一直有這個好奇,終於找到答案了:
所有GS手錶都有四個英文字母
第一個字母一定是S (Seiko)
第二個字母B-男錶尺寸 T-女錶尺寸
第三個字母G -Grand Seiko
第四個字母開始有意思了:
A = Spring drive, date: 9R65 or 9R15.
B = Spring drive chronograph, date:, 9R84
C = Spring drive chronograph, GMT, date: 9R86, 9R96
D = Spring drive manual wind 8 days, 9R01 (upcoming)
E = Spring drive GMT, date: 9R66
F = Quartz, date: 8J56 (discontinued)
G = Quartz, date: 8N65 (discontinued)
H = Hi-beat automatic, date: 9S85, 9S85 Special
J = Hi-beat automatic, GMT, date: 9S86, 9S86 Special
L = Automatic, PR, date: 9S67 discontinued
M = Automatic, GMT, date: 9S66, (9S56 discontinued)
R = Automatic, (date, 9S65, (9S55 discontinued)), no-date 9S64, (9S54 discontinued))
S = Quartz, no-date: 9581 (discontinued)
T = Quartz, date, day: 9F83
V = Quartz, date (larger calendar): 9F82
