From 1960 to 1971, only 8821 mechanical chronometers were produced at Certina. All with the 25-65 movement (without date) or 25-651 (with date). The movement has a unique serial number which must match the one on the case back.

Dear OF members,Hope you're having a great holiday season!Today I had the pleasure to receive from my grandmother, my grandfather's watch: a vintage jumbo Certina from early 1960s. Reference number is 8002 017 and serial number is 4736023.I've just started researching and collecting watches and there are no words that can describe how ha ppy I am for having inherited this watch, a watch that my grandpa winded even the night before he passed away around 10 years ago.This is actually a watch that my father received as a gift for his first communion in 1963, along with another one. He decided to wear this other watch until the day in which he had a sort of argument with my grampa that resulted in the watch being broken.I don't know for which reasons, maybe my father did not even remember the existence of the Certina at that time, but this watch remained unworn until the day in which my granpa's watch stopped working, and my father gave him his Certina that he wore it for around 10-20 years.This watch has remained in a box for the last 13 years, until witch my uncle's one, a chunky Breil, stopped working and my grandmother gave the Certina to him.

He wore it for three months and then gave it back to her because it was aplaerently not working.Lucky me! Long story short, today I went to visit my grandmother with my father and collect the watch.

My father had no idea of which watch I could find at my granma's place. He only told me that I could find a vintage watch that he received in 1963.And this is what I found! I'm in my early days of collecting vintage watches and this is actually only my second one, so cannot really comment a lot regarding specs and condition.What I see here is a (probably) all original dial in near perfect condition with applied markers in rose gold (plated?). The plexiglass has a big scratch at 6 o'clock and various smaller others all around.

The chromed case (argh!) is not in great shape and it seems that the plating has worn off in many points. Lugs look super sharp to me and I think the watch has never been polished. The case back is in perfect condition with no scratches and all numbers are clearly visible. I don't have neither the original staple or buckle, nor box and papers. The crown is unmarked: maybe is this a replacement?I haven't opened the watch (never done it) and couldn't find information about the movement, number 80, in the Certina database. Despite what my uncle said, I managed to wind the watch that it seems to run!!!!May I kindly ask you what are your thoughts about this piece?

I want to keep it as original as possible, but is there anything I could do to remove at least the green from the case? Which kind of service does the watch need?Thank you very much!K. Great first post! Very much a delicate piece.

Take it to a reputable watchmaker and ask them to perform a movement service only, as well as just a clean on the case with no polishing. Ensure that the hands and markers are not relumed (if they have lume.) Ask them to change the crystal, and to provide you with all replaced parts.

The plug in creates some very interesting and strong effects on your.Thread Anything like the 'Fractalius' Photoshop plug-in.Now using fulltext search.

If so desired, you may ask for a replating of the non chromed areas. From a sentimental/originality point of view this does not need to be done however.Certina were an excellent brand that offered many watches that compared well with Omega at the time. If properly serviced your watch will hold a 38-40hr power reserve and keep good time.I wouldn't worry too much about missing box and papers - what's more important is the watch itself. I also wouldn't worry about the crown being unsigned, as it appears to be the same age as the watch (and could also be original to the watch.). Thank you very much! I have a cousin who is a watchmaker and will try to arrange a meeting with him today.

Unfortunately, we live in different countries but we're in the same one at the moment!Thank you very much for you very valuable inputs! I'm glad to know that the crown might be original - I will do a bit more research on this and keep you posted on this. Regarding servicing, you mentioned exactly the things I had in mind.

I don't fancy the idea of a replating - I want to keep the watch as original as I found it.Thanks for the great advice! I will not wear it then.Thanks for your great input on the movement! I had a look online and found a youtube clip of a Certina very similar to mine with a 28-10.

It has same hands and a very close serial number in the 4.5. 5.0 range that dates the watch to the same year, 1963 (. Thank you very much!
