Tudor 79730 Heritage Black Bay SS Black Dial

The Tudor Heritage Black Bay Steel ref. 79730, introduced circa 2017, marks a pivotal evolution in the storied Black Bay lineage by integrating a date function for the first time and replacing the traditional aluminum bezel with a brushed stainless steel insert. Powered by Tudor’s in‑house, COSC‑certified Calibre MT5612, this automatic movement delivers a robust 70‑hour power reserve and operates at 4 Hz, underscoring its technical prowess and modern reliability. The 41 mm stainless steel case, measuring approximately 15 mm thick and spanning about 50 mm lug‑to‑lug, balances vintage dive watch proportions with contemporary wearability. Water‑resistant to 200 meters, it features a domed sapphire crystal and the signature snowflake hands, reinforcing its heritage DNA. The satin‑brushed steel bezel with engraved 60‑minute scale and red‑tipped luminous triangle adds tool‑watch functionality and visual depth. Offered on either a riveted steel bracelet or aged leather strap (with additional fabric option), the watch appeals to collectors seeking both versatility and historical resonance. As the first all‑steel, date‑equipped Black Bay, the 79730 holds a unique place in Tudor’s modern dive watch narrative, combining utilitarian design with in‑house movement excellence. Excellent condition with Tudor box and papers dated 2019.
