Sinn 140 St Black SZ-01 Caliber – Excellent Condition Pilot’s Chronograph

The Sinn 140 and 142 Series have been two of the most historically important watches since the company was founded.

Here’s some additional detail from Watchbuy’s website on this special watch:

Although the original Sinn 140 St has long since been retired, Sinn has now subjected the 140 Series to further refinement, technology and development, and introduces the 140 St series as offering the "very best of Sinn".

First, this watch features the Sinn SZ-01 movement in development for over seven years and first introduced on the Sinn EZM 10 TESTAF,

Many of Sinn's earlier 140 and 142 chronographs used the Lemania 5100 (and 1341) as the base caliber. This movement proved to be quite popular especially with the military who approved its use primarily based on its use of a large centrally mounted hand to show elapsed minutes.

Since that movement was discontinued, and other chronograph movements did not support these displays, Sinn announced many years ago that one of their goals was to create a number of in-house modifications to replicate the functions of the Lemania 5100.

Little did Sinn know the extent of the modifications that would be necessary, and that this project would extend over seven years.

Specifically, Sinn shows the elapsed minutes through a centrally mounted hand with a distinctive airplane pointer. The watch also features a centrally mounted elapsed second hand as well as an additional time second hand in the register at 9 which runs irrespective of the chronograph.

The result is an easy to read timing system with a large central hand that counts elapsed minutes on a 60 minute scale rather than 30, and a minute stopwatch scale which is visible around the entire circumference of the dial.

The Sinn 140 St Black also features an impressive array of Sinn technologies to ensure that it provides years of reliable use:

•Fully Tegimented PVD case
•Dehumidifying Technology system prevents fogging
•Nickel free case back
•Sapphire crystal with dual AR coating
•Rotating inner pilot's bezel activated through crown at 10
•Chronograph pushers and crown use Sinn's D3 case integration
•Matte black dial with electroplated counters
•Water resistant to 100 meters
•Weight without strap: 118 grams

Retails for $5160 plus the cost of the bracelet.

Asking $4,200 via bank wire, Zelle, venmo, or possibly PayPal Friends & Family with super strong references or if I know you. Price includes fully insured Fedex shipping in the Continental USA.

Please no trades.

Reputable seller with many positive reviews here, on Watchuseek (wooly88) and the Rolex Forum (wooly). Buy with confidence.

Let me know if you have any questions.

	Established:	1961
	Website:	http://www.sinn.de/de/
	Country of Origin:	Germany

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.
