Ultimate Precision (UP)

With the new Optimum Curved UP collection, Jean Marcel is also introducing a new standard of quality and precision, focused on the precision of the movements. The internal specifications of this precision standard are stricter than the requirements of the official chronometer testing institute COSC.

Only watches with an average daily deviation in the range of 0 to +4 seconds are certified with the Ultimate Precision seal. In addition, the amplitude must be at least 270° and the beat error must not exceed 0.7ms. Every buyer receives a hand-signed certificate with his watch, documenting not only the average daily rate, but also the determined values for amplitude and beat error.
