The day and month indicators are not very readable in the dark, although for now it has sufficient lighting. The Bluetooth and the application work very well.

A great watch. Flawless. I don't pay any attention to my watches at all, and so far I haven't managed to scratch it, neither on the crystal nor anywhere else. Whenever I remember, I will do some synchronization, but in practice, I haven't noticed that it needs it. I wear it in winter and summer, everywhere (office, field, sea, mountain). Because I am also an amateur handyman, I often work with tools that cause vibrations in my hand. Absolutely no problem.
The only complaint, but it doesn't bother me much, is that I can't read the digital indicators comfortably, I have a certain age.
I used to be a fan of automatic watches before this one. I don't see myself going back. Not at least for a watch purchase that you simply want to wear and do its job without much fuss.
At some point, I see myself even hitting a frogman
