Up for sale is my Sinn 556i RS. Great condition with minor desk dive type wear. It has been worn in rotation but mainly in office type settings. Originally purchased from WatchBuys in 2022. I have included pictures both in natural lighting and harsh office lighting. $1200 via PayPal F&F includes expedited and insured CONUS shipping. Full kit. Currently sized not too tight for my \~7.25” wrist and there are 2 extra links. I prefer to deal with people with transaction history. I have lots of transactions here and elsewhere with nothing but positive feedback. I \**might\** be interested in trading down. A PRX in gold or light blue would be of interest. Or maybe a solar Seiko diver. Thanks for looking!

Thanks Herby81. Great Seller.

Had a great transaction with Herby81. I didn't have much feedback on this particular forum but after some prompt communication back and forth he was willing to accept the payment through Paypal GS, even though the watch was fairly expensive.

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.
