I have as a pet project tried to break down the serial numbers of Certina watches as the information is very sketchy saying the least. Some information may be wrong but most is correkt and if you have information that can fill in the holes please feel free to share this information as it will be of great help.

One thing that is needed is absolute facts like a specific year a watch was made som we can pin down the serial numbers of other watches.


Certina serail numbers

Before 1958 the serial number could look like this.

8600-2, 1600756.

I'm not sure the caliber information is in the number as it all over the place and I have not been able to get any real information to break it down, and there were some models that had different serial numbers and some that only hada the production number.



1958? - 1974

This is how a typical serial number looks like from this period.

5806.135, 4993993

58 is the caliber, 06 is the type of metal used in the case, 135 is the case style and 4993993 is the number of watches made.

There was an overlap of the old serial numbers and the new ones sold in 1958 but I don't know how long after 1958 they sold old stock.

Yes there is some good information like what metal a watch is made of so you can stay away from a bad looking chrome watch or if you wonder it you got a gold watch. One odd thing is that Certina put the same high end movements in some lower grade watches so you don't need to splash out a lot of cash if you want the best. So instead of an expensive Blue ribbon you could go for a Waterking, just look for any Certina that starts with 58 and you got yourself a great watch.

Maybe you'd like to hook up with member 'alinghi74' on watchtime.ch. The guy runs the 'Vintagecertinas.ch' site which is, undisputedly, the prime information source on the www as far as vintage Certinas are concerned.

Kind regards
Andreas

Shum,I would love to contribute into your well spent effort,thank you for sharing.We might shed some light into the earlier periods if we find a common ground of information and I can share Glycine serial numbers from pre-1950s,this might help both of us.But we need to make some research and put our information together to confirm.

All know,I collect Glycine; I have verbal information from the 'then owner's son' of Glycine, that the company was bought from Certina.Karl Evilard,is the son of Charles Hertig Evilard who claims to buy Glycine Watch factory from Certina in early 40s. Are you interested in that part of Certina- when it was Kurth Freres,or you prefer to keep it in later time period?

A fantastic project. I wish I could contribute - I did have a hallmarked gold Certina but sold it and appear to have deleted the pictures.

Hi Shum,

I have as a pet prodject.....
Great, but your project not mine. My movement archive just cracked the 9000, and I took this opportunity to calculate the hours I wasted for it. The conclusion: No fürther odd jobs.

So I leave it to you to enter "Certina" in the search box here:
bidfun-db Archive: Wrist Watches
You'll get a reasonable number of Certinas, all with all necessary data to cross check them with your list, and make it more reliable.

Regards, Roland Ranfft

Everything Certina is of interest so anything you can dig up is worth gold.

Here are some 40's and 50's serial numbers. What I can gather is that the last number is the case metal but I believe that the rest is only about the case and not the movement inside.

I have not delved into ladies watches that much as the seirial numbers can be wholly different.

A switch happen in the 3 000 000 range and no more Kurth Freres.

A fantastic project. I wish I could contribute - I did have a hallmarked gold Certina but sold it and appear to have deleted the pictures.
Actually you already have. You made a thread about a Blue ribbon and wanted more information about it but nothing was found. You did find out that the rotor was switched but had you had the simple knowledge about the serial number system you would have found out this faster. I too had some watches that I wanted more information about so the frustration led to this.

I was thinking of hording this information as it's literally worth gold as I have found several gold watches the owners thought was plate. But I couldn't take advantage of it so I told them... So it's better that everyone in search of this information can get hold of it.

Thanks I will. :)

Yes it really takes time an effort to digg into forgotten knowledge.

Edit: I remember now. I started to go through your watches and was stopped at the very first on.

"Case: 5808 102, 5486542, Certina Swiss, 20µm gold plated". I know that 06 is 20 µm gold plated from ads I have read but never come across 08 and so I had to reearch this and forgot about going back.

Sorry, yes. I have been all over that place and bled them dry for information. :)

There seem to be some serials that are off but it could be that someone put together marriage watches.

Well, when I told Bjorn down at the Harbourmaster's Office about Shum's Certina project, he stopped chewing his tobacco instantly, and said "Häftigt!" I say fantastic and thank you for your work on this.

^:-d^

I have made a crude dating system based on two known launches and then added the average (about 350 000) over the 10 years in between per year. This is of course not correct because Certina made more and more watches per year over time and in 1972 they made 600 000 watches per year, but it is a start.

I then addde 500 000 per year until 1972 then added 600 000 untill 1973 when they changed the systenm and remover the information of watches sold on the cases. The highest number I have found on a certina watch is 9713376 and unless they sold new watches with the old system after 1973 it must be from this year.

I added a file at the bottom of the first post containing the same information found there and it also contains different Certina models with serial numbers. It's a good way of finding out when a model came onto the market and it might help anyone out there wishing to do some research.

I had to remove the file as it's to big so if you want it just send me a PM and I'll mail it to you.
Google Drive shared w/Public is a good place to put files too big for WUS. :)
