The MTG-B4000 marks a genuine first in G-Shock history: a structural frame co-developed by human designers and generative artificial intelligence. AI-driven stress simulation optimised the Dual Core Guard structure, integrating laminated carbon and glass fibre sheets with stainless steel into a dimensional, multi-layered frame of exceptional structural complexity.\u003c\/p\u003e\n\u003cp\u003eTriple G Resist protection simultaneously guards against shock, centrifugal force, and vibration to G-Shock's most exacting standards. The dual-layer stainless steel bezel is finished with separately applied hairline and mirror polishing, then ion-plated in black for a dark, cohesive look that carries consistently across the case, frame, and band. The multi-layer dial is the precision work of Yamagata Casio, protected by a sapphire crystal with anti-reflective coating for exceptional clarity at every angle.\u003c\/p\u003e\n\u003cp\u003eThe dimensional case back is formed using metal injection moulding (MIM), enabling structural complexity impossible through conventional machining. Timekeeping is managed through Tough Solar charging, Multiband 6 radio control, and Bluetooth connectivity via the Casio Watches app — delivering automatic time correction and access to approximately 300 world time cities. At 178 grams, the MTGB4000BD-1A wears with authority. With 200-metre water resistance, it is built to perform wherever it is taken.\u003c\/p\u003e","brand":"Casio","offers":[{"title":"Default Title","offer_id":48530826133696,"sku":"1NMTG027","price":2499.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0533\/3847\/2640\/files\/MTGB4000BD-1A.jpg?v=1782895362","url":"https:\/\/www.wallacebishop.com.au\/products\/1nmtg027-casio-g-shock-m-tg-solar-mens-watch-mtgb4000bd-1a","provider":"Wallace Bishop","version":"1.0","type":"link"}
