Overview

The Tudor Black Bay Chrono reference 79350 marked a significant milestone for the brand as its first chronograph to house an in-house movement. Introduced in 2018, the 41 mm stainless steel case carries the Black Bay family's characteristic vintage aesthetic, here applied to a sport chronograph format. The black dial and column-wheel-controlled Cal. MT5813 placed the reference firmly in the upper tier of the accessible Swiss chronograph segment.

History

Tudor introduced the Black Bay Chrono line at Baselworld 2017, with the reference 79350 entering production in 2018 as the first-generation expression of that debut. The Cal. MT5813 was developed in collaboration with Breitling, sharing its architecture with the Breitling Calibre 01, and represented Tudor's first foray into manufacture chronograph movements. The reference remained in production through 2021, after which it was succeeded by updated variants within the Black Bay Chrono family. Its relatively focused production window has made it a notable early chapter in Tudor's modern manufacture era.

Notable points
