Founded in 1926 by Hans Wilsdorf in Geneva, Tudor has grown into a genuine manufacture in its own right, with a strong identity and an increasingly devoted collector following. The Black Bay 58 is the collection's most refined and wearable expression — and the Bronze edition brings something genuinely new to the line: a material that ages and develops character with every year of wear, exclusively available through Tudor boutiques.

The Tudor Black Bay 58 Bronze, reference 79012M, is a beautifully distinctive 39 mm watch crafted entirely from a high-performance aluminium bronze alloy used in naval engineering — a material that develops a unique and subtle patina over time, making every example a little different from the next. The gradient matte brown-bronze domed dial, shading concentrically from the edge toward the centre, is matched by a unidirectional bronze bezel in the same warm tone, with gold-coloured applied Arabic numerals at 3, 6 and 9 o'clock filled with Super-LumiNova. This is the first Black Bay 58 to feature an open sapphire caseback, revealing the movement in a way no other reference in the line offers. At its heart beats the in-house COSC-certified Calibre MT5400, with a silicon balance spring and 70-hour power reserve. A domed sapphire crystal protects the dial. Water resistance is rated at 200 metres. The watch is fitted on a solid bronze three-link bracelet with the T-fit micro-adjustment clasp without the additional Nato strap. 

This Black Bay 58 Bronze is in near mint condition and comes as a full set.
