Every movement that ETA has developed since 1793 is guided by precision, reliability and performance. Now the Swiss movement-maker has raised its standards of quality even higher to propose a record level of precision: +/- 10 seconds per year or 0.027 second per day. This unprecedented accuracy is down to PreciDrive exclusive technology. Integrated into a collection of eleven new quartz movements, this new development has no trouble meeting COSC criteria to obtain “Chronometer” certification. This ultimate degree of precision comes in five calibre sizes from 7¾´´´ to 13¼´´´ with or without date. The height of the calibres in the FOX family remains the same to offer interchangeable movements with various cases.
