This is a very rare and unusual Milus double retrograde mechanical watch from the 1970’s. Case measures 36,5mm without crown, 40mm lug tip to lug tip and height is 11mm.   17 rubis Swiss hand winding mechanical movement. Watch is fully functional and works fine.   There is hardly any information about this watch. The idea is identical to the Wittnauer Futurama and Lip Linear as they all utilize the same retrograde module fitted to a mechanical movement. In the Mius the movement is a high-grade manual 7046 calibre by Peseux that was fitted to many top-shelf watches of that era including Girard Perregaux and even more notable brands. The movement can easily be replaced from any other watch but note that the date disc is printed at a slight angle, however a generic date disc will also look presentable.   The Milus is different than other design as the dial markers are printed in a different layout. Hour 12 and 0 minutes are placed in the center thus the hands do not jump at midnight but at 6:30 what I find a bit akward. When assembling the watch you will be in for a surprise if you forget about this difference and set the date to change together with the jump of the retrograde "cranes".  Matching the date change with the hands is difficult on the Wittnauer and Lip but the Milus is even more tricky and might require a few attempts.   Watch is the same as the Difor discussed were: www.crazywatches.pl/difor-secteur-retrograde-jump-hour-1972   Guarantee on originality and on satisfaction.
