yes I understand that you want it precisly, but it doesn’t matter (really, doesn’t matter at all, read my post), and its more useful if you can change it quikcly without having to spam a button.
About ISO, the wikipedia page :
https://en.wikipedia.org/wiki/Diving_watch#ISO_6425_standard_for_diving_watches
https://en.wikipedia.org/wiki/Water_Resistant_mark
Specifically says that ISO 6425 is for Diving watches, starting at 100m
Quote :
ISO 6425 defines such watches as: A watch designed to withstand diving in water at depths of at least 100 m and possessing a system to control the time.
So no, a 30m rated watch like the Core 1, or a 50m rated like core 2 is NOT ISO 6425 compliant, it can’t be by the very definition of it
I think the service center is saying that the watch is tested “like the ISO 6425” in the way they test it a 125% of rated depth, but its not 6425
