Dear Bidder, For your attention, please be aware you are bidding on a “marriage watch”. This is composed of a pocket watch movement and a NEW custom-made (or pocket watch) case converted into a wristwatch. Please consider this before bidding so as to avoid any misunderstanding. In addition, please note that all the main components of the watch – the movement, dial and hands – are original and come from an authentic IWC Schaffhausen pocket watch. Due to the conversion so that the watch can be worn on the wrist, only the case elements are new, carefully made and fitted to match the original pocket watch parts. The result is a beautiful wristwatch with an antique IWC movement, which makes it a very special piece – all the more so because you can admire the work of the movement through the transparent display back. Thank you. You save 369,00 EUR right away The service and identification document is included in the price.
