Apple

I am looking for a vibrating alarm that can actually wake me up. I often get insufficient sleep and consequently am sometimes not easily woken by vibration from my nearby iPhone SE 2020, nor by this https://www.amazon.com/dp/B0CK4X44SJ vibration alarm watch, which hasn't worked for me and which I am going to return. I'm hoping that a cheap Apple Watch SE (thank you, u/Responsible_Goal_360 for the tip that Wal-Mart will have one for $179 this week!) can be programmed with repeated vibrating alarms that will eventually wake me, without disturbing my bed partner.

Currently I use the iPhone to have a vibrating alarm, then 5 minutes later a gentle instrumental song alarm, then 5 minutes later a typical still-gentle lyrics song, and that has generally worked for me. However, I'm hoping something similar will work (potentially with increasing strength of vibration, which allegedly may be possible), and will appreciate experienced/knowledgeable comments about such.
