Vintage Roamer Rockshell MKV day/date in-house 523 automatic 17 Jewel complication with quick set and a hacking feature, a massive 53 hour power reserve, it dates between 1975-76. The watch also manually winds, which is a feature I really appreciate in an automatic watch, it is accurate and has been reliable. A very impressive watch in my humble opinion. 
I love the bracelet that is incorporated into the watch, this is very typical of watch designed in the 1970s, the clasp has the Roamer logo and model name and I love it.
