Hi nice watch! So familiar to me. I have two of these one in steel with the dark and light blue two tone dial and original steel bracelet the other is gold plated with a brown and black two tone dial on leather. Difference is they are both N4 and both 23 jewel automatics serial numbers: steel: 3856285. gold plated: 3745365. Lovely watches. I'll be posting some pics when both watches are in the same room so to speak. I havent seen either of these anywhere apart from here with this 17 jewel version. Both watches running well. I'm actually looking for a UB for the gold plated one as someone in the past fitted one that isn't quite the right size. Not a common UB shape. Anyway if anyone could help I would really appreciate some info on this. Thanks everyone Happy new year.
