The name of Hanhart, more than any other, has long been synonymous with precision timekeeping. With its own innovative developments, the Swiss-German brand was a pioneer in the manufacture of stopwatches and wrist chronographs. Ever since the company was first established, all of Hanhart's timepieces have been geared towards a few simple principles: maximum precision and reliability, perfect readability, simple and secure operation, and the greatest possible robustness. And we are still conforming to these standards today in the development of our stopwatches and chronographs.
This makes them ideal accessories for use in the air, on the land on the sea. Our brand slogan "Mastering the Elements" is an unequivocal obligation for us.
Thanks to cutting-edge knowledge and skills,
the long-standing tradition and expertise of its own manufactory, which has its origins in the watch business established by Johann A. Hanhart in Diessenhofen in 1882, and the first-class functionality of all products, Hanhart is today a worldwide market leader and the most important producer of precision timepieces.

Yup. And there are a couple models using the monopusher valjoux movement, although I can't remember the caliber #.
