I was recently browsing some vintage Orients. Some of the ones with day-of-the-week complications actually displayed the day in Japanese (see pictures).
Does anybody happen to know of any more JDM watches with day complications written in kanji? I think it's pretty cool as it showcases the heritage of the watch and outwardly marks it as JDM. Unfortunately I searched around a bit for day complication watches on Amazon.co.jp and they all had SUN / MON / TUE so I'm afraid it might be rare.
I speak business-level Japanese so I don't think it would be pretentious of me to wear one.
P.s. Are these vintage Orients in the pictures restored? They look a little too good for 1960s models.
