International Watch Co, Schaffhausen, Cal. 9820, carriage by Richard Habring No. 8, 1993.Very fine and rare 18K gold hunting-cased keyless very thin one-minute flying tourbillon regulator. Four-body, "bassine", polished, gold hinged glazed cuvette. White with Breguet numerals and outer minute ring, subsidiary seconds. Gold "Feuille" hands. Notes In the early 1920's Albert Helwig, technical director of the Deutsche Uhrmacherschule invented what is now commonly known as flying tourbillon: "…My idea of constructing the free-standing cage that is without a bridge, was to make a tourbillon as flat as possible … The weight of the cage is only 700 milligrams; no one believed that it would be strong enough. Therefore, I tied a string on one side of the cage and another one on the other side but with a weight of 250 grams. I then hung this in thdisplay case at the entrance hall to the Deutsche Uhrmacherschule and left it hanging there for four weeks, which stopped all critics…"This is the thinnest of all flying tourbillon pocket watches that we know of.
