Accutron watches are made by the Bulova watch company. Originally designed in the 1950s for NASA, Accutron's state-of-the-art timekeeping mechanism is accurate to within two seconds a year. The success of the Accutron electronics was phenomenal enough that the Bulova Accutron division decided to manufacture a line of consumer Accutron watches with the Accutron mechanism. These were the Accutron Spaceview watches. Thus, the first automatic electronic watches for consumers were born. With over 50 years of perfecting the watch manufacturing process, Accutron watches have become the brand the world trusts. All Accutron watches are made with solid stainless steel cases for durability and elegance, and they include the most advanced Swiss quartz movements available in the world today. Bulova's Accutron watches also come with stainless steel link bracelets, and many Accutron watches have a hidden clasp that makes the bracelet appear virtually seamless. The crystals of all Accutron watches are scratch-resistant sapphire or mineral glass crystals, and Bulova's Accutron watches are water resistant in the range of 20 meters to 200 meters.
