- 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 10 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. That figure is not necessarily the family's introduction date: earlier references may exist outside the sample, and WatchBase coverage of discontinued models is uneven.
