Do you like Tudor? Do you like fully bronze watches? Then we have news for you! The newly announced Tudor Black Bay Fifty-Eight Bronze is a boutique edition, which is not limited to a specific number of pieces but only to the locations where it can be found and purchased, which is about 50 Tudor boutiques worldwide.
The Tudor Black Bay Fifty-Eight Bronze model, presented in a very popular 39mm case with a thickness of 11.9mm and a lug-to-lug length of 48mm, is now complemented by a bronze bracelet to further emphasize the trendy bronze watch theme. Tudor calls this color palette a "rich brown-bronze tone," and the deep brown dial and bezel complement the fully bronze look.
The material itself is described as a "living metal, a high-performance aluminum bronze alloy used in naval engineering for underwater parts that must exhibit a high level of corrosion resistance, such as propellers." Bronze watch enthusiasts know well that this metal develops a fine and unique patina over time (unless you try to accelerate this process with saltwater and ammonia, in which case it happens very quickly depending on the specific alloy).
Tudor cases and bracelets generally have excellent finishing, especially in the Black Bay and Pelagos collections, and this makes the endeavor even more intriguing. Watching patina form on a block of metal is certainly fascinating, but there is an element bordering on masochism in seeing such neatly polished and precisely machined surfaces become patinated in places. For some, it's heresy; for others, it's a new level of enjoyment in watch ownership. Tudor claims to have given the Black Bay Bronze a "fully satin finish [to] ensure a homogeneous patina development."
How Tudor Bronze Watches Are Made
The aluminum bronze alloy used by Tudor is produced in the form of bars, which are then cut into bullets (small cylinders of material) several centimeters long. The bullets are then heated to such a high temperature that they glow orange and are then stamped individually with multi-ton pressure. Thanks to this single operation, once the raw material cylinder exits the furnace, it instantly takes on the rough shape of the middle watch case.
After this, about 40 more steps are needed to obtain a bronze case ready for assembly. Successive machining processes create the final shape and manufacture the functional parts of the case, such as cutting threads or drilling holes, and surface finishing is performed both on automatic machines and manually. Since bronze is a material whose appearance quickly changes depending on the environment, all these manufacturing operations, as well as the assembly and final testing of the Black Bay Fifty-Eight Bronze model, are carried out with particular care, in gloves, and following a specific technological process, especially during water resistance tests. Between tests, each watch is completely dried to maintain its new, unpatinated appearance.
Tudor adds a braided brown-bronze fabric strap with a bronze buckle to the set - probably anticipating that, at least for some, the fully bronze bracelet and its weight may be too heavy for prolonged wear. Nevertheless, the T-Fit adjustment system built into the bronze bracelet clasp is a welcome addition: It allows for instant, tool-free length adjustment of the bracelet in five different positions within an adjustment window totaling 8 millimeters. Five steps of 8mm are practically all you need for perfect length adjustment of a metal bracelet throughout the day (and also the season), as our wrists tend to expand and contract due to various factors, including heat, humidity, physical activity, etc. Such a micro-adjustment system should be part of every luxury watch's metal bracelet, without question.
The Tudor Black Bay Fifty-Eight Bronze is equipped with the Tudor MT5400 manufacture caliber, offering a solid 70-hour power reserve combined with chronometer precision certified by COSC. Moreover, Tudor itself exceeds this by insisting on a deviation of -2 to +4 seconds for each unit after full assembly (while COSC only checks uncased movements). The non-magnetic silicon balance spring, variable inertia balance, and micro-adjustment screws allow this automatic movement to maintain the 200-meter water resistance of the 39mm bronze case.
The Tudor Black Bay Fifty-Eight Bronze watch with a bracelet costs $4,525 and is available exclusively at Tudor boutiques. Considering the advanced in-house movement, the rather rare bronze finish, the quality of execution, and the five-year warranty, the Tudor Black Bay Fifty-Eight Bronze is a powerful, albeit niche, offering.
