The Swiss Observatory uses cameras and computers to analyze data in complex vibration tests. There are 7 tests in total. Failure to meet the minimum standards for any test will mean rejection. The test is very complicated, and the following is just a simple summary attempt.
Test 1: Average Day Difference Rate: After a 10-day test, the average day-to-day difference of the movement must be within a range of minus 4 seconds and plus 6 seconds per day. The Swiss Observatory determines the average daily difference rate by observing the time indicated by the time and the time indicated by the movement 24 hours ago.
Test 2: Average daily variation: The Swiss Observatory will observe the movement rate (two horizontal positions, three vertical positions) from five different positions, once every day for 10 days, for a total of 50 speeds. The average daily variation cannot exceed two seconds.
Test 3: Maximum daily variation: 5 times in 5 positions, where the maximum daily variation cannot exceed 5 seconds per day.
Test 4: Level difference and vertical difference: The Swiss Observatory will subtract the average position of the vertical position (first day and second day) by the average rate of the horizontal position (ninth and tenth days). This difference must be in the range of minus 6 seconds and positive 8 seconds.
Test 5: Maximum deviation rate: The difference between the maximum daily difference rate and the average test day difference rate cannot exceed 10 seconds per day.
Test 6: Temperature-dependent deviation rate: The Swiss Observatory tests the movement rate at 8 degrees Celsius (46 degrees Fahrenheit) and 38 degrees Celsius (100 degrees Fahrenheit). He subtracts the cold temperature rate from the hot temperature rate and divides it by 30. The deviation cannot exceed 0.6 seconds per day.
Test 7: Recovery rate: This is obtained by subtracting the average of the average daily difference rates of the first two test days from the average daily difference rate of the last test day. The recovery rate cannot exceed 5 seconds. This is simple, isn't it? If a movement can meet these standards, the Swiss Observatory will issue a certificate called “Precision Chronograph”.
