Hey [r/Watchexchange](https://www.reddit.com/r/Watchexchange/), Letting go of my **Sinn 556A** – one of the cleanest and most legible daily watches out there.

Crystal and case are clean. * **Set**: • Full set (box + papers, 2023) • Original Sinn black leather strap • Original Sinn H-link bracelet (feels like two different watches with strap/bracelet swap) ✨ **Why this piece stands out** * ✅ Beloved Sinn tool watch with timeless 556A dial * ✅ Comes with both OEM leather strap + H-link bracelet * ✅ Recent 2023 full set * ✅ Excellent condition – ready to wear 💲 **Price: $1300 shipped (CONUS)** **Payment**: Zelle or PayPal F&F (G&S +3% if buyer prefers) **Reasonable offers only** **No trades** **If you have any questions, please do not hesitate and send me a message!

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.
