- Dial Design and Display
- The timepiece carries a white opaline sector dial featuring foil applique numerals and blued steel leaf-style hands, supplemented by a central chronograph seconds hand. The dial is printed with an outer tachymeter scale executed in blue. Two small chronograph subregisters are positioned at the 3 and 9 o'clock markers to support chronograph and running indications. Centrally, the dial display bears the printed signatures 'CHRONOMETRE' and 'IMPERIOS'.
- Reported Movement and Catalog Limits
- The catalog description lists a manual-wind 'Hahn Landeron' column-wheel movement providing time and chronograph functions. However, internal movement and inner caseback views are not included in the auction imagery, leaving the specific caliber stamping and mechanical integrity unverified by direct observation. The approximate dating to 'CIRCA: 1930s' and the attribution of the brand to La Chaux-de-Fonds, Switzerland, derive entirely from catalog statements. Additionally, the auction house terms explicitly state that timepieces are sold without warranty of working condition.
- Case Architecture and Visible Condition
- The watch features a 38 mm metal case recorded as case number 176114, combining chrome- and gold-plated metal with a steel caseback. A single chronograph operating pusher is positioned above the winding crown at approximately 2 o'clock, reflecting its monopusher configuration. Articulated wire-style lugs are hinged onto wide fixed end-pieces that extend from the rounded case body. Visual inspection demonstrates noticeable surface wear, including plating loss across the bezel, while the watch is mounted on a black leather strap.
