Here is one of my favorite Dynabeat watches, big squared case battery operated +/- 1972 electric.
What a nice watch (cant say it often enough..hehe..)
And just to tease my own eyes, I have put a new band around the watch and displayed it in a
modern Timex box. And the result is a very nice re-issued version
What pictures can do for you
Running strong for me this watch on my wrist today... enjoy !
