In 2006, when I was the first time mine A386, its Worth was about € 2.500, and so was till 1 or 2 years ago. During the last year prices increased till double and more and more... I can see most of interesting watches, quality watches, with case and dial in good shape, is increasing nowadays, and I'm not thinking about last Christie's Auctions... I'm talking about professional sellers and private sales... I'd like to know yours thought, and if it is suitable to invest in watches nowadays .
