1966年,芝柏率先推出36000A/H机芯,大幅度提高了手表的精确度。
1967年由Neuchatel天文台发出的认证中,70%由芝柏GP独占。
那么,关于芝柏表的高频机芯,市场上有不同的说法。
我去信咨询了芝柏官方,问他们在芝柏历史上都出过哪些36000高频的机芯,他们的答复如下:
The HF calibres (High Frequency, “Haute Fréquence” in French) were the movements with 36,000 A/h (5 Hz).
Actually a couple of different but similar versions were introduced and produced between 1966 and 1970:
GP 30-5, GP 30-7, GP 31-7, GP 32-7, GP 32-A, GP 42-0, GP 42-1, GP 42-4, GP 44-0, GP 44-1.
All of them were on A. Schild (AS) basis.
The production of mechanical movements was then almost stopped in favour of the more precise quartz movements with a frequency of 32,768 Hz (compared to 5 Hz for a mechanical movement). |
