Source note
All figures follow WatchBase and describe only the references sampled here; they have not been checked against the manufacturer's archive. WatchBase, an online database of watch references, lists 4 references under this family name; this entry summarises 3 of them, chosen across that list, including the reference originally recorded for this entry. The reference list, calibres and case specifications summarised above come from WatchBase; the manufacturer's own archive or a printed reference work should be consulted before treating any detail as definitive. WatchBase does not record production years for the references sampled here, so the family's introduction date and production span remain Research Required.
