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.
The dial of the BONZER electric is deliberately simplified and assembled with understated and elegant indices.
A subtle railway track is printed outside the hour markers. The steel date window at 3 o'clock displays retro-style numerals in white on a black background, and in green on the 3rd of each month. The day of the month can be displayed in French or English, according to your preference.
The M logo is a finely cut appliqué.
The hands are shaped like tuning forks to frame an optimal reading.
Luminova is applied below each hour marker as well as on the face of the hands.
The glasses of the BONZER Electric are constructed of colored aluminum.
They rotate on "120 clicks" for precise time measurement.
The interlaced lines of March LA.B are chiseled with very high precision around the circumference of the edge.
The overall effect is harmonious and completes the signature construction of the case.
