TUDOR Black Bay Chrono S&G Watch M79363N-0001

The TUDOR Black Bay Chrono S&G (Ref. M79363N-0001) combines TUDOR’s diving heritage with legitimate chronograph capability in a steel and gold package that elevates the standard Black Bay formula. The solid yellow gold pushers and select bracelet links provide genuine precious metal content rather than simple gold plating, whilst the matt black aluminium bezel insert maintains the tool watch aesthetic.

At 41mm with 14.4mm thickness, this strikes the right balance between presence and wearability for a chronograph. The distinctive “Snowflake” hands maintain TUDOR’s diving watch DNA while the black domed dial and circular-grained sub-counters create visual depth. The 45-minute counter reflects first-generation TUDOR chronograph heritage from 1970.

The Manufacture Calibre MT5813 delivers COSC certification with 70-hour power reserve and proper column wheel/vertical clutch construction. This eliminates the chronograph hand flutter common in cheaper mechanisms and provides the smooth operation expected from a serious timing instrument. The 200m water resistance maintains diving capability despite the chronograph complication.

The steel and gold bracelet uses solid yellow gold for the first centre links at 6 and 12 o’clock positions, with the remaining centre links gold-capped. This creates visual consistency whilst managing cost compared to fully solid gold construction.

This Black Bay Chrono S&G suits buyers who want TUDOR’s diving heritage with precious metal refinement and legitimate chronograph functionality. The solid gold elements and Manufacture movement elevate it beyond basic sport chronographs, whilst the diving watch DNA and 200m water resistance maintain versatility. It bridges the gap between tool watch functionality and luxury finishing without compromising either aspect.
