A simple function check indicated the movement runs; accuracy, power reserve and long-term performance have not been tested and servicing may be required at the buyer’s expense. Water resistance cannot be guaranteed and should be checked by a qualified watchmaker before any exposure to water. Pictures of the movement are available upon request. No right of withdrawal applies to live auction purchases.
Omega used two case makers for the 105.012: Huguenin Frères (HF) and La Centrale Boîtes of Biel (CB). The CB cases—seen only on the sub-reference 105.012-66—are identifiable by a subtle extra facet: a fine line between the polishing planes on the tops of the lyre lugs. Many examples lost this detail to polishing, which makes crisp CB cases particularly sought after.
