Dial Display and Calendar Indicators

The dial displays a grey sunburst fumé finish with applied baton markers and a cursive maker signature. Visual observation confirms a date window at the 4 o'clock position displaying the numeral 18, set diagonally symmetrical to a curved power reserve indicator.

A miniature red-tipped central arrow indicates the month using the twelve standard hour indices. The dial is completed by central hour, minute, and sweeping seconds hands, without traditional perpetual calendar subsidiary dials.

  • “The date window peers out at you from the 4 o’clock position, diagonally symmetrical to the power reserve indicator.”
  • “The hour indices have two roles here – measuring the traditional lapse of the hours in a day, but also doubling as indices for the 12 months of the year – with a small red and white central arrow indicating the current month.”
  • “Grey fumé sunburst dial with applied baton markers and subtle cursive maker signature”
  • “Slanted date aperture at 4 o'clock displaying numeral 18”

Reported Movement and Accessories

The catalog entry states that the piece is powered by the manual-wind Calibre HMC 812. The text describes an open caseback revealing the leap-year indicator on the reverse of the movement, along with bidirectional setting capability for the date and month, though the movement and caseback are not visible in the provided primary image.

Accessories recorded with the piece include an H. Moser & Cie. guarantee, instruction booklets, a cloth, tags, and an inner box. Individual serial numbers for the case or movement are not recorded in this source.

Evidence for this section
