Christmas has come early, just received a brand new Timegrapher 1900 (cause I've been a good boy and have only used naughty words 99 times a day instead of the usual 200+). Have been looking for lift angles of various Seiko movements but the links to lists have dried up, any one out there have these?

Thanks for the info Bob & extra thanks to Clockboy for one very useful list.

Some seikos in this list.

Nice kit they sell too. No affiliation though.

Few more here among other makes.

The PDFs from this thread above are no longer available. Try:

Also, you can look up Seiko movements here and this reference sometimes has lift angles and technical sheets listed:

It's not a complete list, and I have a hard time finding Lift Angles for some of my vintage Seiko's, so I will add a few more JIC.

- Lord Marvel 5740-8000 (5740C) 53°
- King Seiko 5625-7110 (5625A,B)  56°
- Seiko 6602-7040 (6602B) : 52°
- Lord matic 5606-7190 : 56°
- Grand Seiko 4522-7010 : 52°

Also, understand that if you do watch repair and can't find a lift angle, you can measure this yourself, here is a great doc and video that explains the concept:
