A recently granted patent (Publication Number: US11880168B2) discloses a unique timepiece design featuring a crown with a shaft part connected to the movement within the outer case. The crown includes an operation part that enables rotation in a circumferential direction and an engagement part that restricts axial movement when engaged with an engagement member connected to the outer case. The engagement part, a cylindrical member with a specific structure, allows for engagement with the engagement member, ensuring proper functionality of the timepiece.
The patent claims further detail variations in the design, such as the integration or separation of the engagement member from the outer case, the method of engagement between the engagement part and the engagement member (e.g., screwing), and the specific structures facilitating the rotatable holding of the operation part. Additionally, the crown's functionality includes winding the mainspring of the movement when engaged with the engagement member and rotating a hand connected to the movement when the engagement is released and the crown is pulled out. This innovative timepiece design aims to enhance the overall user experience and functionality of the watch while maintaining a sleek and efficient design.
