C Citizen Phynox rectangular watch

Today is probably the oldest Citizen watch I've blogged so far.

This watch is one of a Citizen range called Phynox. The Phynox range seems to have been released in the 1950s, and ran into the 60s. I've not been able to find out more about the history of the range, but there are a few other watches that are for sale from the time period, and they all seem to be hand wind mechanical models.

This watch uses a Citizen mechanical movement. It doesn't have a listed number of jewels on the case or on the movement itself, but the movement was adjustable if running fast or slow. The watch has a 2 hand main dial, but has a secondary dial for the seconds at the 6 o'clock position.

The dial is a rectangular design in gold, with a C symbol above the Citizen name and the Phynox name above the rectangular seconds dial. It comes with a matching gold coloured metal chain strap (part number 1BGF).

There are a few pieces of information on the watches back. It mentions 20 microns C.G.P (which I think relates to the gold plating), and there is the word star in a box too.
