kevinevansthe first on model number is :96B229. not sure about the others. The movement is the proprietary UHF ( Ultrahigh frequency), 262 khz quartz movement. This the same movement used in Accutron II, and precisionsit watches. It differs form typical quartz by being very accurate long term , and by the smooth sweep of the seconds hand, mimicking the smooth sweep of mechanical watches.
This is a solid discount as far as I can tell. Bulova is now owned by citizen, HQ in NYC though.
