Through extensive research, I have determined that the Sinn 142 was not the first automatic chronograph in space. That distinction now belongs to the Seiko 6139-6002, which flew with Col. William Pogue aboard Skylab4 for approximately 3 months. Please click here for more information. This site will remain up as I still believe the Sinn 142 to be a fantastic watch, proven through it's use on many missions in space.

The Sinn model 142 holds a unique position in the history of manned flight. In 1985, Reinhard Furrer wore a Sinn 142 on a D1 mission (STS-61, Challenger), thereby giving it the distinction of being the first automatic chronograph worn in space. Check out 142 Info to understand why this watch was personally chosen for use by several astronauts and the German special forces unit GSG9.

I believe the Sinn 142 is an important watch that needs to be documented. To that end, I've gathered as much information as I can in an attempt to educate the public and <hopefully> begin to fill in some holes concerning the history of this watch.

Special thanks to Inh. Helmut Sinn for providing me with information and pictures related to the 142

Company Background

Sinn was formed in 1961 by the legendary pilot and flight instructor Helmut Sinn.  They began manufacturing flight watches based on his extensive aviation experience, this was primarily based on Mr. Sinn's dissatisfaction with the watches that were available for pilot and navigational purposes at that time.  His own designs incorporated the features and functionality that he felt more fit for purpose as an instrument watch.  This is a design philosophy that has transcended the company's culture right through to the present day.  Sinn is now the world's most eminent manufacturer of high quality, precision, functional and purposeful instrument watches.  From the beginning, their emphasis was on creating special purpose instruments that performed under extremely adverse operating conditions such as high speed, high and low pressures and altitudes, intense heat or pressure, extreme cold, high magnetic interference, and submergence in liquids.  Sinn are becoming increasingly known for their instrument watches, and are today a force to be reckoned with as they lead the way in instrument watch design.
