The single automatic watch winder comes equipped with two cushion options to cater to different wrist sizes and preferences. The Standard cushion is ideal for watches with a strap circumference ranging from 19cm to 24cm, accommodating the majority of users. Alternatively, the Flex cushion is perfect for smaller wrist sizes, fitting straps from 14cm to 20cm. This choice allows for a more tailored fit, ensuring that watches are securely held and optimally maintained while in the winder.
