因為你擺個角度唔啱
例如網上搵到 ORIS squid GMT
Deviation in seconds per 24 hours (Fully wound / after 24 hours):
Dial up: +0.2 / +1.2
Dial down +5.9 / +8.2
Crown up: +5.6 / +6.6
Crown down: +5.1 / +8.4
Crown left: +12.4 / +16.1
Greatest deviation: 12.2 / 14.9
Average deviation: +5.8 / +8.5
如果呢隻你錶面向上平放,咪天文台錶咁準囉。 你戴住成日,個position會成日改,平均翻。
