Louis Vuitton unveils the Tambour Convergence Mirror Steel

At a glance

• Two numbered rotating discs display the hours and minutes through apertures; the numerals move gradually in a dragging display rather than jumping at the hour.
• The hardened steel case uses a patented treatment that raises surface hardness nearly sixfold. Mirror polishing contrasts with sandblasted lugs, and finishing takes up to three times as long as on the rose-gold model.
• It is fitted with an Arroyo Grey Saffiano calfskin strap and a hardened steel pin buckle.
