When I first purchased my Sinn U1, there was no chance in hell I expected it to be the most accurate watch in my collection. Boasting a Sellita-200, I expected the ETA clone to be inferior and no where near as accurate as it turned out to be. Compared to my Breitling, Tudor, and Rolex movements, this Sellita movement has been a rock steady +1/2 sec/day (if that) for 25 days and counting.
A welcomed and pleasant surprise. Would be interested to hear some of yours.
