Scratches are the tax every mirror-polished steel watch pays, and the Louis Vuitton Tambour Convergence Mirror Steel is built to avoid it, according to the maison. The new reference, W9ST11, wraps a 37mm case in hardened stainless steel and polishes it to a full mirror finish. Louis Vuitton says a patented treatment raises the surface hardness of that steel by nearly six times.

The watch is the fourth model in a line that began in January 2025. The Tambour Convergence debuted at LVMH Watch Week that year as a guichet watch, according to The Hour Markers, meaning it shows the time through a small window instead of hands. Sharp Magazine traces the format to the 1920s. As reported by Wallpaper*, it was the first guichet watch created fully at La Fabrique du Temps Louis Vuitton, and the first three versions came in rose gold, diamond-set platinum and guilloché rose gold. Steel is the first departure from precious metal.
The Louis Vuitton Tambour Convergence Mirror Steel case, and the polish behind it
The case, lugs and crown all get the high-polish finish, according to the release. Louis Vuitton rates the surface at 1,130 Vickers, which it describes as only slightly below high-tech ceramic. The brand also says the steel is a high-purity grade used in medical implants, and that the combination of purity and hardening lets the surface take a deeper polish and keep it longer than most polished metal watches.
The claim that matters most to anyone who has owned a polished steel watch is the simplest one. Louis Vuitton says minor scratches that would stand out on ordinary steel blend into this mirror finish. That is the company's statement, and it has not been tested independently.
The finishing is slow by the brand's own account. Each case takes up to three times as long to complete as the rose gold model, and the artisans doing it must learn how the hardened steel responds under polishing tools. Matthieu Hegi, artistic director of La Fabrique du Temps Louis Vuitton, told Wallpaper* the watch is "a statement piece that showcases the audacity and innovation of Louis Vuitton watchmaking."

The design is unchanged. Two rotating discs, set behind an arched aperture with scalloped edges, carry the hours and minutes. Louis Vuitton says the window shape recalls interior architecture at the Family Home in Asnières.
In-house caliber and price: what sits beneath the steel
Inside is the self-winding caliber LFT MA01.01, which the brand calls the first time-only automatic manufacture movement conceived and produced entirely by La Fabrique du Temps. The specifications listed by Louis Vuitton include a 4Hz beat rate (28,800 vibrations per hour), a 45-hour power reserve, 201 components and an 18-carat pink gold oscillating weight. A sapphire caseback exposes the movement. Water resistance is 30 meters.

The strap is grey Saffiano calf leather with a beige calf lining, closed by a hardened steel pin buckle engraved with the Louis Vuitton signature. The release gives no price. WatchTime reported a U.S. price of $25,200, while Monochrome Watches listed EUR 26,000 against EUR 38,000 for the rose gold model. Both figures come from the outlets, not from the release. The reference page on the official Louis Vuitton site lists the watch as W9ST11.
Steel moves the Tambour Convergence out of the precious metal tier it has occupied since launch, and several outlets describe it as part of the permanent collection. WatchTime called it a materials project rather than an entry-level steel model. Whether collectors read a $25,000 steel watch as an on-ramp or as the point of the exercise is a question sales will answer before any press statement can.
