MATERIAL: Stainless Steel & 18ct Yellow Gold
Designed in collaboration with engineers Jakob Lüscher and Peter Döme of the Battelle Institute, Geneva, the OMEGA Constellation Megaquartz 2400 Marine Chronometer was the first quartz wristwatch to ever be awarded the status ‘Marine Chronometer’, granted such a title after 63 days of rigorous testing at the Astronomic and Chronometric Observatory of Neuchâtel where the mean variation rate of timekeeping was no more than 2/1000th of a second, or 0.73 seconds a year.
The OMEGA Marine Chronometer was additionally the first wristwatch equipped with a TSA (Time and Second Adjustment) that allowed fine independent adjustment of the hour and seconds hands and, with a resonator vibrating at a rate of 2,359,296 times a second. Both provided unmatched precision within an imposing case moulded from a thick block of stainless steel, upon which a slice of 18ct yellow gold was screwed down at its four corners to frame the dial. Additionally, inspired by early Marine Chronometers, each movement number was set into the side of the case in homage to the skill of early horological pioneers.
