The new 16-digit references are for the standard Moonwatch models that come with the new packaging and a new $750 price increase. These newly packaged Moonwatch models are in the pipeline for delivery any day, so this is the last of the old references with just the watch (and the old prices).
The four new references and new retail prices are:
Omega Speedmaster Professional 311.30.42.30.01.005 (HES / Br) - $5,150
