The deluge of cool shit from Tudor continues. This time it’s everybody’s favorite Black Bay dive watch, but in black ceramic. It’s stealthy. It’s sexy. And…it’s METAS-certified.
This is the first METAS-Certified Tudor watch
Wait, you might be asking yourself, what does that even mean? Sit back and let me tell you. See, METAS (the Federal Institute of Metrology) administers a Chronometer certification test for accuracy in watchmaking. To pass, a watch must maintain certain levels of precision, resistance to magnetism, waterproofness, and power reserve, including accuracy to within a five-second range per day.

For comparative purposes (or “comparative porpoises,” which is what I almost typed, and which is, I guess, two dolphins trying to one-up one another), the COSC (Swiss Official Chronometer Testing Institute) accuracy standard for Chronometers that we all know and love to quote is -4 to +6 seconds per day carried out on a single movement. Tudor’s internal standard for its manufacture calibers is even better, at -2 to +4 seconds per day, and its movements are Chronometer-certified anyway.
So what does this effectively mean? Well, as the kids might have said when I was a kid, the new Tudor Black Bay ceramic is, like, hella accurate and robust.
The watch can resist magnetic field of up to 15,000 gauss (which is really just a ton of gauss) and its waterproofing standard conforms to ISO’s standards. It’s been tested in six positions at two temperatures, and at two different levels of power reserve. The automatic, in-house Tudor cal. MT5602-1U — executed in all-black with an openworked rotor — has a 70-hour power reserve, and the case is water resistant to 200m.
