Identity and Case Construction

The catalog listing describes the piece as an Eberhard Pre-Extra-Fort chronograph wristwatch housed in an 18k solid rose gold hinged case measuring 40 mm. Visual inspection confirms the front of an 18k gold case, although internal hinges or caseback hallmarks are not recorded in this source photograph. Operating controls on the case band comprise a fluted winding crown flanked by an upper oval button at 2 o'clock and an oval slide at 4 o'clock. According to the seller, the 2 o'clock button functions as a start/stop/reset control, while the 4 o'clock slide halts and restarts the chronograph without resetting the recorded elapsed time.

Dial Configuration and Visual State

The dial is described as originally ivory, signed by Eberhard & Co and marked 'Swiss-made', bearing baton markers for the hour plots and darkened baton hands. Direct observation confirms aged spotting and discoloration across the face, described by the dealer as an attractive 'newsprint, sepia' patina. The dial incorporates two sunken engine-turned subsidiary dials: constant seconds at 9 o'clock and a 30-minute counter at 3 o'clock. Surrounding these registers is an outer telemeter scale and an inner spiral tachymeter scale.

Documentation and Movement Observations

The seller dates the watch to circa the 1940s ('c.1940s') and assigns it a condition rating of 8.5/10, though dealer condition scores are subjective commercial assessments rather than verified facts. The listing notes that both original box and papers are absent ('Box/Papers No/No'). No internal movement photographs, caliber designations, jewel counts, or case reference numbers are recorded in this source. The watch is shown fitted to an attached brown textured leather strap.
