Tudor continues to make ever-more assured strides in building eminent value-proposition watches. At Baselworld 2018 the brand unveiled its first dual time zone watch, the Black Bay GMT. And it’s happening just as its bigger brother, Rolex, finally rolls out a GMT-Master II “Pepsi” in stainless steel.

Measuring 41mm in diameter, the same as the standard Bay Bay diver, the Black Bay GMT is stainless steel with a red and blue GMT bezel insert that’s made of anodised aluminium and features an appealing Art Deco style font.

Notably the bezel is bidirectional and has 48 notches, or “clicks” when rotated, which means it can track time zones offset by 30 minutes, going beyond the common 24 time zones.

While the overall style is identical to the Black Bay diver, several minor tweaks were made, including shrinking the size of the hour indices and hands, to avoid leaving the dial over crowded.

It’s equipped with a new in-house COSC-certified movement, the MT5652, featuring a variable inertia balance wheel and silicon hairspring.

The MT5652 has a 70-hour power reserve and a fully integrated GMT function, indicated with a red “snowflake” hand.

And though the movement is thicker than its related time-only calibre, the Black Bay GMT has the same case height, just 14.6mm, as the standard Black Bay thanks to some clever design tweaks.

Another change is the the crown tube, which has satin brushed finish instead of the coloured, PVD-coated tube found on other Black Bay models.
