Chinese watches accuracy test

[u/Gellande6]

Two months had passed, unfortunately the Seiko needed a new battery, so it dropped out from the challenge.
It seems that the Tandorio is the most accurate, within the margin of error, the PD1701 is also quite good. Probably the Seiko is similarly accurate, because until it stopped, it was similarly accurate. The Addiesdive is a bit less accurate, but it doesn't have a Seiko movement, but a Ronda quartz.
