The Longines reference 20 736 here offered is part of a very restricted circle of timepieces: the 37 mm three body case with snap on back and smooth sloped bezel has been realized in stainless steel and preserved in surprising conditions with the massive concave lugs give strength and security. This very lot is special since is a monopusher “double hand”. This nickname comes from the red hand clearly visible at the center of the dial, which is the one in charge to allow the owner to control the registration of minutes with the aid of the internal scale for 60 minutes. Totally unconventional, this complication is moved by the caliber 12.68Z with the chronograph complication activated by the square mono pusher at 2 o’clock. The argentè dial is nicely conserved with outer Arabic five minute divisions, inner minutes track, Arabic painted numerals and pencil hands with luminous materials. Another main peculiarity is the subsidiary dial for constant seconds at 6 o’clock instead of the 2 classic registers.
