The Breitling World Time Watch has 4 separate dials working independently. This allows the users to set 4 different time zones and be able to see the time in each without any hassle. The whole watch rotates in both directions so you can move the dial you want to use to a postion that you choose. It's a great watch for a business traveller. You can keep your watch at Home time and change one dial to local time. The silver dial has a delicate cross hatch pattern and also has a compass function. The Bezel is a small decorative 24ct gold band that finishes off the case perfectly. The Silver case with Silver dial is the most sought after of the 80840 series. This watch comes with its original buckle and strap. It also comes with its original box and papers. The box is well travelled and protected the watch very well! I have sold only a couple of these watches over the years as they are so hard to come by and this is the first I've had with original box and papers, so it stands out amongst the few others listed online. I sell mostly vintage watches. Many of them have a Waterproof specification, however, I cannot guarantee that these pieces are waterproof. If you wish to swim or shower in them ensure you your watch checked by a specialist to find out whether the watch is still waterproof. Every watch I have is in fully working order. Again, as they are vintage timepieces they will have some signs of usage. I list the length of bracelet and size of watch and we won't accept return of a watch that does not fit or is smaller or bigger than you thought!
