Help identifying this Certina

[Igami]

Hi,
I’m new here so I hope you are going to look over my novice “language”.
I have a Certina watch that I don’t know so much about – I searched over the net after the numbers that are printed on it but could not find any details. So hopefully somebody can help me. It’s a very small watch – the diameter is around 1 cm. The person that sold it said that is an “old fashion” watch BUT I just love it. So really hope somebody have more info on this.
As I said a Certina lady watch with “flexible” bracelet (metal gold colored with the text “Speidel USA” on the back).
On the back of the watch there are2 types of numbers: the first one looks like the manufacturers marking: 0806 883 7068362. The second one looks like a hand writing 64804 85.
On the lateral of the watch on the side with the “key” are 2 inscriptions: “20” and a “KB” into a sign that looks like a horseshoe – sorry for the description…
The gold metal on the watch looks like gold but I’m not sure considering that I don’t see a stamp anywhere.
Hope that somebody can tell more about it.

Thank you in advance!

Looks to be early 50's to mid 60's vintage. 7068362 is likely the individual serial number, 0806 883 is the case and/or model reference number. Certina is a respected brand going (in one form or another) back to the late 1800's. A photo of the movement might help a little; your best bet is to try over in the vintage forum, take your watch to a good watchmaker and have him/her look at it, or email Certina directly. Many watch companies have archives of their previous models and most are happy to help you with info. Pretty little watch!

I don't know anything about vintage Certinas, but the design prompts me to date it a bit later than Sherry's range - I'd say late 1950s to maybe early 1970s. That bezel and general geometric theme reminds me of what Hamilton was doing with its men's watches from about 1962-1970. Could be earlier, but the late 1950s non-conservative styles tended to be "spiky", for lack of a better description (think starbursts and narrow triangles rather than blunt squares/rectangles).

If the bracelet isn't original (I suspect it isn't), I'd suggest ditching it in favor of a smooth or very subtly textured one. Either replace the crystal or give it a good Polywatch scrubbing. The patterned bezel is gorgeous and deserves to be showcased!
