I just had the strap changed on my Sinn 856 when I noticed that it didn't have "SUG Germany" engraved on the case at the 6 o'clock position. Now, I'm wondering if I got a fake. I bought the watch from a poster with good feedback and I got an authentic Sinn box and instructions ( I didn't get the CD and strap changing tool, though).
If it is a fake, it's a darned good one!
Quality control snafu? Fake? Are there an 856's out there without the engraving?
The watch has been great in every other respect.
