For sale: Seiko 6117-6400 World Timer from 1970 (waterproof caseback + error bezel) Condition: Very good with the exception of the mark/patina in the middle of the dial. The dial (and bezel) maintain great legibility and had no fading on the lettering which is pretty rare. The watch has some slight scratches from normal use but is in otherwise superb condition especially considering it's age(55+ yr old). Watch is winding, keeping good time and all functions like date change and rotating the bezel operate without any issues. Details: The watch dates back to august 1970 and because of this still has 'WATERPROOF' on the caseback, watches from 1971 and later have 'water resist(ant)' due to changes in (US) regulations at the time. That's not the only historical thing about this watch, the watch has the world timer bezel known as the 'error bezel' , an intended error tough, London and GMT are placed besides eachother instead of on top of eachother. This is due to an experiment with British standard time that lasted only a few years. Includes: Watch only (+ leather and optional rubber strap) Price: $495 Payment: PayPal F&F or G&S for anyone with at least 1 transaction/reference on watchexchange (+4,3% fee for the buyer).
