A couple days ago i bought a used Certina quartz watch where it seems that the dial and the rest of the watch does not match. On the dial itself it says DS N2, but a quick google search leads me to believe that the casing is from the prior N1 model. I'm trying to figure out the reason for this. It seems to be a lot of trouble to modify a watch like that yourself, could it be a transition model where older parts gets used? I am completely lost here, as well as in the world of watches altogether. I really like the watch though, and am interested in getting to know more about it.
Here is the info i managed to find on and in the casing:
184 7000 41
ch 2540 Grenchen
It should be from around 1980 (?) and the designer is Roger Tallon.
I would love getting some help in understanding and getting to know this watch a little bit better!
