Bulova is a brand from the United States, but its watch factory is based in Switzerland, founded in 1875 and later acquired by Citizen, and because it is assembled in Switzerland, it is also part of the Swiss watch family. In the 1960 moon landing program, Bulova and Omega were the last two competitors of the watch brand, and although Omega won and became the world's first watch to be worn by an astronaut to land on the moon, all the time and time calculation instruments inside the space shuttle were provided by Bulova. From the 50s to the 70s, Bulova and NASA collaborated on a total of 46 space missions. Bulova watches are not well-known in the domestic watch market, but they are well-known in European and American countries, ranking 9th or 10th among all watch brands in annual sales. Bulova also differs from one collection to another, with models using Citizen movements and models using high-end ETA 7750 movements. Overall, the price of Bulova's better styles is between 2000 and 4000 yuan, and they can strike a good balance between price and aesthetics.
