Quick TakeThe Master Collection Moonphase isn't just telling time; it's tracking the cosmos on your wrist. That deep blue dial, sparking with diamond stars, throws back to the night, and the moon phase? Pure class. The smooth sweep of the automatic movement is a total workhorse, a smooth 72 hour power reserve, packed in a perfectly sized 40mm steel case. It is a sharp, stellar piece, through and through.

DescriptionThe L2.909.4.97.0 timepiece features a circular stainless steel enclosure, measuring 40.00 mm in diameter and exhibiting an 11.10 mm profile. The distance between the lugs is 21mm, and the overall lug-to-lug measurement is 47mm. A transparent case back, constructed from sapphire crystal, allows observation of the inner mechanisms, complementing the scratch-resistant sapphire crystal protecting the dial. The assembly's total mass is 84.8 grams, achieving water resistance rated at 3 bar.

The watch is powered by the L899 caliber, a self-winding mechanical movement. It operates at a frequency of 25,200 vibrations per hour and is capable of a 72-hour power reserve. Time-telling is presented through polished, silvered hands upon a sunray blue dial, accented by 13 Top Wesselton VS-SI diamonds totaling 0.059 carats. Along with central hour, minute, and second functions, a moon phase indicator and date are positioned within a sub-dial at the 6 o'clock position. An alligator leather strap, presented in blue, fixes to the wrist, fastened using triple safety folding clasp.
