Casio’s MRG-D5000 Blue Sapphire takes the familiar square G-SHOCK silhouette into the premium MR-G collection with a bezel made entirely from blue sapphire crystal. Announced on 1 October 2026, the watch pairs that unusual material with a screwless, multi-component construction that Casio says is designed to preserve shock resistance. The company plans a December 2026 release and says only 20 watches will be available worldwide.
What is the MRG-D5000 Blue Sapphire?
The MRG-D5000 is a limited-edition model in Casio’s MR-G collection, the brand’s premium G-SHOCK line. Its central visual change is the bezel: Casio describes it as rendered entirely in blue sapphire crystal, set around the recognizable square form associated with G-SHOCK. The announcement coincides with the MR-G collection’s 30th anniversary in 2026; the anniversary refers to the collection, not to this specific watch.
Casio’s launch announcement calls out a “screwless, multi-component structure” alongside the sapphire bezel. This is a construction intended to accommodate sapphire components in a shock-resistant watch, rather than simply a conventional metal bezel with a blue finish. The shock-resistance claim is Casio’s specification, not an independently verified test result. Casio’s 1 October 2026 announcement introduces the model and its stated construction.
How the sapphire design changes the square G-SHOCK
Blue sapphire bezel
The bezel’s all-sapphire construction is the defining feature. It gives the familiar square profile a different material character from the more conventional metal or resin treatments associated with the shape, while retaining the watch’s G-SHOCK identity. The source material establishes the bezel as sapphire crystal; it does not provide a basis for claims about scratch performance, clarity under particular lighting, or how the watch looks in person.

- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
Screwless, multi-component build
Casio says it developed a screwless multi-component structure for this design. That detail matters because sapphire is being incorporated into a watch whose listed specification includes shock resistance. Casio presents the structure as part of the engineering solution, but published launch information does not give independent impact-test results or a detailed account of the assembly method.
T3’s report, published on 1 October 2026, describes the project as an eight-year engineering effort and says Casio had shown a sapphire concept in 2018 that did not then meet shock-resistance requirements. That chronology is secondary reporting; Casio’s launch release does not independently document it. T3’s coverage provides that development context.

How limited is the edition, and when is it due?
Casio says the worldwide edition is limited to 20 watches. The US product page describes casebacks numbered from 1/20 through 20/20, underscoring that this is a small numbered run rather than a broadly stocked release. The international product page gives December 2026 as the planned release timing.
In the United States, Casio’s page invites visitors to register for an opportunity, but says availability, eligibility, selection and the purchase window are subject to final official terms. Registration should not be treated as a guarantee of the chance to buy. Casio’s US page is the place to check those conditions: MRG-D5000 at Casio US.

Price and availability
The official Casio pages cited here do not establish a retail price or general marketplace stock. With only 20 pieces announced worldwide and US access conditional on final terms, the available information does not support treating the MRG-D5000 as an ordinary retail or Amazon release. Check Casio’s local product page for current regional terms; availability may differ by market.
Who is this watch for?
The MRG-D5000 is most notable for bringing an all-blue-sapphire bezel and a specialized construction approach to a square G-SHOCK, within a very small edition. Its listed 200-meter water resistance, solar charging and radio-controlled time adjustment are useful specifications, but the evidence available for this announcement does not establish independent performance testing or a confirmed price. For prospective buyers, the first practical question is whether Casio’s regional process offers a purchase opportunity at all.
