The orange accents reference the high-vis colour coding used on heavy equipment, construction machinery, and emergency gear — a visual cue that reinforces the Mudmaster's identity as a watch built for harsh work environments.\u003c\/p\u003e\n    \u003cp\u003eModule 5744 and every specification are identical to the -1A: Quad Sensor (digital compass with hand indication of north, altimeter up to 10,000 metres with auto logging, barometer with pressure tendency alarm, thermometer, and step counter via 3-axis accelerometer), Bluetooth smartphone link with Mission Log, Carbon Core Guard with carbon fiber-reinforced bio-based resin case, mud-resistant sealed buttons, three-layer carbon fiber bezel, stainless steel panel back, double LED Super Illuminator, world time across 38 time zones, sunrise\/sunset display, Neobrite lume, and 200-metre water resistance. 55.4 × 51.3 × 19.4 mm, 93 grams.

WHY YOU'LL LOVE IT --\u003e\n  \u003cdiv class=\"cc-section\"\u003e\n    \u003ch2\u003eWhy You'll Love It\u003c\/h2\u003e\n    \u003cul class=\"cc-benefits\"\u003e\n      \u003cli\u003eThe orange accents on the black carbon case are the visual difference between the -1A9 and the all-black -1A — and they serve a practical purpose beyond aesthetics. High-vis orange is the colour language of heavy machinery, emergency equipment, and field gear. On the Mudmaster, it makes the dial markings and hands easier to read at a glance in low-light or busy conditions, and it makes the watch easier to spot if you set it down on a worksite or trail.\u003c\/li\u003e\n      \u003cli\u003eThe Quad Sensor system delivers four environmental readings from your wrist: compass bearing with analog hand indication of north, altimeter up to 10,000 metres with automatic data logging, barometer with a pressure tendency alarm that warns of incoming weather shifts, thermometer, and step counter. Each sensor provides data you can act on in real time — navigation, elevation, weather prediction, temperature, activity tracking.\u003c\/li\u003e\n      \u003cli\u003eMud resistance is engineered into the buttons — gaskets and filters prevent dust, sand, and mud from entering the case. The carbon fiber-reinforced resin case and Carbon Core Guard structure resist warping and absorb shocks. The stainless steel panel back and glass-fiber resin back cover maintain the seal under impact. This is a watch designed for construction, forestry, disaster relief, and any environment where fine particles are unavoidable.\u003c\/li\u003e\n      \u003cli\u003eThe Mission Log function records altitude data from the watch's altimeter and route data from your phone's GPS, building a combined log in the CASIO WATCHES app. Over time, you accumulate a mapped history of your outdoor activities with elevation profiles — useful for hikers, trail runners, and field workers tracking their routes.\u003c\/li\u003e\n      \u003cli\u003eThe barometric pressure tendency alarm buzzes when atmospheric pressure changes significantly — advance warning of an incoming storm or weather shift before you can see it. The pressure graph shows the last 20 or 56 hours of atmospheric data.\u003c\/li\u003e\n      \u003cli\u003eBio-based resin for key case and band components reduces environmental impact. At 93 grams with a carbon fiber-reinforced structure, the Mudmaster is lighter than you'd expect for a watch this tough — the carbon construction carries the strength of a heavier build at lower weight.\u003c\/li\u003e\n    \u003c\/ul\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- 4.
