“Raven” Casio F91W Watch
“Raven” – Casio F91W
Full negative display with light digits. Ultra-clean and completely stealth. No color, no noise—just pure function.
What is Negative Display?
The Negative Display option swaps out the standard reflective film inside the screen for a specialized polarized layer. This flips the contrast - giving you light-colored digits on a dark background instead of the usual black-on-silver look. It’s purely visual - no changes to how the watch functions. Just a cleaner, stealthier look to make your build stand out.
Watch Specs:
Digital display, 35.2mm case
Japanese quartz movement
7-year battery life
Water resistant up to 200 meters
LED backlight
Day/date display, 12/24h time
5 alarms, stopwatch, countdown timer, world time
Notes:
Photos are taken under bright lighting - colors may look slightly darker in person or at certain angles. Since each watch is modified by hand, small dust specks or light marks may be visible. These are normal and do not affect performance.
The original Casio warranty does not apply due to the modification. If you have any questions or need support, feel free to reach out.
