1966 Accutron Spaceview

Here we have a 1966 Accutron Spaceview 214, Chapter Ring style. This is an original Spaceview, not a conversion that you see many of. It keeps good time, although I do not know the service history. The case measures 34.75mm in diameter, 18mm lug width. It has the initials "MG" engraved on the back. I have it on a vintage gray Kreisler 11/16" strap. I'm asking $525 or best offer. Returns accepted if not as described. Plenty of positive feedback on here and other forums. Please PM me for inquires.
Thanks,
Matt
