This watch has been in my project bin for a while and I finally got the crystal replaced, dug up a 16mm strap, and decided to wear it today. It's a Swiss made Benrus. It's only 32mm (34 at crown) diameter. I thought it would be too small, but it seems to look OK to me. I am thinking early 60's just by the style, sorry no pictures of movement. Keeps good time and the lume still glows, but no for long. (Must be the bad stuff, right?) Not bad for 40 years old. Just thought I would share.
