To develop this marvel of ingenuity, H. Moser & Cie. drew on the expertise of MHC Manufactures Hautes Complications SA, a specialist in minute repeaters. Together, the two manufactures created a brand-new design, showcasing the beauty of the complication by positioning the chimes and the hammers on the dial side. This involved overcoming many technical challenges. In particular, the chimes (which are placed on one level to preserve the finesse of the piece) had to be curved so as not to interfere with the flying tourbillon and to respect H. Moser & Cie.'s main focus to keep the design understated.
