Here's a vintage chrono you don't see every day: a 1960s Bessa Prestige Chronautic.
Slate gray dial with red and blue accents, red chrono hand and that amazing ocean-blue bezel.
So. Freaking. Cool.
This looks like it was carved from a solid slab of stainless steel, with sharp edges, original polish, planed angles and a UFO shape.
It's a huge 48mm across, excluding the unsigned crown... by 48mm from recessed lug.
Crystal excellent. Bezel is fixed.
Under the hood is a Valjoux 7736, keeping excellent time. Chrono functions are fine.
You think you've seen this? You haven't.
