White Dial UG Microrotor Calatrava
Universal Geneve Microtor Calatrava
“Super-Microtor” Automatic Movement -- with a standard size rotor. ;-)
The caliber 256 by UG is all correct and original but somehow easy to misunderstand as the rotor is not really micro. However, a beautiful automatic in a fantastic and probably unpolished 18K gold-case with a white dial -- we mounted a eggshell-white strap but are happy to provide a black one instead.
