Hello Federico. The watch is from ca 1950 and it was a cheaper model as it's plated and the case is in bad shape and the only way to make it useable is to have the case replated. It looks to have fixed strapholders and I recommend to remove the bracelet and put on a fabric of leather strap instead as metal bracelets wear down the lugs.
Mar 24, 2015 - Re: Certina serial number system. Hi Thanks very much. The first one looks just right - send me your details by PM and I'll sort the dosh out best. Certina serial number system 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.
Thanks a lot!!! The bracelet is broken, so I've decided to change it.
The clock delays, maybe because it's dirty. I'm looking for an old school profeddional here in Murcia to clean it. I'll ask him to replate it too. Thanks a lot!!!

I'll ask him to replate it too. A watch need to be service at least every 5-7 years so the oil is old and usually a good cleaning is all it takes for these old watches as they were made to last. The old chrome must come off and the case polished before new chrome can be applied and this costs a lot of money and not everyone can do this. Hi, as a newbie I post my question here - if this thread is wrong, mods can please move it. I've got a Certina that does not seem to match exactly the criteria mentioned in this thread: Face shows 'Certina' in new letters without logo = seems to be produced between 1954 and 1958 Back shows serial no. '4293 9' = age seems to match; the '9' is obviously for gold case (inside stamp '14K 585'); the '4293' I can't interpret. The movement seems to be from another time: 'Certina (with logo) 25-66', that is described as from 1960 or later.
Does anybody know anything about this kind of watch? Is ist a fake? Was the movement replaced (there is an unreadable Hallmark on the inside)? Did they deplete old cases with new movements? Certina gold watches use a different system but it could be a non Certina case. This type of case was introduced in the early 60's and is used to this day so age is hard to say. The movement looks to be an early 70's 25-66 with a 2-spoke balance wheel but the dial logo looks more from the early 80's and the movement holder washers don't look like the ones normally used by Certina.
On smaller and special watches Certina didn't always use the little C inside a C logo and just the name so it could be an all genuine late 60's to early 70's watch but the serial number on the caseback is odd. One cold order gold watches with special engravings so it could be that the number isn't a Certina number except the '9' and might have been a serial number for a big company or government agency. It is a nice watch what ever it is though. Good morning Shum Hope you are fine! Here's another piece for your database.
I bought it from the son of the primal buyer. It's a Certina 288, Ref.
Serial number is: 8275839 - Should be produced around mid of 1971. The certificate of warranty was issued on january 12. Half a year in between production and sale. I would say that's another hit! The cool thing is; I've recived the watch yesterday, exactly 44 years on that day after the watch was sold! Furthermore some more serialnumbers of different 288 models: Ref. 5901 800: 7'574'935 7'577'526 Ref.
