人类在空间和时间中生存。空间的存在很容易被感知,但我们却不容易感知时间的存在,所以只能用工具来测量它的流逝,人类也因此发明了计时器。从沙漏到日晷、从原始钟到高级手表,人类不断改进计时器的精确度和艺术性。从最古老的计时工具到今天制造出的每小时机芯振频为28800摆的各种卓越钟表机械,时计已经走过了好几个世纪的历史。一提起钟表,人们就会自然而然地想到瑞士;一提起瑞士 Humans live in space and time. The existence of space is easily perceived, but we are not easy to perceive the existence of time, so we can only use tools to measure the passage of time, so humans have invented the timer. From hourglasses to sundials, from primitive clocks to high-end watches, humans are constantly improving the accuracy and artisticness of timers. From the oldest timekeeping tool to the hourly movement today, which produces 28,800 pendulums, the watch has gone through centuries of history. Mention Switzerland naturally when mentions the timepiece. Mention Switzerland
