but when it comes to vintage Omegas never say never. a close up pic of the dial would help us determine whether the dial is original or not if you can upload one.
these watches were made specifically for issue to officers in the forces of one of the skandinavian countries, Sweden i think. nice little pieces though more suited to the female wrist these days due to their size.
