Watch will randomly lock itself

[Endorphine88]

My watch will randomly lock itself only when I wear it on my left wrist. I wear it pretty snug with any band that I am using (my daily go-tos are the classic leather one from Apple and I switch to a silicone band when I go to the gym). I don't understand why it only happens on my left wrist and not the right at all. I have wrist detection and unlock with iphone enabled and I have it set to left wrist orientation with the crown facing in (left side).
Anyone experience this ?

I tried using the lock function but dumped it after my watch locked several times. I do not and will not wear my AW4 tight, just enough for the sensor to work most the time.

How's the heart rate feature working? Just read another thread on locking:

Do you have tattoos where you have the watch?

Actually I do. I have a semi-sleve on my left arm and a part of it is under the watch. Does that matter?

Yes it matters. A tattoo, especially a dark one, will prevent the sensor from being able to read your HR.

My sister has a sleeve and it locks randomly.

Yep it can not read your HR, it will lock the watch if you have that feature turned on.
