This my late grandfather's watch, a none runner when given to me, cleaned it up, polished the crystal, new strap and after a lot of tries it now runs.
Any information about this type of watch and struggling to set the correct time/date, crown pulled to first position adjust the time in reverse to modern watches but I do not want to force it further out.

The pictures are too small to be of much use. Seeing a clear picture of the movement would also be helpful.

I agree. Cant tell much from those pics but... try turning the crown a few turns in each direction before you pull it out into the first position. Some movements with day / date features allow that to change each independently. It may only work for the day and you will have to wind the crown in the first position to move the date forward. In those instances you can usually wind the time past midnight to about 2am and then wind backwards to about 8pm and then forwards to 2am etc to change the date faster.

I believe 'Corvair' was a sub-brand produced by the Langendort Watch Co of Switzerland back in the 50's thru the late 1970's

The dial says 25- jewels and the movement rotor says 17. Looks like the movement was replaced? Good looking watch regardless.

Good catch! I'd say a replacement movement is an excellent guess.

Many thanks for taking the time to answer my inquiry.
If I could figure out how to change the date (easy/quick way), ccw changes the date only, cw changes both together. 8 till 2 trick does not work you have to do full 24hrs rotation so I guess by going backward and forward you could get them to be the correct day/date. CW to the correct date then CCW under the correct day is reached.
It's was my Grandfather so happy it now runs, it looked very sad when I was given it by Mother, now it is wearable and does till the time without stopping.

I have a couple watches that do not have a full quick-set date feature. Kind of a bother but that's just the way they are. I set the day of week first and then bring the date in-line to be correct for the day. Part of the "fun" of owning a watch. Enjoy yours.

Tried again just now and it does flick the day over using 8-2 method and the opposite direction to get the date correct.
Once again thanks for help given.

Glad to hear you figured it out. I agree with SFwatchGuy. Someone has replaced the original 25 jewel movement in that watch with another that fit. Corvair used a variety of watch movements so we may never know what the original one was.

And don't forget to have it serviced regularly!
