Unknown source of hourly alerts on apple watch
My Apple Watch 3 beeps every hour. I have looked at all the notifications and turned most of them off, and set others to no sound, but the watch still beeps. I use an iPhone 6 and both watch and phone are up-to-date on their OS. I just can't find the cause of the alerts. There is no notification that comes with the alert, so there is no clue to the source. Any ideas of what may be causing it? Any way to locate it (without turning off ALL my apps, and then turning each one back on one-by-one)? I must be overlooking something, but I don't have reminders set up, and I have searched every app to see any possibility with no luck. I have nothing set up in "Clock". Could it be hidden somewhere? Thanks for any suggestions for how I might locate it without going to too much trouble.
