Sellita SW510 BH b Description

The Sellita SW510 BH b is a modern, manual-wind, Swiss-made chronograph caliber based on the Valjoux 7750/7753 architecture. As part of Sellita’s “clone” series, it provides a vital alternative for brands. “BH” denotes the tri-compax layout (3-6-9), and “b” signifies it has no date function. It is known for its reliability and an extended power reserve, making it a popular choice for contemporary manual-wind chronographs.
