All common ways to look at time and some uncommon ways are quite natural at this point but for many years the comfort was with a few mechanical watches I own.
I've bought, sold and retained some nice mechanical watches since I was a teen. I had some digital watches and later on solar including a nice threaded crown dive type. Apple Watch has had them all in storage for 2+ years now. I remember being a thrilled kid with my first Timex. Now my watch is my telephone, one of my computers, and a FDA approved ECG device.
Work collaboration with people around the world helped change my 12 hour analog mind.
I usually set electronic or digital clocks to 24 hour mode. In the work day I often switch my watch to the info graphmode.
