Casio G-SHOCK GG-B100XMB-1AER Master Of G Mudmaster Black Strap Watch - W17644
Created for professionals operating in the harshest environments, the G-SHOCK Master of G range is engineered with advanced durability at its core. The MUDMASTER pushes this further, purpose-built to perform on land where mud, dust and impact are a constant challenge. It’s a timepiece trusted by rangers and rescue teams working at the limits.
The GG-B100XM-1AER features a silvery stainless-steel bezel with a honed finish, offering excellent scratch resistance and protection from mud and debris, while its subtle matte texture reduces unwanted reflections. The GG-B100XMB-1AER takes a darker approach, with a black ion-plated stainless-steel bezel finished to a mirror sheen that balances durability with refined presence.
At the heart of the GG-B100 MUDMASTER is a high-rigidity carbon case that resists damage and distortion while maintaining exceptional airtightness and shock resistance. A dedicated mud-resistant filter, stainless-steel screw-back and a shock-resistant resin back cover reinforced with glass fibres work together to provide outstanding resistance to dust and mud. Selected case and band components are made from bio-based resin derived from renewable organic resources, helping to reduce environmental impact.
Designed for real-world utility, this watch is equipped with a digital compass, altimeter and barometer, thermometer and step counter. Time correction is simple via the CASIO WATCHES app, which also unlocks features such as Mission Log, automatically combining altitude data from the watch with route data from your smartphone.

Although we do our best to ensure our pictures and descriptions explain our products as clearly as possible, sometimes you may find that when your item arrives it's not quite as you expected, it doesn't fit properly or you may have simply changed your mind.
Don't worry - we have a 30 day change of mind guarantee on all our items.* All you need to do is send the item back in the post (you have to cover these costs) or pop into your local F.Hinds store so they can return the goods on your behalf or arrange for a different size. Products must be returned unused, in a saleable condition and with all original packaging. You are responsible for ensuring the product is not damaged whilst in your care.
*This excludes personalised, bespoke or specially ordered items. This also excludes any ring sizes outside our standard range; I-U for ladies and P-Z+1 for men.
Your chosen store will contact you once your order is ready for collection. In some circumstances we may supply rings in the nearest size available (especially if more than one ring is ordered) which can be adjusted to fit once the item has been paid for and the branch have confirmed the finger size. Items that need to be specially ordered are not available for this service and must be paid for in full before ordering. The store will hold your order for 1 week and then it will be returned to stock.
Please note the expected dispatch dates stated for each product as this indicates how long it will take us to dispatch your order. Express Delivery is offered for most items but this does not mean the item(s) will be dispatched any sooner than the expected dispatch date. Orders for multiple items will be dispatched together and are therefore collectively subject to the longest dispatch time stated. Parcels may be sent via courier which is a next working day service and requires a signature on delivery.
We offer international delivery within the EU and EAA on jewellery and most watches; sorry we are unable to dispatch heavy or bulky items and some selected ranges outside of the UK. Please be aware that local taxes and fees may be applied and the customer is responsible for paying these. International Delivery is a minimum of 3-5 working days from the expected dispatch date and may be considerably longer for more remote or distant locations.
