OM is a label that public dealer write-ups attach to complications and dress watches at the upper end: Speedmaster and Seamaster references from Omega, a Jaeger-LeCoultre Master Calendar, a Blancpain Villeret and a Royal Oak chronograph from Audemars Piguet. One of those articles sets the same Blancpain Villeret reference against two other labels in a side-by-side comparison of build, price and movement, which is a useful picture of how interchangeable the names become once several sellers stock one reference. Our own sample carries no listing under this label.
