This has been my beater watch but since I picked up my new Promaster I don't use it anymore.

It is 1000 m water resistant and has a fully tegimented case and also a tegimented clasp on the Sinn strap. It is cut to fit wrists up to 7'. The strap and clasp alone is $250.

It has some improvement, and an issue which is why I'm letting it go cheap. The lume was initially disappointing. I've added a layer of C3 X1 to the hands and cardinal indicies. I've also adjusted it in 5 positions and pressure tested it.

It has a scratch on the sapphire crystal. Not sure how that happened.

Shipping is included in the price and will be via EMS Express Courier.

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.
