Hello. Does anyone recognise this zenith Pocket watch movement please? Thanks in advance.

Have you checked on Dr. Ranfft's site? Measure the size, in lignes, and scan the right column for matching sizes. You then look to see if it says "manual wind" in the center. Then look at the images. You'll probably find it. Good luck.

(I see that you're pretty experienced, so you probably have tried this. Sorry if it's so obvious.)

Hi Mr Roundel. I’ve been taken directly to dr ranffts site before when searching for a known movement I’d, but to be honest I’ve never looked at it from the perspective of using it as a comprehensive, searchable data base. Thanks for the tip. I don’t consider myself to be experienced by a long chalk in comparison to some of the longer served folks on here - but I’ll try not to let the compliment go to my head :-). Thanks again and I’ll keep you all updated on what I find out.

Regards

Still scratching my head with this one. I have found Ranfft to be useful, but photos showing the correct dial side don’t have the same cover side features and vice versa. For clarification which diameter should I be measuring for the calibration in lingne? Thanks in advance

You should measure the maximum width of the movement in mm then convert the measurement into Swiss lignes there are online converters that will do this for you many of the early zenith calibres only have the ligne size as the calibre number , the serial number on your watch suggests a production date of a round 1915.

Thanks for your help WLS. I had intended to initially add the photo, but..... anyway, thank you. I’ll work with the overall diameter marked as black

What you have shown is the height of the movement you need to measure across the dial side of the movement to get the measurement

[wls1971]

Sorry I have misunderstood the photo you have shown yes the line you have shown in black is the point at which you need to measure across as that would be the widest measurement
