For sale is a Sinn 556A in leather strap. This is a newer 2020 model with the Sellita SW200 movement. The leather strap is usable, but is due for a replacement. My personal recommendation is to get an aftermarket Sinn President bracelet from Uncle Straps for $99. It comes with solid end links, milled clasp and a taper of 20mm to 16mm; way nicer than the $330 H-link strap with the crappy clasp. If you would like to stick with a leather strap, get a higher quality one and swap over the Sinn buckle; otherwise an oem Sinn strap will cost about $80. There are some wear marks on the bezel, but sapphire crystal is spotless and case and lugs have no deep scratches. I've been using mostly my Bond nato strap with it the last year or so, so will include the nato strap and curved spring bars. Accuracy averages about +3-5spd. Comes complete with all box and paper.

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.
