The date code on the movement is L9, the date code on the case is M3. The list of Bulova movements on the myBulova site does not include a 23J 11AC, although there was some discussion of this movement on the forum in January 2016. I purchased the watch at a second-hand shop around 2014-2015. I replaced the crown, which was missing. Other than that, the watch is as I obtained it.
Case Serial No.
