I thought this Forum needed some interesting news. And I’m here to provide it!


My Chronometre Souverain ran almost 66.5 hours without rewinding. Additionally, and this is the truly interesting part: 64 of those hours ran within chronometric standards. A mere 3-4 seconds faster than at the end of the 64 hours.
I can’t vouch for the last 2 hours-I fell asleep.

The CS had longer, and more accurate, autonomy than my Optimum.
