Hi, Forget the common automatic versions—this is the **elusive hand-wound Sinn 103** from the mid-1990s, a **serious collector’s piece** that rarely surfaces. Bold Arabic numerals with **vintage tritium lume**, a rugged bi-directional countdown bezel, and a rock-solid day-date complication—this watch was built to perform, and it still does **flawlessly**. I’ve loved owning this beauty, though it hasn’t gotten the wrist time it deserves. Parting with it hurts, but here’s your chance to own a **true Sinn rarity** from 1995. **Condition:** in good cosmetic condition, the watch has it serviced in July, all functions working probably. **Including:** Vintage Sinn H link bracelet for 7.087 inches wrist, a green nato strap. No boxes, no papers. --- **[Pics | Timestamp](https://www.flickr.com/photos/61327256@N05)** Check it out ?! --- **Price: $1500 + shipping** (PP F&F or G&S +4.6%) **Shipping:** FedEx/DHL worldwide **Feedback:** 121+ flawless transactions (ask away!) **DM me to claim this beauty—or follow @Watchtique for more rare finds!**

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.
