Limited Edition of 250 Timepieces.. A special treat for watch lovers is the limited series of black PVD coated watches powered by the calibre, Unitas 6497. Glycine has devoted particular attention to the design of the dial. The dial is a wonderful construction on two levels with extra-large second display at the 9 o’clock position. Two hundred and fifty pieces of this classic contemporary watch have been made. The origin of the KMU 48 goes back to the well-known military watches of the last century. Glycine launched the first replica of such watches as early as 1999. In the meantime, demand has grown so strong that the KMU 48 has established itself firmly as a distinct family of watches in Glycine’s proud collection.
