Possibly B-Ware.

The clock that I have received has average daily deviation of about -5 seconds.

However, the hour hand is unfortunately somewhat offset. When the minute hand is already on the 12 o'clock indexes on the dial, the Studen pointer is already well above the respective indices of the hour that dawns just. In addition, the ring is inside the case, on which are the second indices, slightly twisted.

In addition, the warranty card does not have a stamp, making it useless, according to some Internet forums.

Nevertheless, I'll keep the clock because I'm used to the little quirks.
