1945 Bulova American Eagle
Nice band but I think it's likely early 60's if it's a "twist-o-flex" style. If it's a scissor style, it's period. If anyone is interested:
"In the 1950s, Speidel invested heavily in the development of automatic equipment to produce a bracelet similar to the German Fixo-Flex watchband. A German manufacturer had sent the first version of the Fixo-Flex to Paul Levinger who had worked out a license contract with the inventor, Karl E. Stiegle. In 1956, the first automatically produced bracelet under this patent was introduced as a test under the Kingsway brand. Speidel introduced the Twist-O-Flex in 1959, after licensing the technology from its German inventor, Karl E. Stiegele.
The "Twist-O-Flex" consists of various styles of metal bracelet watchbands; the special link design creates a single-component, stretchable bracelet (also called an "expansion bracelet" and once known as a "scissor-link" bracelet).
In 1956 the first automatically produced bracelet under patent was introduced. By 1959 the company officially introduced the new watchband as the “Twist-O-Flex”. This watch band was and is considered light years ahead of any other watchband products, was a sales phenomenon and was the fashion statement of its time.
Twist-O-Flex introduced in 1961 and the Youth Twist-O-Flex in 1963. The Twist-O-Flex was popularly called the "tank track" due to its resemblance to the tread of a tank when laid flat. "
