It wouldn’t be a two-tone watch without a healthy application of gold accents. On the right side of the 41mm case, you’ll find two screw-down pushers and a crown that are made from yellow gold. The fixed bezel is also gold, which is really only visible at an angle. A matte black anodized aluminum bezel runs around the outside of the dial, decorated with a gold tachymeter scale. A bunch of dial features are rendered in gold, including the two textured subdials, chapter ring scale, dial text, hands, and applied indices. The riveted bracelet and end links all have a gold center link with brushed finishing. There are two small red accents on the watch which I think really help break up the silver/gold/black theme. On the running seconds hand, there’s a red tip that nicely complements the single line of red text at the 6 o’clock position. It’s worth noting that the bezel, pushers and end-links feature solid gold, while the crown and main bracelet links are capped gold (which is thicker than plating).
Inside the S&G Chrono is Tudor’s in-house MT5813 automatic chronograph movement. In addition to being chronometer certified, the MT5813 has traditional mechanical chronograph features including a column wheel and vertical clutch. One of the most appealing aspects of the movement is the impressive 70-hour power reserve. The movement powers two sub-dials at 3 and 9 o’clock — a 45-minute counter at 3 and running seconds at 9. Instead of another chrono register at 6, there’s a chamfered rectangular date window aperture.
