A quick review of the basics: the watches have full ceramic cases (they’re marked with the chemical formula for the ceramic, zirconium dioxide, on the lugs and also on the dial – the latter very discreetly) and have screw-down case backs featuring the so-called Naiad locking system. The latter is a patented method of ensuring that the lettering (and, potentially, other decorative case back elements in the future) remain properly aligned with respect to the vertical and horizontal axes of the case. Water resistance is 600 m/2,000 ft, and there’s a GMT function as well, with independent setting of the hour hand in one hour increments. The case is 45.5 mm x 17.8 mm thick; however the watch wears lighter thanks to the ceramic case construction. As the watch is a Master Chronometer, it carries METAS certification for magnetic resistance to 15,000 gauss, and also COSC certification for accuracy. The movement is Omega co-axial caliber 8906, with a 60-hour power reserve, two barrels, and a silicon balance spring. Pricing is slightly higher than you might expect for a Seamaster, but there are also a lot of distinguishing technical features for which a premium can be justified, and which add up to a watch that really does stand apart from a lot of its competition.
