brace or bridle

Is a thin, curved metal piece used to support and secure the balance wheel and its associated parts. It is typically made of a durable and corrosion-resistant material such as steel or specialized watch alloys. The shape of the brace or bridle is designed to ensure proper alignment and stability of the balance wheel, allowing it to oscillate freely within its designated range. The shape and materials of the brace or bridle may vary in watches depending on the watch movement and design.
