Hello everyone, Selling my Sinn 144 St S Anniversary II. It’s a limited edition (only 600 made) and a great mix of modern tech and classic design. It has a black scratch-resistant case, dehumidifying tech, sapphire crystal, and you can see the decorated movement through the back. The watch is long sold out and very few ever show up on the market. I really love this watch, but it’s a little too big for my wrist. I usually wear smaller watches (around 34mm), so I think someone else will enjoy this more than I do. **Condition:** Like new **Price:** $2,900 net, includes shipping and insurance in the U.S. (Retail was $3,450 and it's sold out. The only one I see listed is $4,800 on eBay.) I'm pricing this much below MSRP for a quick sale. **What’s included:** * Sinn rubber strap + aftermarket leather strap * Extra spring bars * Sinn leather box * Sinn spring bar tool * Booklet **Specs:** * 41mm case * Automatic movement (7750) * 200m water resistance * Sapphire crystal * Tachymeter and Pulsometer scales * Bright lume Payment by PayPal F&F preferred. G&S is fine if you have references (+4%). Let me know if you want more pics or have any questions. Thanks!

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.
