Details & Specifications
Description:
Reference 3623.50.01 is cast entirely in 18ct rose gold, its 39mm barrel-shaped case carrying gently curved lugs and a flat bezel with an engraved tachymeter scale to 500 units per hour. The black dial holds a matte depth beneath the sapphire crystal, with rose gold-toned hour markers standing out warm against the darker background. The layout runs three compax sub-registers for the chronograph, alongside twin apertures for the day and month and a fourth hand tracking the date — a genuinely busy dial, but one that stays legible thanks to the clear separation between registers. Fluted chronograph pushers and a screw-down crown flank the case, both signed and finished in matching rose gold.
Inside is Omega's automatic Caliber 1151, a chronograph movement built on a modified Lemania base, delivering approximately 44 hours of power reserve alongside its day, date, and month complications. An alligator leather strap closes on an 18ct rose gold tang buckle, keeping the wrist presence entirely in precious metal without the added weight of a full gold bracelet. Water resistance reaches 30 meters, adequate for daily wear though not intended for swimming or submersion.
Year: 1999. Presented as a full set.
