The model is a NH3420 but there isn't much out there with regards to information. I believe they came in black and white too. Its a bit of a rare beast but wasn't an expensive watch when first made. Probably about £140. Punches well above its weight for that though.
Sounds about perfect. I have small wrists and struggle to find modern watches that aren't too big. Any idea how I might track one down or something similar?
That's a very nice watch!
The NH3420 seems to be really hard to find. Earlier this year Citizen released a similar JDM watch at 38mm, the NB1050-59L. I also have small wrists and prefer 36mm, but this version works (just barely) for my wrists.

Second Setting - the Japanese Railway watch. This also happens to be my birth year and was used in the bullet train "Shinkansen" division.

These are nice. I like the simplicity and I believe the movement is the same one that powered a lot of HMT watches. Simple but reliable.

looks good. Which Showa year if I may ask?
