Not another oil question!


Recommended Posts

I'm just about to service my first quartz Chronograph its a Seiko 7T92A. I need to do this for a school project.

I've read through a number of the oil posts on the forum but none that I could find talked about quartz movements.

I've got the technical sheets which of course refers to using Seiko and Citizen oils which are near impossible to find.

I've got a good selection of Moebius oils and greases used on Mechanical watches and Moebius 9000 for quartz watches.

Citizen AO-3 and AO-2 is recommended to be used on this movement, AO-3 which has a viscosity of 165 at 20C I'm guessing Moebius 9010 would be a fine substitute with a viscosity of 150.

But for AO-2 I'm not so sure what to use. AO-2 has a viscosity of 58 and my closes oil is 9000 with a viscosity of 100.

Should I buy some Moebius 9030 which has a viscosity of 60? This is to be used on the rotors, or will my 9000 be ok?
