Distinguished by its precision and reliability, the Swiss quartz caliber RONDA 517 proves to be the best choice for many luxury watch brands due to its very high-quality performance.
This Swiss movement is equipped with a quartz oscillator that uses electrical vibrations to maintain remarkably high timekeeping accuracy. It also features a temperature regulation system, which adjusts the movement's frequency according to temperature fluctuations, thus ensuring consistent accuracy regardless of ambient conditions.
In addition to its precision, it is also designed to be extremely reliable and durable. It features a long-life power supply system that allows for a battery life of up to 45 months. Approximately two weeks before the battery is depleted, an indicator called EOL (End of Life) causes the seconds hand to jump every four seconds to signal the need for a battery change.
