The key ring “Répétition Minutes” is a handy companion in black anodised, glossed aluminium. An attractive eye-catcher on the front case is a 360° rotating oscillating weight, protected by a round viewing aperture in sapphire glass. The sound of the minute repetition is activated via the button with engraved Milus logo. A deep sound signals the hours, the minutes are marked by a high sound, the quarter-hours by a double strike of a high and a deep tone.
