Offered here is an uncommon Longines “Sei Tacche” (or, “six notches”, denoting the grooves in the caseback), in the largest of the case sizes for a Sei Tacche, 36mm. This example comes with a beautiful white, radium dial, and has matching numbers on the caseback and backside of the top left lug. This Longines watch is in great vintage condition. The case is unpolished and untouched. The dial is beautifully preserved, with no flaws, and light “radium burn”, giving the dial a little color in the center towards the handset. The original radium lume is present on both dial and hands, aged to a yellow color.
