It has the ST2130 movement, which beats at 28,800 bph / 8 bps. It looks stunning and I love it.
Oddly enough, it’s half the price of the 816.351, even though, at least in my opinion, this one looks nicer.
So far, it’s 6 seconds per day fast, but constantly, so that’s very good news.
The clasp has two releases at the sides.
Let’s hook it up to a timegrapher and see how it ticks.
|Position||Accuracy s/day||Amplitude||Beat Error|
Overall, not shabby. I correct my watch by putting it face up overnight when it’s too fast, and crown left when it’s too slow. For more drastic corrections, I use face down / crown down. This way, I keep the watch within 2 seconds accuracy.
