Introducing: The Tudor Black Bay Chrono 39 "Bumblebee"
What We Know There's a new Tudor chronograph in town, and guess what, it's smaller. After kicking off the format in 41mm back in 2017, Tudor has now downsized the brand's dive/drive chronograph design to a new 39mm case width. The new Tudor Black Bay Chrono 39 "Bumblebee" sports a bright and vivid yellow dial with black counters, giving the new reference (79310N) a link to the preceding Pink and Flamingo Blue versions of the Black Bay Chronograph. We can get to the dial in a moment, but for a smaller take on any Tudor, let's start with millimeters. The new Black Bay Chronograph 39 measures 39mm wide, 13.1mm thick, and 47mm lug-to-lug. Compare that to 41 x 14.4 x 49.9 of the current 41mm model, be it white, black, blue, black & gold, pink, or flamingo. Water resistance remains at 200m with screw-down crowns for the chronograph controls, and that bright yellow dial is framed by a fixed tachymeter scale rendered in black aluminum. On to the dial, which is colored a bright and punchy yellow as a nod to the brand's "Tiger" chronographs of the 1990s. The markers and hands have black surrounds, and the water resistance is shown in red (as it is on the Black Bay Chrono 39's larger counterparts). Tudor also notes that the snowflake hands have been redesigned to aid in chronograph legibility. While I have yet to measure more accurately, if you compare the reach of the hour hand toward the 60 marker on the running seconds subdial, it appears shorter than in the 41mm models. Tic...
