With the Streamliner Concept Minute Repeater Tourbillon Blue Enamel, H. Moser & Cie. presents one of the most traditional and romantic watch complications and combines it with a magnificent flying tourbillon performing a spinning waltz. Drawing attention to the minute repeater mechanism, it has taken the bold decision to position the two shaped gongs and the hammers on the dial side, in a brand-new design. This involved overcoming many technical challenges. The gongs, in particular, which are on a single level in order to preserve the ergonomics of the piece, had to be curved so as not to encroach on the flying tourbillon and to respect the purity of design for which H. Moser & Cie. constantly strives, with the balanced proportions, fluid shapes and high-flying finishes characteristic of the Streamliner line.
