EDYYWWDNN
where,
YY = year (04-present)
WW = week (1-52)
D = day (1-7)
NN = number instrument produced that day (1-99)
for example,
ED0940201
would indicate the 1st instrument manufactured on the 2nd day of the 40th week of 2009.
其實就是查了國外網站的資料,WW是指一年有52周,他是第幾周去看
不過我看了一些網站,並沒有直接指出前面不是寫ED就是假
倒是我今天留意了我們店裡的幾把EDWARDS,的確都是ED開頭
僅供參考
