備註/Remarks
Seiko Crown line (1959-65) was the Seiko's deluxe and Hi-end watch line when Grand Seiko line has not been invented. They are mainly in 3 categories, 19J, 21J & 23J Special.
This is a big size 21J version and has the same watch case size of Crown Special with a 37mm diameter. For the normal 19J version, it has 35mm only. Since not much people familiar with the vintage Seiko, I can still find Seiko Crwon selling at Ebay with a very reasonable quite often.
