Overview

The Tudor Black Bay Bronze ref. 79250BM stands as one of the most significant entries in the modern Black Bay lineage, bringing a 43 mm bronze case to a dive-watch silhouette already celebrated for its vintage-inspired character. Its warm brown dial harmonises naturally with the case material, creating a cohesive aesthetic that set it apart from the stainless-steel variants. Powered by Tudor's in-house Cal. MT5601, the reference combined manufacture-level credibility with the tactile, ever-changing appeal of bronze.

History

When Tudor introduced the Black Bay Bronze in 2016, it became one of the first references from a major Swiss manufacture to bring a solid bronze case to a production diver at this scale, helping to ignite broader industry interest in the material. The ref. 79250BM remained in production until approximately 2021, giving it a meaningful run during which its case developed the distinctive patina that collectors prize. Its release marked a turning point in the Black Bay collection's evolution from a vintage-homage line into a broader, material-diverse family. The reference is now regarded as a landmark piece in Tudor's modern catalogue.

Notable points

The 43 mm bronze case develops a unique, irreversible patina over time, meaning no two aged examples look identical — a quality that resonates strongly with collectors who value individuality.
The brown dial was chosen deliberately to complement the warm, golden-amber tones of the bronze case, giving the watch a unified, earthy palette rare among production divers of its era.
Cal. MT5601 is a manufacture movement developed by Tudor, offering a 70-hour power reserve, a silicon balance spring, and COSC-level chronometric performance.
The Black Bay Bronze ref. 79250BM is widely credited with accelerating the broader Swiss industry's adoption of bronze as a serious case material for production watches.
A domed, scratch-resistant sapphire crystal and a screw-down crown underline the reference's functional diver credentials beneath its distinctive aesthetic.
