A Franck Muller ref. 1900 S6 in 18ct yellow gold, case number 03, engraved on the back with the line the house was founded under: Master of Complications. Silvered dial, applied gold batons and a sunk small seconds, on its original Franck Muller gold buckle.
The hour markers are faceted gold batons, applied rather than printed, with twelve doubled, and an outer track of dots runs round the edge with a gold dot at each hour. The small seconds is sunk below the main surface, its centre turned with fine concentric guilloché inside a railway track, a different texture from the matte field around it. A thin gold line is printed between the dot track and the batons, and the sunk seconds dial is edged with a narrow gold rim. The hour and minute hands are gold leaf, long and slender, with a matching gold seconds hand that carries a short pointed tail as a counterweight. Several of the applied batons have taken on a light patina, which shows against the clean silvered ground.

The case is 34mm across and 39.75mm from lug to lug, three-piece, with a stepped bezel and lugs that curve down to the strap. It is a small, flat case, just 6mm thick. The fluted gold crown is signed on its face with the FM monogram, and the back is brushed rather than polished, the plain ground for the engraving set out in the Record.
The watch comes on a brown calf strap fastened by its original Franck Muller pin buckle in 18ct gold, with two grooves running round its frame and stamped 750 with the FM monogram on the underside, matching the gold of the case.

The caseback is stamped FRANCK MULLER GENEVE in two arcs at the top and engraved with the house motto, Master of Complications, in script, the case number 03 and the reference 1900 S6, beside the 750 fineness mark and the Helvetia head assay mark, in use on Swiss gold until 1995. The dial and the FM monogram crown are signed, and the 18ct gold pin buckle is stamped 750 with the FM monogram. The case number places the watch in the first production of the reference, in the early 1990s.
