Hi Folks

I have just acquired the above pw and would like some info on it if possible please. I am interested in when it was made and any other info you can tell me. The style is from the 1960s-1970s, perhaps!

There is no serial number on the movement. There are numbers on the base plate under the balance wheel - U
6431
6445
86 or B6 Caliber numbers perhaps. The U stands for Unitas movement? The case is Nickel Chrome.

The original box has the following number underneath - 99.50.02

I have attached pics.

The trademark under the word rotary on the dial may give a clue if we can have a clearer picture of that please.

Hi Stephan

Photo of trademark as requested.

I am still new at this but here is my attempt
Page 643 of Trademark book

WA = watches. WP = Watch Material Parts.
SUP = General supplier to watch industry.
JL = Jewellers Shop

It's close, It's Swiss, but not sure if I will get a cigar.

Hi Stephan

Thanks for the info. I will follow it up.
