Timestamp: https://imgur.com/yD4BN8v Album: https://imgur.com/a/E6OLMV9 Sinn 142 D1, vintage, in incredible condition. $2,350 The case is almost completely free from blemishes. If you try hard enough, you can find tiny marks on the case in a few places, but they are hard to spot. The bracelet is in equally excellent condition. The crystal is spotless. There are enough links in the bracelet to accommodate a 7.5 inch wrist using the micro adjustments. I do not have extra links. The watch runs great and seems to be gaining about 12-15 seconds a day when worn. It has strong amplitude and I would wager that it was serviced not long ago, but I don't have records. Day wheel is in German. Functions work perfectly. The chronograph sweep minutes counter with orange airplane tip is a joy to behold. Functions reset exactly to 0. The movement is incredibly clean. I have included movement photos from the previous seller. Watch will come with bracelet as pictured. No box or papers. Price includes insured shipping anywhere, with payment via Zelle or bank wire. I've been buying and selling watches on the Internet for a quarter of a century with an impeccable reputation.

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.
