Do You Wear a Wristwatch When You Ride?

It has classic analog movement with precision based on the Universal Clock. It also automatically self-adjusts for latitude and season. It never needs to be reset for time zones. No batteries or winding needed. It is accurate for within sub-time zones. And it cannot be hacked.

My spherical compass shows angle of inclination too.

Well, not really.
It's weighted.
But It would spin in circles standing on the magnetic North Pole.

In Australia, it would spin backwards on the wrong side of the road.

If so, which one and what features do you use?

If it's getting dark, I go home.

Casio F91W, in production since 1989. I have discovered again and again and again, everything designed since then has been to appeal to a market less sophisticated than myself.

I wore a Casio calculator watch for more than two decades,..

I met someone with Casio Scientific Calculator Watch.

It kinda blew my Fricken mind!!
Too Damn Cool,..

It could do calculus, algebra, and functions/relations, all on your wrist.

My first calculator had tiny fluorescent tubes to light the segments of digits. Before that, HP calculators were costly and primitive. I'd seem only one, when, far away at sea, I had to calculate a complex resistor network to troubleshoot an intermittent navigational radar that had stumped a team of electrical engineers with carts of sophisticated equipment. They'd replaced $100,000 worth of parts to no avail. ($750,000 in 2026.)

I wished I had my slipstick, but it was ashore, where prolonged humidity was warping the wood, ruining it. Fortunately, I knew all kinds of ways to cheat because with my very limited attention span, cheating was the only way I could have passed 5th-grade arithmetic. By cheating, I filled a legal sheet, 8.5 x 14", in only 20 minutes, with expected ohmmeter readings. From there, it took only a minute to find the problem, a faulty resistor whose replacement cost a penny.

If it's worth calculating, it's worth using a slipstick or 5th-grade cheating. Forget gimmicky wristwatches!

This was my first calculator,..

It had an LED display that ate up a 9V battery every couple of weeks.

I knew them as slide rules.
They were about 5 years before my time.

I had a calculator by grade 9 and had to do math long-hand before that.
