I have this 1940s? Mulco chronograph needing a crystal. The one that came off of it looks like it had been chewed on at the edges and was sort of loose in the case. Can someone tell me what is a proper crystal for a watch of this type? I did measure the diameter of the inner bezel that it fits into at 32.5mm. The watch itself is about 38mm diameter. I am guess a straight sided crystal is not appropriate? Did any of these have actual glass back in the day?
Thank you for any help or advice.SaveSave
