Hi Reinhold, one of technical folks on here will have more knowledge I'm sure, but I have had trouble like that in the past and it turned out it was something to do with the cal11 movement date wheel teeth wearing down. I would've thought however that the Silverstone was a cal12, which had an updated date wheel. Email Nic at heuer.boy@ntlworld.com, I'm sure he will be able to sort it for you.

Congrats on the watch by the way, I think a Silverstone will be on my 'to buy' list very soon.

Regards

David H
