Casio’s Crystal G-Shock Is the Most Expensive Ever Made

The most expensive G-Shock ever made is now available to consumers.

Casio has launched a new collection of G-Shock watches called the "Blue Rose Project," featuring blue sapphire crystal. The flagship model, the MRG-D5000, is the most expensive G-Shock ever made at $80,000 and is the first retail G-Shock with an outer case and bezel entirely made of blue sapphire. Only 20 units of this model will be produced. The development was an eight-year project, culminating in a watch that combines G-Shock toughness with Japanese engineering, overcoming the challenge of using a brittle material like sapphire. Previous concepts in 2017 could not meet G-Shock's shock-resistance standards due to the crystal construction. The new MRG-D5000 uses a "Multi-Guard Structure," inspired by Japanese timber framing, to disperse impact across interlocking components. The collection also includes the $9,500 MRG-B5000SA-2 and the $850 GMW-B5000SB-1A. All models maintain G-Shock's signature durability, water resistance, solar power, and radio-controlled timekeeping.

Casio's introduction of an $80,000 fully sapphire G-Shock signals a significant push into the ultra-luxury watch market, challenging established high-end brands. This move leverages advanced engineering to make a notoriously brittle material perform under G-Shock's stringent durability standards, potentially broadening the perception of what a "tough" watch can be. The limited production run indicates a strategy to create extreme exclusivity and desirability, targeting collectors who value unique materials and extreme price points.

This development highlights a growing trend of mainstream technology brands venturing into luxury segments by applying their engineering prowess to premium materials. For consumers, it means more extreme options for high-end timepieces, blurring the lines between rugged functionality and haute horlogerie. Watch enthusiasts should monitor how this strategy impacts pricing and innovation in both the luxury and mainstream watch sectors, particularly regarding material science and shock-resistance engineering.
