“Obsidian” Casio Watch WS1600
Obsidian – Casio ws1600
Full blackout. No light escapes. This stealth-driven build strips everything down to raw minimalism - black shell, matching strap, and dark negative display. It’s built to disappear on the wrist but stay sharp when needed.
Nothing loud. Nothing extra. Just precision in the shadows.
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.
What is Text Removal?
This minimalistic option removes the printed text around the display windows as well as on the faceplate itself. This option includes following text removal:
“10 YEAR BATTERY“
“ILLUMINATOR“
“COUNTDOWN TIMER”
“WR100M”
“ALARM WR CHRONO”
It’s purely cosmetic and gives the watch a sleeker - more refined finish.
Watch Specs:
Digital display, 42.1mm case
Japanese quartz movement
10-year battery life
Water resistant up to 100 meters
LED backlight
Day/date display, 12/24h time
Daily 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.
