That Apple Watch on your wrist feels like a smart habit.

At your level, it's one of the least intelligent things you can wear:

The Apple Watch had good intentions. It got millions of people used to wearing something on their wrist again. For the general population, that's a net positive.

For someone in a senior position, it's mostly a distraction.

You glance at it mid-meeting and what does it show you? A notification that just scatters your attention.

During a workout? Calories burned. A number that tells you nothing about your health and happens to be wrong anyway.

Stanford tested seven of these wrist trackers against lab-grade equipment.

The most accurate one was still off by 27% on calories burned. Some by more than 90%.

So you're breaking your focus to read a number that's just noise.

And calories burned tells you nothing about whether your body is getting healthier or performing better.

That's like celebrating website traffic while revenue quietly falls. A number that feels like progress and pays for nothing.

Then there's the rest of it. Notifications. Messages. A buzz on your wrist every few minutes pulling you out of whatever you were doing.

Your attention is the most expensive thing you own. The watch on your wrist should protect it, not tax it.

That's the case for a mechanical watch. It does one job. It tells you the time, and at a certain price point, it reminds you how valuable yours is.

My Submariner has never once interrupted a meeting. I bought it because I wanted a reminder that my time is valuable.

I'm not against data. I'm against bad data delivered badly.

So I do both. The mechanical watch on the wrist, and a screenless ring for the data that matters.

I use the Ultrahuman Ring Air. No screen, nothing to glance at, nothing to interrupt me. When I want to know how my sleep and recovery are trending, I sync it once and review it on a Sunday.

Once a week. Not twenty times a day.

Because the data on your wrist is a fraction of what actually matters.

That's why I built the Performance Index. It combines the data that does:

→ Comprehensive blood work

→ A body scan via DEXA

→ The 3 metrics from your wearable that actually matter

Combined into one dashboard that shows how your body is really operating.

These are the Body KPIs worth caring about.

Reviewed periodically and strategically. Not obsessively.

Let the watch on your wrist go back to the one thing it's good at: Protecting your time.
