tak je to vic nez "jen", viz stranky Omega: What is the difference between a chronograph and a chronometer?
A chronograph is a watch with hands that display hours, minutes and seconds, together with a mechanism for measuring elapsed time by means of a central chronograph hand, which records seconds, and 30-minute and 12-hour totalisers. A chronometer is a watch that has obtained an official rate certificate from the COSC (Official Swiss Chronometer Testing Institute) after having passed precision tests in different positions and at different temperatures, as well as water-resistance tests. These tests are conducted over a 15-day period.
