I have seen a few of these crop up over recent weeks on various sites and indeed a very nice looking 510.403 sold last week for circa £1400 on Ebay. I'm sure that they have been discussed before but:
Are they really Silverstones just without the name? ( I know that some of them are marked "Silverstone" on the dial but are not one of the three "true" Silverstones)
Is £1400 a reasonable sort of price or could/should they be more?
Either way, I believe that they are good looking watches and even if they aren't Silverstones they have a value and an attraction all of their own. Am I alone or does anyone else have similar thoughts?
