I've always had massive issues getting to sleep (still do), and consequently waking up again in the morning. A couple of years ago I inherited my Grandparents clockwork pendulum clock which ticks quite loudly and also chimes the hours and a single chime on the half hour. I still have an alarm set on my phone just in case, but after a couple of months I found myself consistently aware that I've woken up naturally before my alarm has had a chance to go off. And as I'm not shocked awake by the alarm I'm feeling a lot better on a morning because of it. I can only assume that I'm subconsciously aware of the time passing and what time it is from the chiming, rather than a period of obliviousness and then a sudden shock. If I forget to wind it so it stops I tend to sleep in late and get woken by the alarm. I do find it slightly surprising as I used to be one of those people where a ticking wristwatch wrapped in a sock in the bottom of a draw on the other side of the house would keep me awake when I was younger. Having the wall clock audibly ticking across the house has actually become quite calming and soporific.
