Here is a very interesting one...

A buddy asked me if I had ever heard of this racing team and then showed me this watch.

1980-1983 with these specs, but the movement dates to 1972, which makes the movement insanely interesting.

Automatic
Column wheel chrono
Flyback
Day Date
28,800 bph
100m WR
Black PVD case or Titanium...
Bi directional Bezel with count down and compass markings, and internal tach markings.
Promethium 147 lume

To me that's very very impressive, but it gets stranger.

It did not have the watch companies name on the dial, but it had a Former F1 racing Teams logo on it, one that was no longer active... (OK this may be wrong as the same source claims the movement was from 1972-1980... which puts it in production in the 3 years the team was in F1)

Oh its a Citizen...

Even outside of the production period. It’s an interesting watch and a very interesting movement I was not aware of.

As for the source.. he appears to contradict himself alot in various articles... So the dates may not be correct, or the team may have still been in operation for a few years in support of support for other mfg's. Much the way Lotus ended up doing work for everyone and anyone for awhile.
