I've found it the official mougino's birth year watch!
A splendid Seiko Type II from 1979, in great condition: nice 40 x 35 mm TV cream dial with a slight patina, perfect black stick indices for an outstanding legibility, the crystal might need a rub of Polywatch otherwise it's totally acceptable, and of course it's a quartz so I've set the day and date once and now it's a grab'n go! and cherry on the cake: it comes with a perfectly sized vintage Seiko-signed bracelet!
I'm on my little cloud right now!
And without further ado, some pics:
