This watch has travelled the seas to end in Canada from the UK, only one example can be found online and changed hands from Fellows auctioneers to a dealer in UK to a customer of mine and then to me. This rarity is well preserved overall and still looks the part for a 60 years old watch. The Crown/Escape valve makes this watch very special and rare in design, with its brevet number on the back.
