Grand Seiko SLGB003 UFA

Seiko finally added thermocompensation to their spring drive movement.
Claimed ±20 spy.

I tried one on.
It's nice, although for me it was slightly too small, and I prefer dark dials.
Spring drive movement is lovely to look at and putting the rese…

Culture of precision in 1967

The holding of chronometer competitions in such a public way to the late 1960s may have had commercial motivations, but that very motive, and the gusto with which companies participated, is based on a premise that accurate time was valuable.

This cult…

New UFA

Inhibition and Quartz Testers

In another thread I made some rather unflattering remarks about the oscillators in my two MoonSwatch watches. No, the MoonSwatch isn't HAQ, but this thread isn't really about the MoonSwatch, it's about the source of my initial mis-apprai…
