Of course you can add the Antarctic to your website, my watch would be honoured!! Unfortunately the crown is not signed but it does look like it’s from a polerouter....?! I’m about to start reading Assault on the unknown by W Sullivan, I don’t know if watches get a mention but I’m going to find out! Antarctic values have definitely gone up in the last 6 months, I was trying to get an Antarctic 2 on eBay.co.uk the other day... it sold for £275, not to me, and to put it in context I paid £42 for my gold Antarctic just over 6 months ago!!
