The latest of my Ultra gang arrived this morning, an Ultra "Racing". This is the first Ultra "brand" I've come across other than those using the usual calibre spec, (41, 602, 904) or those marked as "Superautomatic" or "Auto Calendrier". Also, this is the first actual Ultra I've come across not using an Ultra in-house movement, using a 17 jewel Parennin HP 60 instead.
Andreas at Mikrolisk shows C.I.H. as an Ultra brand, but I'm not so sure, as it probably stands for "Compagnie Industrielle Horlogere", which in the context of advertising, which courtesy of Cellar I've actually seen, just means "watch making company".
