In addition to being an homage to Robert Mühle, Mühles’ special edition features a complication never before found in a Mühle wristwatch: a newly-designed Auf/Ab (up/down) display. The round scale of the up/down display, which is open at the top, is located at the 12 o’clock position on the silver-coloured dial. It shows the watch’s power reserve, namely the amount of time left before wearers need to rewind the movement. The movement of the Robert Mühle Auf/Ab has a power reserve of 56 hours when fully wound.Reference M1-11-15-LB has a silver dial and is fitted a black crocodile leather strap.
