Up for sale today is my Sinn 356 Flieger Chronograph. I am re-listing this watch as I was considering keeping it, but have decided to let it go to make room in my collection. This is a beautiful example with the Valjoux 7750 movement that runs very well - typically keeping 2-3 s/d on wrist. The acrylic crystal is clear and free from blemishes, and the bead blasted case shows signs of a watch well loved but no deep scratches or gouges. The lume is still in great condition as well. Chronograph function works perfectly. Days of the week are in German. The watch comes on a suede strap as pictured, and I will include the Sinn canvas strap as well as the Sinn travel case. I do not have box or papers. Asking $1200 shipped CONUS payment via PayPal F&F, Venmo, or Zelle.

Sinn Spezialuhren GmbH is a manufacturer of mechanical wristwatches based in Frankfurt am Main. The company was founded in 1961 by flight instructor and pilot Helmut Sinn under the name ‘Helmut Sinn Spezialuhren’.

Following its foundation in 1961, the company focused on the manufacture of navigation cockpit clocks and pilot chronographs and sold these through direct selling, bypassing retailers. The clocks and watches were produced according to pilot Helmut Sinn’s specifications in the private label sector in Switzerland. By eliminating the trade margin of the retailers, the company was able to offer its clocks and watches at a lower price than through traditional sales channels.

In 1994, Helmut Sinn sold the company to Lothar Schmidt. Following the sale, he acquired Swiss watchmaker Guinand in 1996. In 1998, he set up a new company in Frankfurt am Main. With this company, he offered brand watches from Jubilar, Chronosport and the newly acquired Guinand. In 2006, he retired from business activity. Since handing over the management of the business to his long-standing employee Horst Hassler, he now acts as an advisor to the company. On September 3rd 2016 Helmut Sinn celebrated his 100th birthday.
