be using as substitutes for the above?

Thank you for your help.

Hell there...

I'm not the expert on this, but there are several threads on lubricants. I mention this as it is like discussing politics at a dinner party... It may not go over well.

But, I do believe you can refer to the Mobeius lubrication chart and be fine. Watch will require re-regulation but that's normal anyway.

Good luck!

Depends on what you're lubricating.  High grade watch movements are pretty specific and you can look them up by manufacturer.  But the same manufacturer (e.g. Rolex) may have changed their specifications several times.

For most of what I do--none of it really high grade as well as old pocket watches--I use Moebius 8000, HP 1300 and 8200.  Henry Fried says you can use Vaseline in place of 8200.  For old pocket watches they used to use, among other things, sperm whale oil!  (My former instructor who has everything of historical interest to the watchmaker had some!)

I don't think a Seiko 6309-729 or 7049 case would qualify as a "High Grade Movement." But I have to say that I think they are the best to start working on. Their simplicity makes them easy to work on, and their accuracy can be pretty amazing. But you have to kiss a bunch of frogs to find the really great one. The Barrel arbor and the baseplate seem to really get worked over. So I have ended up with 4 or 5 movements to make one really good piece.

I want to start working on Eta movements soon.

Thanks for all the help. I look forward to signing up for the courses.

ETA’s are fairly easy, and parts are cheap too, so unless you get something really old they are great to play with. 

But the easiest movement I’ve torn into is the Rolex 15xx movement. It’s sort of a kin to a farm tractor. Simple, and overbuilt. Low beat by today’s standards but quite accurate. Generally, if not broken, just clean and lube properly. I like them. My only 3135 experience is a replica movement so I reserve judgement on the real deal.

      Introduction

      By Randy55 · Posted

      Welcome to the group Stirky. You can search for just about every subject in the craft here. Don't be afraid to ask if you can't find the answer that may have already been covered ( some ad nauseum LOL ). You don't have to buy Bergeon to get good quality. There are many decent mid-range tools available that will last you a lifetime. Cousins would be a good place to start . Cheers from across the pond ! Randy

      What are these Seitz B-Jewels?

      By Jon · Posted

      I picked up a similar amount of these jewels some years ago in a watch and clock fair. Every now and then they come in handy. This week I've got a rubbed in bombe jewel in the balance cock that is cracked and needs replacing. Very handy to have a vintage assortment of these type of jewels!

      Diagram for 6497 motion works

      By Jon · Posted

      Great diagram with the teeth and pinion count. Simple way to reduce the speed of the hour wheel by the 12:1 minute wheel. Genius and yet so simple. Always good to reinforce the principal by what you have done in your drawing. Keep doing that. I had a drawing on my wall for years showing me this which is very similar to the drawing you have done. Here's a formula to work out the beats per hour of a watch movement. The movement's BPH is dictated by the wheel teeth and pinion count and the hairspring being vibrated to the correct BPH by finding the pinning up point on the hairspring using a vibrating tool.  The reason in the formula there is X2 on the top line is because there are two pallet stones.

      So I just wanted to say "thank you" again.  The angle is the key bit it seems and yes, it did basically just fall, or float, back into position when I got it lined up just right. I had meant to add that now that I see how it goes in, I totally see how it came out in the first place, and that whomever cloned the original movement didn't pay much attention to the fine details around the setting or how it interfaces with the balance cock or the "rings" on the regulator and/or stud carrier arms.
