The rate readings won’t be affected by the lift angle setting, neither will the beat error.

Good luck, you might need it with an Orient!
Thanks for that. I have today read, somewhere, that some Seiko and Orient movements share a lot of common parts so I am not surprised that the lift angles would be similar.

I did not know that the lift angle wouldn't affect the rate readings and beat error.

It's a school day every day.
Thanks again.
