Object description

Case and Dial

The watch features a three-body, 18K pink gold case, finished with a combination of polished and brushed surfaces. It incorporates curved straight lugs and a sapphire crystal. For user interaction, a push button for date correction is positioned at the 10 o'clock mark. The reverse side of the watch utilizes a transparent case back secured by six screws to reveal the movement.

It features applied radial Roman numerals and indexes. Specific functions include a subsidiary seconds dial at the 5 o'clock position, a power-reserve sector at the 3 o'clock position marked 'AUF' and 'AB', and an oversized date aperture at 1 o'clock. The display is completed with pink gold alpha-style hands.

  • “push button at 10 for the date correction”
  • “Solid silver, off-center hour dial with applied radial Roman numerals and indexes”

Movement and Escapement

The timepiece is powered by the Caliber L 901.0. This manual-wind movement features fausses cotes decoration and includes 53 jewels, nine of which are set in screw-mounted gold chatons. The movement incorporates a straight-line lever escapement and a monometallic balance adjusted to five positions.

Technical regulation and timing are managed by a swan-neck micrometer regulator, a self-compensating flat balance spring, and a shock absorber. The balance bridge is notable for its hand-engraved finish, a traditional aesthetic element of the Glashütte manufacture.

Condition and Attribution

The watch is accompanied by its original fitted box. The auction description assigns the piece an overall condition grade of 'AA', describing it as very good. Specific observations regarding the case indicate it is in very good condition with slight scratching present.

  • “Overhaul recommended, at buyer's expense”
  • “HANDS Service hands”
