Hola a todos, acabo de decidir adquirir un Carrera chrono, calibre 7750 y mi gran duda es saber en que se diferencian los calibre,,,es por la precision? numero de componentes?, materiales?,,,ayuda!!!!
Gracias!!!
Hola.
Bueno, supongo que te refieres a si, por ejemplo, el calibre 17, es mejor que el 16, o mejor que el 8...etc.
La respuesta es no. La denominación de Calibre "X", entiendo que es simplemente comercial. Lo que sí nos indica el número de Calibre es la maquinaria que monta. Te dejo un enlace en el que puedes verlas:

En este otro hilo, quizás puedas solventar alguna que otra duda:

Respecto a la ETA 7750 (Calibre 16) es una gran máquina. Muy probada y fiable, con 40 años de mejoras a sus espaldas. Uno de los movimientos cronógrafo más duros y usados actualmente... Te dejo algo de información...

Algo de información a primera vista:
Valjoux 7750
ETA/Valjoux 7750.
The Valjoux 7750 a/k/a ETA 7750 is a widely used chronograph (stop watch) movement operated by cams integrated into the movement. The traditional mechanism used in the chronograph is known as the Column Wheel. With the advent of the Valjoux 7750, the column wheel was abandoned for a three plane cam system. The three plane cam system is properly known as the Coulisse Levier mechanism. The system and movement were developed by Edmond Capt in 1970, as a fully integrated self-winding mechanism with quick-set day/date based on the Valjoux 7733.
The movement is an automatic winding, twenty-five (25) jewel movement, which can be fitted with a variety of features including the triple date (day, date, month and moon phase) or a variety of two and three register models with totalizers or counters for minutes, seconds and hours. It is available in three executions or grades: Elaborated, Top and Chronometer. The key components which differ at the line of demarcation between Elaborated and Top are the pallet stones, balance wheel & hairspring and the regulator mechanism. To illustrate the differences in accuracy garnered by the successive grades, consider the following specifications: the Elaborated grade is adjusted in three positions with an average rate of +/-5 seconds/day with a maximum daily variation of +/-15 seconds/day; while the Top grade is adjusted in five positions with an average rate of +/-4 seconds/day with a maximum daily variation of +/-10 seconds/day. The Chronometer grade must meet strict standards prescribed by the [COSC]: an average rate of -4/+6 with a maximum daily variation of +/-5 seconds/day.
Un saludo.
