The design uses a metal bezel in light yellow gold ion plating with key metal components accented in brown ion plating, paired with a dark brown resin band. The GG-B100XMH-5A is the Mudmaster in the series, alongside the GR-B300H-5A and the GW-9500MH-5.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cc-faq-item\"\u003e\n\u003cp class=\"cc-faq-q\"\u003eWill the gold finish wear off?\u003c\/p\u003e\n\u003cp class=\"cc-faq-a\"\u003eIon plating bonds the finish to the steel at a molecular level rather than laying a coating on the surface, which makes it considerably more durable than conventional plating. It will still show wear over years of heavy contact with abrasive surfaces.

A 3-axis accelerometer adds step counting on top.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cc-faq-item\"\u003e\n\u003cp class=\"cc-faq-q\"\u003eWhat does mud resistant mean, and how is it different from water resistant?\u003c\/p\u003e\n\u003cp class=\"cc-faq-a\"\u003eWater resistance keeps liquid out. Mud resistance keeps solids out — grit, sand, slurry and debris that can work into button shafts and case seams where water alone would drain away. This model uses a dedicated filter against mud, a sealed carbon fibre-reinforced case and a back cover of shock-resistant resin strengthened with glass fibre. Both ratings apply here: mud resistant and 200 metres.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cc-faq-item\"\u003e\n\u003cp class=\"cc-faq-q\"\u003eIs this watch solar powered?\u003c\/p\u003e\n\u003cp class=\"cc-faq-a\"\u003eNo. The GG-B100XMH-5ADR runs on a CR2025 battery with a life of approximately two years. It corrects its own time over Bluetooth rather than by solar or radio signal, so there is no charging behaviour to manage — just a battery change roughly every two years, which any City Chain outlet can handle.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cc-faq-item\"\u003e\n\u003cp class=\"cc-faq-q\"\u003eHow does this compare to the resin-bezel GG-B100X models?\u003c\/p\u003e\n\u003cp class=\"cc-faq-a\"\u003eModule, sensors, construction and the 200-metre rating are identical. The difference is the bezel: the XMH uses a stainless steel bezel with gold ion plating where the GG-B100X-1A, 1A3 and 1A9 use a carbon fibre bezel in resin. That takes the weight from 93 grams to 104 grams and changes the register from equipment to something with more presence.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cc-faq-item\"\u003e\n\u003cp class=\"cc-faq-q\"\u003eCan I swim or dive with it?\u003c\/p\u003e\n\u003cp class=\"cc-faq-a\"\u003eYou can swim and snorkel with it. 200-metre (20 BAR) water resistance covers swimming, surfing and recreational water sports. It is not rated for saturation diving or use with helium-based gas mixtures.

At 104 grams it stays manageable through a full day, but the 51.3mm width will overhang on wrists under about 16cm. The band fits 145mm to 215mm.
