Concept: The Perfected Icon with a Signature Touch

This special edition is based on the GW-M5610U, which is the technical evolution of the classic “Square.” The collaboration with Tamio Okuda is often characterized by a “Heavy Duty” / Military aesthetic: industrial typography, sober colors (greens, blacks, grays), and personalized details on the strap and back cover. It is the perfect fusion of G-Shock history and Japanese pop culture.

⚙️ The Technological Leap: Module 3495 (The “U” is the key)

Unlike the old 5610 models, this “U” version includes improvements that fans have been clamoring for, making it much more usable on a daily basis:

1. LED light (Super Illuminator): Replaces the old EL (green) light. It is now a powerful white light with a fade-out feature.
2. Configurable Date: Finally! Allows you to change the date format from “Month-Day” to “Day-Month” (European style).
3. Day of the week in Spanish: The module allows you to set the language of the day of the week (Spanish, English, French, German, Italian, Russian).
4. Current time in other modes: You can see the current time while using the stopwatch or timer (something the previous model did not do).

🔋 “Set and Forget” technology (Set and forget)

This watch is designed to be maintenance-free for years:

• Tough Solar: Charges from any light source (sun or artificial). No need to change the battery.
• Multiband 6: Connects by radio frequency to 6 atomic towers around the world (including Germany for Europe) every night to calibrate the time to the exact second. Always on time.

💎 Exclusive Details (Okuda Factor)

• Visual Customization: These editions usually include Tamio Okuda's signature or his “OT” logo on the dial, the strap loop, or engraved on the back cover.
• Special Packaging: It usually comes in a box or tin designed specifically for the collaboration, which increases its resale value.

Look & Feel: Unlike the standard model, this one usually has a more pronounced matte finish or color combinations on the display (sometimes negative or with gold/yellow tints depending on the specific edition of the year).
