Which movement is the most accurate?

In general, quartz movement is more accurate than the mechanical and automatic movements. Accuracy measures the amount of time gained or lost by a timepiece within a specific period of time, usually 24 hours. It is common for watches to have some variation in timekeeping and a watch model is deemed accurate if it gains or loses the same amount of time every day.

The average quartz watch has a variance of 0.5-2 seconds per day.

The average mechanical or automatic watch has a variance of 3-5 seconds per day.
