Citizen/Miyota 8210 Setting Lever Question

JimInOz · Mar 5, 2026

I'm in the process of servicing a very well worn Citizen diver.

Managed to disassemble everyting without drama, but the setting lever has me at a standstill.

In the pics below you can see the setting lever in normal position, and then in the stem removal condition.
The setting lever axle can only be installed from the top of the plate due to it's shoulder.
The setting lever cannot be removed from the axle using normal "force".

I suspect that the setting lever is swaged to the axle so the assembly becomes one piece.

Can anyone confirm?

I don't really do Asian watches, but just based on the photos and your description, it appears this is not made to be disassembled.

It's not completely unusual to see parts that move/rotate that are not designed to be removed during a normal service. I can't say that I've seen it for a setting lever that I recall, but I've seen it on various movements before - the one that immediately comes to mind is the ETA 7750:

This lever for reset of the chronograph is pressed into the bridge and not removed during service, yet is requires the lever to pivot much like your setting lever.

I would try to get some oil in there (9104), but otherwise I'd leave it alone.

Seiko chronographs have both of their buttons permanently riveted on as well, you're supposed to do exactly that: get some oil/grease in there and move it around a bit. I DO note that the disassembly manual doesn't show the setting lever being removed, and doesn't show the other side of it at all:

Thankyou both.
I suspected as much but experience has taught me, when in doubt, ask questions.

Another interesting (to me) are the balance jewel settings that Citizen used.

And of course, the upper cap jewel is different to the lower, although the "spiral spring with jewel" is identical.

Note that the pic is before cleaning.
