It's just cool. I suppose there's not a lot here to review, because it's a clock on the side of the road. But it IS the USNO master clock, so that's really cool. And yup, my Apple watch matched it. :

It's a large digital clock clearly visible from Massachusetts Avenue in both directions. Only displays seconds. As a cult destination nowhere near as cool as Sonny Bono Park.

Great experience I was there on June 2 2022. This date will never repeat itself

Was going to go see it but didn't have the time

made it just in time

Always on time.
