8 day "clock" movement

[datikiman]

Hi all. new to the forum. hoping it will lead to more learning opportunities. I'm Nick and I'm a self-taught watch repairer - not yet a watchmaker! - with 6 years of learning under my belt. I'm a member of AWCI as a hobbyist. I'm sufficiently competent to offer repair service for many mechanical & most quartz movements and have been doing so for about a year now. Not sure if this is the proper forum category and if not kindy refer me to same.
The latest piece to come to my bench is a deco-era Gubelin 'pendant wall clock'....essentially a large pocket watch. Extremely little info is available and as I'm finding out, Gubelin is more of a jewelry maker than watch manufacturer. Anyway, I have the movement out of the piece and now trying to determine the caliber make & #. any help in that is greatly appreciated.
