The focal point of this design is the white mother-of-pearl dial, a natural surface set with 11 Top Wesselton VS-SI diamonds serving as hour markers (for a total of 0.044 carats). The display of hours, minutes, seconds, and the date is complemented by polished silver hands that glide across this chromatic backdrop.

The L157.3 caliber, a quartz movement powered by a RENATA 371 battery (SR920SW – 1.55V), manages the time and date functions. The mechanism includes a special E.O.L. (End-of-Life) indicator, designed to promptly signal the need to replace the battery before it runs out.

The round case is made entirely of stainless steel and features precise dimensions: a diameter of 34.00 mm, a thickness of 8.80 mm, and a width from lug to lug of 41.60 mm. Protected by a scratch-resistant sapphire crystal with a multi-layer anti-reflective coating on both sides, the case is water-resistant to 10 bar. The total weight of the watch is 90.0 g.

The stainless steel bracelet (with a 17-mm distance between the links) fastens to the wrist with a triple-security folding clasp equipped with a push-button release mechanism.
