I don't think I've shown this one here, but I'm wearing it today - a 1968 (according to the movement serial number) Ref. 8022 on the original bracelet. I was really happy to find this one, because I had been looking for a square UltraChron for quite some time.
Another favourite today. This one thanks to @Laneside in Scotland. This 61 year old watch brought back to life with a replacement movement. A feature not often seen on this model………a gold shell case. Every time I look at it, I am hardly able to believe it is as old as it is. I suspect a previous owner gave up on it after it proved troublesome, and was unable to find anyone to repair it (quite a common problem with Accutrons).
