The calibration result of the Omega Seamaster series 220.10.41.21.01.001 shows an average of 1.3 seconds fast per day after 31 calibrations (15 days). Due to factors such as watch power and time span, this calibration result is for reference only.
I have been wearing a Seamaster 150 black dial for over half a month. The daily error was not very accurate for the first day or two, about +2 to +3 seconds per day. I then started to measure it daily, with a measurement interval of 12 hours.
Wear the watch normally during the measurement period and wear it at all times except when taking a bath (including sleeping at night).
A total of 40 sets of data were measured over 20 days. The overall error fluctuation is very smooth. The average daily error is about +1.1 seconds. It can be seen that the mean square error is also very small, indicating that the daily travel time is very stable and does not appear to be fast or slow, thus proving that the performance of the 8900 movement is indeed very reliable.
I went to the forum before and saw some comments saying that after wearing it for a month, it can still run smoothly, so I also want to see how the error of your 8900 movement is.

I struggled for a long time and read other people’s reviews every day before finally deciding to buy the watch here. I have been wearing it for more than 2 months now. There is no problem with the watch and the time is very accurate. My wife said I bought the right watch.
