Distinguished by its precision and reliability, the Swiss quartz RONDA 517 caliber proves to be the best choice for many luxury watch brands due to its extremely high-quality performance.
This Swiss movement is equipped with a quartz oscillator that uses electrical vibrations to maintain remarkably high time precision. It also features a temperature regulation system, which adjusts the movement's frequency according to thermal fluctuations, thus guaranteeing constant precision 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 2 weeks before the end of the battery's life, an indicator called EOL causes the second hand to jump every 4 seconds to signal the need for a battery change.
The AM89 Électrique's dial is deliberately simplified and assembled from understated and elegant indices.
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. A discreet printed railway track marks the inside of the indices.
The M logo is a finely cut appliqué.
The hands are slender to allow the overall design to breathe.
All March LA.B watch cases meet scrupulously respected construction criteria. Invariably polished and brushed, they capture ambient light to bring your watch to life.
The AM89 is a handsome 38mm round case, 13.2mm thick, with angular, streamlined lugs that reveal a slight flat surface around the immaculate polished bezel.
The contrast of the lines makes it a modern watch, slightly vintage yet contemporary at the same time.
The slightly raised mineral glass is angular to reassert the character of this more classic watch.
The round crown, positioned at 4 o'clock, has been simplified and reduced for greater elegance and simplicity.
