1930s Tavannes Stainless Steel 35mm Flexible Lug Chronograph Sector Dial

This is a rare 1930's Taban ss 35mm flexible chronograph with the popular sector dial. The cylinder case is one of the rarest and most unique of the many variations of the flexible case, and is much larger than the 35mm case size. The dial is a rare and wonderfully designed sector dial with mirror circle, telemeter and snail tachymeter printed on it. The watch is equipped with the Landeron 39 movement, a prestigious movement made by Landeron, a manufacturer of chronographs and a supplier of machines to many brands.
