The timepiece features an ecru-toned dial with a vertical bi-compax layout. It includes a 45-minute chronograph register positioned at 12 o'clock and a continuous running seconds subdial at 6 o'clock.

The dial displays Arabic hour markers and syringe-style hands described as having lume. The outer perimeter of the dial features telemeter and tachymeter scales, protected by a Plexiglass crystal.

Movement and Specifications

The watch is described as containing a 17-jewel manual-wind Venus 170 mechanical movement. The technical documentation provided by the seller lists a power reserve of 40 hours.

These technical details regarding the movement and power reserve rely on seller documentation and cannot be verified through visual inspection of the watch exterior.

  • “Jewels 17j”
  • “Winding Manual”
  • “Power Reserve 40 hours”

Open research questions

  • Is the vertical 45-minute register at 12 o'clock a standard feature of the Venus 170 calibre or a specific Eloga implementation?
  • Can the discrepancy between the 'White' dial color in the specification table and the 'Ecru' dial description in the text be reconciled?
