Product works great BUT has gradually gotten louder...  Not significantly but does rise a concern.
I've read on previous posts that due to larger watches, it does work "harder" thus becoming louder.  In my case, this noise was gradual, not from the get-go.

My watch is only 41mm and 16mm thick.  I hope it doesnt die on me, only time will tell.

Ping me and I will respond with an update.

Regards.
