Some of us just want to know what time it is without pulling out our cell phones.
I used to have an employer that would give me a 15 minute break at random ass times like 9:07am and tell me to return 15 minutes after and I’d be pulling out my phone every 5 seconds and doing math. So I just got a cheap watch and sent my time to the same time as their clock and voila, I was a great employee.
