Quick TakeLike a slice of the midnight sky, the blue mother-of-pearl dial shifts with every turn of the wrist. Twelve brilliant diamond indexes glitter against the iridescent depths, their light traced by slender silvered hands. This isn't a watch you have to think about; its slim 4.50 mm case and featherlight 17.7 g weight make it a pure expression of style. The reliable L420 quartz heart means it's always ready. Paired with a deep blue alligator strap, it is effortless elegance for any occasion.

DescriptionThe timepiece is constructed from stainless steel, fabricated into a round case shape with a diameter of 29.00 mm and an overall thickness of 4.50 mm. The lug-to-lug dimension is 33.20 mm, and the interhorn width measures 16 mm. Protection for the dial is provided by a scratch-resistant sapphire crystal. The complete assembly has a total mass of 17.7 g and is certified for water resistance up to 3 bar. This model is engineered for functional time-telling, displaying only hours and minutes via silvered polished hands.

Powering the mechanism is the L420 quartz caliber, which operates on a RENATA 346 battery. The dial is composed of blue mother-of-pearl, upon which the hour markers are designated by 12 Top Wesselton VS-SI diamonds, amounting to a total carat weight of 0.081. The watch is secured to the wrist by a blue alligator strap, which is fastened with a standard stainless steel buckle.
