Description
The G-SHOCK Master of G Mudmaster GGB100X-1A9 is a rugged, mission-ready watch engineered for extreme environments. Featuring a black carbon-reinforced resin case with a black dial, digital display window and a high-visibility orange resin strap, it delivers uncompromising toughness with bold outdoor style.

Built for professionals who operate in harsh, debris-filled and muddy terrain, this Mudmaster uses carbon materials in the case and bezel for exceptional strength, impact resistance and airtight construction. A dedicated mud-resistant structure with a stainless-steel case back and reinforced components helps protect against dust and dirt, while eco-conscious biomass plastics are used in key resin parts to reduce environmental impact.

Functionally advanced, it measures direction, altitude, barometric pressure, temperature and steps, and connects via Bluetooth® to a smartphone for automatic time correction and Mission Log tracking. With shock and mud resistance, a Super Illuminator double LED light, analogue and digital timekeeping, and up to two years of battery life, the GGB100X-1A9 is a dependable tool designed to support precise decisions in the toughest conditions.

It's not simple to find a jeweller you can genuinely rely on. When purchasing a special piece like a diamond ring or gold pendant, it's natural that you'll want to ensure that every dollar is well spent and every promise is real. Far too often, grand promises fail to deliver because the pricing and workmanship don't always align. That's why peace of mind matters as much as the sparkle. Shiels has been known for combining affordability with value since 1945, delivering gorgeous pieces people can trust and depend on. You can always be certain about who you're purchasing from and exactly what you're spending, with no surprises or hidden fees. Every item is sourced by in-house jewellery hunters who work hard to bring you the latest and most stunningly crafted designs you won't find elsewhere. Whether you're selecting your first diamond or expanding your collection with something special, we make sure your experience stays transparent, fair and straightforward. With Australia's biggest range of jewellery at unbeatable prices, we've earned our reputation by helping people find designs they love, like G-Shock Master of G Mudmaster GGB100X-1A9. We're committed to making beautiful jewellery accessible, offering high-quality designs that look lovely without high price tags.

For every memorable occasion, a matching piece of jewellery adds meaningful value. Make birthdays extra special with colourful gemstones or a charm bracelet that reflects the personality of the recipient. For baptisms or christenings, timeless pearls or elegant gold lockets are keepsakes that can be passed down through generations. Marking new beginnings, graduations are well represented by watches or initial jewellery featuring bold, modern styles that symbolise achievement and progress. Every piece in our collection is chosen with care to offer longevity and a touch of sentiment for life's milestones. However, it's not only the big occasions that deserve attention, as you can get rings, earrings, necklaces, pendants, chains, bracelets, bangles or anklets to treat yourself. We even have a selection of 1-, 2- and 3-carat natural and lab-grown diamonds, with every design having the potential to turn an ordinary day into a memory worth remembering. Plus, if you're looking for designs with colourful gemstones, you can explore our pieces with aquamarine, emerald, ruby, amethyst or opal. No matter if you're looking for 9ct Yellow Gold 0.15 Carat Diamond Ring with 25 Diamonds, 9ct Yellow Gold Cubic Zirconia Line Stud Earrings or Luminesce Lab Grown 1/2 Carat Diamond and Natural Blue Topaz Bolo Bracelet in Sterling Silver, you'll find a wide array of jewellery and watches that celebrate individuality and add warmth to life's special moments.
