This article is your deep dive into why you should mod the W-800H, the essential mods you need to know, and a step-by-step guide to executing them. Before we break out the screwdrivers and bezel inserts, we must answer: Why this model? Casio produces dozens of square and rectangular digitals. Why mod the W-800H? 1. The "F91-W" Problem (Size) The legendary F-91W is a masterpiece, but it looks like a toy on a 7.5-inch wrist. The W-800H measures approximately 44mm wide and 48mm lug-to-lug. It wears like a proper sports watch. When you add a chunky bezel or a nylon strap, it commands wrist presence. 2. The 10-Year Battery & 100M WR Most mods start with the case. Because the W-800H has a screw-down case back (unlike the F-91W’s friction fit) and 100M water resistance, you can actually take a modded watch swimming. The CR2025 battery lasts a decade, meaning you aren't opening the case every year. 3. The "Dual Time" Function The module (3524 or 3298) features a dedicated dual-time zone. This makes the W-800H a perfect base for a "GMT" style mod—a poor man’s Explorer II. 4. Affordability You can ruin a W-800H and be out $18. You cannot say the same about a G-Shock. This low risk encourages experimentation. Part 2: The Anatomy of a W-800H Mod When the community talks about a "Casio W-800H mod," they are rarely talking about changing the module.
