ATO Chronograph

ATO, founded by Léon Hatot, is best known for its pioneering electric clocks of the early 20th century, with only a very limited production of wristwatches.

This chronograph features a 33.5 mm stainless steel case with a gold crown, powered by a rare manual-winding Landeron 11 movement with Côtes de Genève finishing. The two-tone silver dial shows an even cream patina and applied Roman numerals.
