An intermediate portion of the wheel guard, between the first and second end portions thereof, extends through a central opening of the calendar display wheel to mount the display wheel for rotation. The first end of portion of the wheel guard has the maximum diameter of the wheel guard, and the end face of the first end portion of the wheel guard abuts a dial plate of the calendar timepiece so that the first end portion of the wheel guard maintains the dial plate spaced from the calendar display wheel.
