備註/Remarks:
There are only two model of Seiko 5 has been found which carry with a quartz movement. They are 5Y01 & 5Y13A. It’s still a mystery to collector - Why Seiko made these 2 aliens? When first “5” series launch to the market, Seiko had explained the meaning of “5” to public - They are (1) Waterproof, (2) Anti-shock, (3) Automatic, (4)with Date and (5)Day appearance. Were Seiko forgot?
精工5為普及機型, 推出市場時層經對市場公開解悉”5”的含意, 即 (1)防震, (2)防水, (3)自動, (4)日曆, (5)星期顯視.。現時只發現兩款同期的石英機種的精工55Y01, 5Y13A, 到現在都無法知道精工廠製造這兩款表的原因, 是換換口味還是忘記了?
