Watch face for Casio F-84W, F-91W, A158W, A159W, A163W, A164W, A171W, W-31, and W-78
Inversion of the standard Module 593 display.
The face mirrors the standard clock layout while reversing every LCD segment, including the alarm, 12/24-hour, PM, and low-battery indicators. It supports the classic and custom Sensor Watch LCDs, checks the battery once per active day, and blanks seconds in low-energy mode.
The hourly signal remains owned by Second Movement's standard Clock face. This avoids multiple face advisories sounding the same chime at the top of the hour. When this is not the primary face, Second Movement returns to face 0 after the configured inactivity timeout.
