Hello to all OF members 😀
I just bought this mint movement with an amazing porcelain dial. I don't have much information about this brand DUNCAN neither about the caliber (the only inscription that has is R44) any idea about what manufacturer made this chronograph . Thanks a lot

Nice beginnings to a nice chronograph.
I'd guess mid to late 1930's from the dial.

A member will be along to ID the movement, I'd guess Landeron

Manufacturer then Location

Hello to all OF members 😀
I just bought this mint movement...

On behalf of the description police, this is not “mint”, as in fresh as the day it was born. Lovely piece, I look forward to seeing how it goes with finding a case, it’ll look great ☕

thanks for sharing information , from what I saw online is not a Landeron. I will keep searching unless someone here has deep knowledge and shares 😀

Could be a Minerva? It has some similarities to this 19-9CH I did a few years ago and this was from 1923. This is a mono-pusher pocket watch so a slightly different layout.

On the dial side, you would see this symbol:

Good luck, Chris

Thanks Chris but looking at both layouts I would say that is not the same.

Yes, he noted that.

Do you have a picture of the dial side of the movement (keyless works) and what is the diameter in millimetres?

It looks to be a Valjoux of some sort to my eyes.

well the size of the dial is 35mm, in case will be a Valjoux which one ?
here are pictures of the side of the caliber. No key , it's a manual winding
thanks

I think it's a Landeron-Hahn caliber (15.5''' possibly), but I haven't nailed it down yet.

I will search for that caliber and compare, thanks Dan

Landeron 15.5''' is getting close.

However, we need to see the movement with the dial off (as in the lower picture) so that the shape of the keyless works can be seen.
These are like the "fingerprints" of a watch movement.

The style of the layout is almost generic and was used by many makers. Valjoux, Landeron, De Praz etc.

The dial (front) side of the movement, showing the keyless works as @JimInOz mentioned. And it would be nice for you to explain your reasoning about the conclusion that it is not a Landeron-Hahn.

Please read the post from @JimInOz, he already explained it very well. Please explain why you think it is not a Landeron-Hahn.
