Yesterday's Financial Times had one of their Watches & Jewellery specials yesterday and one of the articles is about a specialist at Phillips called Paul Maudsely. A Mulco Prima Tri-Compax appears to be one of his favourite personal watches and I can't help thinking it bears a rather striking resemblance to the UG equivalent. https://www.ft.com/content/1485af56-1954-11e7-9c35-0dd2cb31823a The watch (including better pictures) appears elsewhere on the web. https://www.revolution.watch/collec...ps-watches-international-specialist-director/ He refers in passing to the fact that it is often mistaken for a UG in this video (from 12:47) https://www.pageandcooper.com/blog/one-to-watch-paul-maudsley/ Unfortunately I can't find any reference to who might have made the movement. Does anybody else think it's a re-badged UG?
1950's time period.. Looks like a duck... quacks like a duck... Considering the darker Mulco Prima logo, I'm guessing it's a re-badged UG Tri-Compax.
One difference between the Mulco and the Breitling is that the former is not cased in stainless steel.
There's only one quick set because you don't have a day/month indicator - the quickset on the Venus only deals with the moonphase. @DirtyDozen12 Isn't the Mulco in stainless steel? It doesn't look chromed to me...
The back is marked "Fond Acier Inoxydable". In one of the images above, you can see that the color of the stainless steel bracelet appears warmer than the cold, chromium-plated case.
Why not "Bi-Compax" since one of the complications is not present? Or why not leave the "Compax" nomenclature out at all, since it is an unrelated watch, mechanically speaking?
