Thankyou for the response. Countdown Timer Ppt Crack. I have been looking at Dr Ranfft's archive which is organised by calibre and does have some example serial numbers for the particular calibre. I was hoping to find whether Cyma's serial numbering system related in anyway to the date or calibre. I'm used to the Seiko system. I am having trouble posting pictures to the site. I have posted pictures before but something must have changed. I'll need to read up again on how to do that.

Rob Hi Rob No, very rarely do we have serial numbering to caliber type (Hamilton does) So you have to search painstakingly through each movement, and being a bit of an expert as Roland surely is. We can usually narrow down to a date by style of face and/or movement Try posting pictures regards. Is there a way to identify the calibre from this number? In a mass-production environment, serial numbers are usually assigned 'runs' or blocks of numbers, and usually all the watches produced in a single run will be the same caliber. The NAWCC waltham database (which is based on factory records), in an example of such as system, and since the factory records were available, we can (usually) tell what a Waltham is just by the serial.

I recently had a query on dating these movements so have posted the answer here so I'll not have to do it again.
The serial number on these movements are under the dial as show to the right. My dating is based on a reasonable number of watches, listed below, in hallmarked silver or gold movements. The sample is heavily biased to watches retailed by J.W. Benson, largely because other retailers frequently used Swiss hallmarked silver cases which do not carry a date mark. Benson appear to have switched from Revue to Tavannes in about 1932 the database is only good for the 1930s.
It must be remembered that a movement might not go straight into a case which itself may have been on the shelf for a while so there will be some overlap, also the hallmarking years of the various assay houses are not in line with each other or the with calendar but the difference is small and the date is likely to be accurate to plus or minus a year.
