Hello WatchEx! I am selling my Sinn 556A that I've owned for a few months. If you know, you know; the 556 is that perfect 38mm daily driver that's understated enough to match any attire, yet rugged enough to handle anything you throw at it, all while keeping chronometer or near-chronometer time. This may sound silly, but I'm selling it because it made me stop wearing all my other watches. [More pics](https://imgur.com/a/zBF1qls) I bought this from WatchBuys in February 2023, which was shortly after Sinn switched from a gold-colored rotor to the stainless one you see here. The watch is in good condition, but does show signs of wear and frequent strap changes. I've done my best to photograph the marks around the bezel as critically as possible. The Sinn black leather strap has been worn but is in good shape. Asking $1050 shipped CONUS. Venmo or PayPal G&S. Thanks for reading.

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.
