Embrace a legacy of maritime exploration with the Tudor Black Bay Bronze Ref. M79250BA. As a recipient of the “Petite Aiguille” prize at the Grand Prix d’Horlogerie de Genève, the Black Bay Bronze is celebrated for its daring use of materials and its deep roots in Tudor’s naval history.
The Magic of Aluminum-Bronze Unlike traditional gold or steel, the M79250BA is encased in a high-performance aluminum-bronze alloy. This material is chosen for its “living” quality; it oxidizes differently for every owner, meaning no two watches will ever look exactly alike after a few months of wear. To ensure comfort and hygiene, the caseback is crafted from bronze-colored PVD-treated stainless steel, preventing direct skin contact with the bronze while maintaining a seamless, monochromatic look.
Modern Mechanics: The MT5601 Beneath the domed sapphire crystal lies the Tudor Manufacture Calibre MT5601.This is the widest movement in Tudor’s catalog, specifically designed to fit the proportions of the 43mm case. It is a high-spec engine featuring a variable inertia balance and a silicon hairspring, making it highly resistant to magnetic interference. With a 70-hour power reserve, you can set the watch down on Friday evening and it will still be ticking accurately on Monday morning.
Heritage Design Cues The Ref. M79250BA is a masterclass in “Neo-Vintage” design. It draws inspiration from the 1950s Tudor Submariners with its oversized “Big Crown” (no crown guards) and the 1969 “Snowflake” hands favored by the French Navy (Marine Nationale). The slate-grey bezel and dial provide a more muted, versatile alternative to the original chocolate-brown version, making it an ideal companion for both rugged outdoor adventures and refined social settings.
