The Tudor Black Bay Chrono reference 79360 represents the 2021 evolution of the brand's in-house chronograph, introducing a cleaner panda-style dial layout and revised bracelet architecture to the line first launched at Baselworld 2017. This blue-dial variant features a bi-compax configuration with silver counters at three and nine o'clock against a satin-finished blue base, the contrast lending the watch a sportier presence than its predecessor's monochrome execution. The 41mm stainless steel case retains the diver-style screw-down crown and 200-meter water resistance that connect the Chrono to the wider Black Bay family, paired with a fixed steel tachymeter bezel carrying a blue anodized aluminum insert with silver markings. Tudor's signature snowflake hands and applied luminous markers complete the dial, with date display at six o'clock and a 45-minute counter at three. Powered by the Tudor Caliber MT5813, an integrated chronograph movement with vertical clutch and column-wheel control, COSC-certified at 28,800 vibrations per hour with a 70-hour power reserve and silicon balance spring across 41 jewels. Fitted on a 5-link stainless steel bracelet with T-fit micro-adjustment clasp. 2024 production, pre-owned with full Tudor box and papers.
