Thirty years after the debut of its most premium line, G-SHOCK is marking the anniversary of MR-G with a timepiece that brings Japanese craftsmanship, advanced materials and modern watchmaking technology together.
The new MRG-B2100HR is limited to just 800 pieces worldwide, with its design drawing inspiration from kigumi, the traditional Japanese woodworking technique that creates intricate structures through interlocking wooden joints without nails or metal fittings.
For the anniversary model, that idea of precision and structure is translated into metal. At the centre of the watch is a dimensional latticework dial finished with platinum leaf, created in collaboration with metal leaf artist Hiroto Rakusho.
The use of platinum leaf gives every watch a subtly individual character. Rather than producing a perfectly uniform surface, powdered platinum leaf creates variations in depth and texture, allowing the material itself to become part of the visual identity of each piece.
The concept extends from the dial to the overall design through the theme of haruka, referring to a sense of eternity. It is an appropriate idea for an anniversary timepiece built around the meeting of traditional Japanese techniques and contemporary engineering.
The MRG-B2100HR is based on the shock-resistant MRG-B2100, retaining its distinctive octagonal bezel while introducing a considerably more elaborate treatment across the case and bracelet.
One of its most striking details is found in the way colour is created. Rather than relying on conventional coatings, the bezel and bracelet feature metal leaf-inspired textures produced using structural color technology. An ultrashort-pulse laser is used to create microscopic structures that interact with light, producing colours that shift depending on the viewing angle.
The effect takes inspiration from the iridescent colours found in nature, such as those seen on butterfly wings and certain minerals, while giving the watch a distinctly contemporary finish.
The construction itself is equally meticulous. The bezel is made from 27 individual components, each polished before being assembled into the finished structure. This multi-part approach allows the complex form to be produced while maintaining the precision and durability expected from the MR-G line.
Material selection further reinforces that balance between refinement and toughness. The bezel uses COBARION, a super-hard cobalt-chromium alloy known for its polished finish, while the bracelet is constructed from DAT55, another high-performance alloy developed for demanding applications.
Together, the materials give the MRG-B2100HR a distinctly metallic presence without losing the durability that has defined G-SHOCK since its beginnings.
What makes the anniversary model particularly interesting, however, is the dialogue between the traditional and the technical. Platinum leaf is an artisanal material with centuries of cultural associations in Japan, while structural colour created through ultrashort-pulse laser processing represents the precision of contemporary manufacturing.
The collaboration with Rakusho reinforces that connection. His original metal leaf artwork was developed alongside the watch, giving the MRG-B2100HR a visual language that moves between traditional craftsmanship and modern industrial design.
That approach also reflects the broader evolution of MR-G. Since its introduction in 1996, the line has represented G-SHOCKâs exploration of premium materials, Japanese craftsmanship and increasingly sophisticated construction, while maintaining the fundamental shock resistance that defines the brand.
The MRG-B2100HR turns that history into a highly limited anniversary statement. Its latticework structure, platinum leaf dial, colour-shifting surfaces and multi-component construction are not simply decorative additions; they demonstrate how traditional Japanese ideas can be reinterpreted through modern technology.
With only 800 pieces available worldwide, the 30th-anniversary MR-G is ultimately a meeting of two kinds of precision – the patience of hand-applied craft and the microscopic accuracy of advanced manufacturing brought together in a watch designed to express the idea of time that continues beyond the present.
