- Case Form and Dimensions
- The timepiece features a compact circular case with narrow wire lugs and a fluted winding crown situated at the 3 o'clock position. The seller lists physical dimensions of 27.3 mm for the case diameter, 29 mm including the crown, 30.5 mm lug-to-lug, and a thickness of 8.4 mm, with a lug and band width of 10 mm fitted with a black leather one-piece strap. The specific case metal composition is not identified in the listing. The interior case markings are reported by the seller as 'E.F.Co. LONGINES Fab. Suisse 5406970', sharing the serial number ascribed to the movement.
- Reported Movement and Dating
- The seller documents the internal mechanism as a manual-winding Longines caliber 10.68Z (also designated by the seller as Z89 or Longines 10L) with serial number 5406970, dating the watch to 1935. Because movement and interior case back photographs are not present in the record, the caliber identity, mechanical condition, and reported serial numbering are source-reported and cannot be independently confirmed from the visual evidence.
- Dial Configuration and Visual Aging
- Visual observation shows a patinated beige dial marked by extensive surface mottling, aging, and darkening. The layout includes bold printed Arabic numerals, an outer minute track, and blued steel hour and minute hands. A subsidiary seconds subdial sits at the 6 o'clock position, marked with Arabic numerals at ten-second intervals. Dial signatures include 'LONGINES' beneath the 12 o'clock marker and 'FAB. SUISSE' printed along the perimeter below the subdial.
