Catalog's shortened ref '7640-41' doesn't cleanly match Oris's full reference format (e.g. 01 735 7640 4164-...) -- treated as single_source given real match uncertainty. One Chrono24 listing for a specific full ref in this family showed $1,872, treated as an outlier (likely a different, non-comparable configuration) and not used. This model appears discontinued from Oris's current lineup -- secondary_used is the applicable channel.
