Productive Saturday a few months ago, bought a box of odds and ends and amongst the chaff I found some wheat.

What references will these two crowns pair with?








BONUS

Also a few buckles





Thank you in advance

 

Hopefully these crowns are not for a women's watch.

 

Seamaster De Ville ?

 

Two-piece crowns, so monocoque cases.

...Right? I'd be very surprised if they were for women's watches with those diameters.

 

Thank you, any other way but trial and error?
