So I'm at the point where I'll hopefully be putting together all the clean parts of a Seiko 7009a movement. There's the famous service manual online that provides a lot of great information about reassembly and lubrication, but unfortunately the lubricants listed are ones I do not have access to. Namely: 

  • Moebius A
  • SEIKO Watch Oil S-4
  • SEIKO Watch Oil S-6

I have the following alternative lubricants:

  • Microsgliss D5
  • Molykote DX
  • Moebius 8200
  • Moebius 8217
  • Moebius 9415
  • Moebius 9010

I've numbered all the lubrication points in the service manual (hopefully I've not missed any). I've read a lot of forums and watched a lot of videos on the subject, but it seems like there are a million ways to skin this cat. Below are the numbered lubrication points from the service manual (in red) along with the Seiko recommended product and my plan for alternatives. Let me know if I've made a mistake or if there's anything I've missed.

In regards to the barrel and mainspring, I was planning on 8217 for the barrel walls and an extremely light coating of 8200 for the mainspring itself.

 

As you can see there are loads of points that I'm missing info on, and frankly I think I'm just confusing myself even more by reading more information. I've checked a Moebius lubrication guide, this forum, other forums, etc.


Any help filling in the blanks would be greatly appreciated.

Moebius A

This is an abbreviation of the real name. The first part tells you who made the oil the letter a refers to a specific type of oil that went with the name of Synt-A-Lube. If you look at the website you also find they have numbers and this is known as 9010 which I believe you said you already have.

Thanks @JohnR725

So ostensibly I could just replace Moebius A everywhere it's used with 9010?

With regards to the pallet stones, those should be 9010 also or 9415?

With the S-4 and S-6, what would be the best equivalents?

I'm thinking D5 as an alternative to both?

Yes because the exact same thing. I'm also attaching a PDF of a slightly different Seiko showing how to lubricated and their lubrication choices.  The other thing to do you find a really new Seiko watch and see what their lubrication choices are just because people like to change especially watch companies.

Here's a recent discussion on Seiko lubricants

Here's a much older discussion with interesting images that might give us some helpful ideas. Then for the S6 I'm guessing from your list D5 would work fine.
