Casio Launches $80,000 Sapphire G-Shock in Limited Run of 20

Key points

• The MRG-D5000 is priced at $80,000 (11 million JPY) and limited to 20 units worldwide.
• The watch features a blue sapphire outer case and bezel, a Grade 5 titanium inner case, and 24K gold lettering.
• It uses a screwless 'Multi-Guard Structure' inspired by Japanese timber framing to ensure shock resistance.
• The collection includes two other models: the $6,600 MRG-B5000SA-2 and the $770 GMW-B5000SB-1A2.
• The release marks the culmination of a project started by G-Shock creator Kikuo Ibe, who unveiled sapphire prototypes in 2017.

Background

The MR-G line, launched in 1996, represents the high-end tier of G-Shock, combining durability with premium materials and Japanese craftsmanship. In 2017, G-Shock creator Kikuo Ibe unveiled sapphire crystal prototypes at the brand's 35th anniversary celebration, but they were never produced due to shock-resistance concerns. The new MRG-D5000 is part of the MR-G's 30th anniversary program, which also includes the ice-inspired MRG-BF1000EB-1A and the metal-leaf Haruka models.

How outlets are covering it

Hodinkee emphasizes the watch's novelty and the 'high/low humor' of a sapphire-cased G-Shock, noting its 16.45mm thickness and rubber strap. WIRED highlights the price comparison to a Porsche Macan and the 'eight-year project' timeline. Fratello Watches focuses on the technical achievement of the screwless construction and the tribute to Ibe's 'Dream Project.' Revolution Watch contextualizes the release within the MR-G's 30-year history and the broader 30th anniversary program. All sources agree on the $80,000 price and 20-piece limit, but Hodinkee and WIRED note the absence of a sapphire bracelet, while Fratello and Revolution Watch detail the specific materials and craftsmanship involved.

Why it matters

The MRG-D5000 represents a significant milestone for G-Shock, pushing the brand's luxury segment into ultra-high-end territory. It demonstrates Casio's ability to adapt traditional Japanese craftsmanship and advanced engineering to create a shock-resistant watch from a brittle material. The release also signals a continued strategy of offering tiered luxury options, from the $80,000 flagship to the $770 entry-level model, catering to different segments of the collector market.

What to watch

The MRG-D5000 will be sold via lottery in Japan starting in December 2026. The accompanying MRG-B5000SA-2 and GMW-B5000SB-1A2 models are expected to go on sale in November 2026. Casio may explore further sapphire-based designs in the future, potentially including a full sapphire bracelet, as suggested by Hodinkee.
