Hey Everyone, Up for sale is a solid Sinn 556i. Overall condition is good, as seen in the photos. Crystal is clean and scratch free allowing it to showcase the deep inky black dial. There are some marks on the lugs and bezel. This 556i was purchased from Watchbuys, an authorized dealer, on January 2024, so there is plenty of warranty left. Package includes inner and outer boxes, warranty card, adjustment tool, and aftermarket tropic strap. If you would like a bracelet option, I have a Ginault one that we can discuss. Asking for $995 (Zelle) plus cost of your preferred method of insured shipping.

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.
