Asking for $2250 OBO via PayPal Goods & Services shipped to CONUS only. No trade offers at this time please. Information: Selling a Sinn 356 Sa chronograph watch purchased from the Sinn factory in Frankfurt on November 7th, 2023. This watch comes with a sapphire crystal, solid caseback, and is in a matte finish. Sinn's manufacturer's warranty is 2 years so the watch is still under warranty until November 7th, 2025. Days of the week are in German. Condition: There was a warranty issue in which the watch was running 2-3 hours fast so overhaul service was performed in February 2025 by Watchbuys which included: new mainspring, new reversing wheel, new escape, new palletfork, new caseback gasket, case cleaning, water resistance testing, and a new dial. Some minor scratches and signs of wear. I'm selling because luxury watches just aren't for me and I'm also going on vacation soon. I'm more than happy to hop on a Zoom call to show and discuss the watch.

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.
