Why wear a watch when I have the time on my phone?

As a “technology person” (ugh), people ask my why I wear a mechanical watch when I already have the time on my phone?

I love mechanical watches for a number of reasons – the art, the science, the ingenuity behind the mechanisms, the continuation of a craft dating back centuries, the look, the feel, the freedom from batteries and tethers and cords.

But lately it’s really come down to this: When I look at my watch, it gives me the time. It asks nothing in return. It’s a loyal companion without demands.

In contrast, if I look at my phone for the time, it takes my time. It tempts me. The time is paired with notifications. The time is paired with a big color screen. The time is paired with a temporary cure for boredom. It seduces. It’s a rare moment that you look at your phone and you only see the time. I don’t like that trade.

I use my phone when I need what my phone does. I use my watch when I need the time. I like being on time, I like knowing where I stand in the hour, in the morning, in the afternoon, in the day. I look at my watch a lot, and I just love that it doesn’t look back.
