Thankyou in advance to anyone who can help..
It is a manual wind gyromatic, (womens I believe, going by size) 26x24mm, apparently c.1970.
I am just trying to find out a bit of info about the model type as I haven't been able to find another like it online.
I Bought it for au $280 on ebay, not intended to sell, so I guess if I like it, then I didnt get ripped off in my eyes! Any additional information about this watch will be fantastic.
Thanks

looks like a pullout timepiece and open thru glass, so you cant easily see the caliber except by removing the dial. design is similar to my gp gyrodate auto, but runs pretty good time. probly a full wind will last 4-5 days.

Doesn't Gyromatic mean automatic?
Nice looking case.

Thanks. gyro is auto. if you have one, try to wind it full and just leave it on top of the table. observe how many hours or days its power reserve will last. the gyrodate is 39j and tested it as i said after being fully wound.😉

I'm still new to this watch business and learning every day.. by new I mean this time last year bought a CLUSE as I liked the minimalist style and that was it. I literally had no idea about quality glass types, movement, quartz vs auto etc. Have since moved on to a longines charleston, Tag Carrera quartz and now my first gyromatic/ automatic.
Please forgive my ignorance, how much is a full wind? I wound it a few times and it continued on for about 12hrs, losing approx 2mins in that duration. After a little shake, it continued for another couple of hours.
I also just received a couple of pics of the inside from the seller

Thanks again for your response, I love your gyrodate dial

My GP is definitely in need of a good service, I have no idea of its service history..
Would it be sacrilage to consider a redial? Or maybe just a slight clean up to remove any dust/dirt particles to ensure its longevity?
I think you're right about the pull out timepiece.. might explain why the glass moves/ jiggles slightly when I push at it

I would leave the dial alone. It's not that bad, IMO.

Great find, thanks for that! I was thinking that it could possibly be a '68 or '69 version, being a gyromatic and the overall style.
I think I will leave the dial as is and just be very careful wearing it. I think it may be prone to water or moisture getting in, due to the movement in the perspex glass
