Stumbled across a vintage Unichron diver chronograph at a watch shop today. Looked not that bad but can not seem to find much about the brand.

Have found a few pictures but not a Diver Chronograph. Mainly a black dial with a red 5 minute marker on one of the chrono dials

 

One of many brands from the halcyon days before quartz. IIRC, some were powered by a Japanese mechanical movement.

Got any pics?

 

No couldn't get a pic of this one. Had a nice Omega but was with a few others so couldn't spend much time.
