RARE Vintage Bulova Computron N5/ Accuquartz 228 Big Block RED LED Watch w/ Original Case/ Box. Fantastic watch for collector. I bought batteries for it and it turns on, keeps time, but I have a hard time setting the time since I don't know much about the watch works and how to set it. Marked on back Bulova N5, number I 948879, 10k R.G. P. back, in great condition for the age, some patina on the case. Face of watch measures 1.75 x 1.5 inches, total length with bracelet closed 8 inches but adjustable. Clasp works very well. Watch in great condition for age, rare and hard to find! Fantastic watch for collector!
