Hi everyone, this is a catch-and-release for me. I'm selling a brand-new Sinn 556 mother of pearl watch on the fine-link bracelet. It's a gorgeous watch and looks great on my 6.5" wrist, but at 38.5mm, it wears just a tad larger than I prefer. (Others with 6.5" or smaller wrists probably won't mind, and may not even think it's large. Personally, I think I just prefer vintage sizing.) ETA: I should add that this watch has never been worn. I've taken it out of the box to hold against my wrist, but I haven't removed the protective plastic on the bracelet and haven't sized it. I purchased it at the start of January, so it's still under warranty, and the warranty card will be included. I'm asking $1500 OBO, shipping and insurance included. If I can get this sold today, I'll throw in [this grey nubuck strap](https://www.reddit.com/r/Watchexchange/comments/1k09u1w/wts_2_watch_straps_1_20mm_and_new_1_18mm_and_used/) from Watch Gecko for no extra cost. I ship from CONUS to CONUS. I accept Venmo or PayPal, and I can do PayPal Goods & Services for buyers with an established history on this sub. I'm a newer seller on this sub, so I'm happy to provide extra photos and videos if requested. Just let me know. ETA2: Here's a [video of the watch](https://imgur.com/a/7wRaXcv).

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.
