I'm not that sensitive to errors, but I think I measure the errors once I get a new watch. It is difficult for the general public to have error measurement equipment, so it would be of great help if you could provide guidance on how to measure it yourself.

The first thing you need to know about the daily error of a watch is that simply checking the daily error is insufficient information to check the condition of the watch. When checking the error in VIVER, I always check the overall condition along with the amplitude (vibration angle) as part of the overall condition check.

However, if you want to measure the daily error at home, it is recently possible to measure it through a mobile phone application. Of course, the accuracy of the application cannot be guaranteed. The most classic method is to set the time on your watch accurately at midnight or a specific time, live your life as usual, and check the difference at the same time 24 hours later to see the daily error within your daily life range.
Please note that watch condition checks are provided free of charge at the VIVER showroom.
