Greetings from the sunny Sussex Riviera (for once this is accurate, at least partially.)
I have a 9ct PW branded John Russel, London - no relation to the well known Thomas Russel I think - with a movement I have so far failed to identify.
It is 44mm (approx) diameter, so around 19'''. My Paulson catalogue has nothing resembling it. I'd appreciate an identification and aplogise for asking the question!
