Accompanied by IWC Extract from the Archives dated 8 June 2007 confirming the sale of the present watch to Weinstabl on 18 August 1942.
In the late 1930s, IWC received a rather unusual order from a customer in Portugal who requested a wristwatch with the same size and accuracy of a pocket watch. To comply with his request, IWC chose their at the time slimmest and most reliable calibre 74 movement and cased it in stainless steel. This revolutionary model immediately became a legend and classic amongst collectors and was also the obvious choice to celebrate the company's 125th anniversary in 1993 with the launch of a limited edition of total 1000 examples.
The present watch is preserved in beautiful, original condition, the rarity enhanced by the period Gay Frères bracelet.
