Prominent sword-style hour and minute hands are finished in matching gold tone with luminous coatings, accompanied by a slender central sweep seconds hand for precise time tracking. The chronograph layout provides instant timing feedback: a 1\/10-second stopwatch register sits at 12 o'clock, a 60-minute stopwatch register is positioned at 9 o'clock, and the continuous stopwatch seconds register rests at 6 o'clock. Positioned neatly at 3 o'clock is a framed date calendar aperture. \u003cspan class=\"citation-541 citation-end-541\"\u003eFraming the dial is an angular, multi-faceted fixed stainless steel bezel accented with gold ion-plated segments and an engraved tachymeter-style timing ring that enhances the watch’s muscular, athletic stance.\u003csup class=\"superscript\" data-turn-source-index=\"4\"\u003e\u003c!----\u003e\u003c\/sup\u003e\u003c\/span\u003e \u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003eBeneath its tailored exterior, the watch is powered by Casio’s proven in-house Module 5345 Japanese quartz chronograph movement, engineered and manufactured to deliver dependable timing under rigorous daily conditions. \u003cspan class=\"citation-540\"\u003eBuilt for precision athletic timing, the caliber features a dedicated \u003c\/span\u003e\u003cspan class=\"citation-540\"\u003e1\/10-second stopwatch chronograph\u003c\/span\u003e\u003cspan class=\"citation-540\"\u003e capable of measuring elapsed time, split time, and 1st-2nd place times up to \u003c\/span\u003e\u003cspan class=\"citation-540\"\u003e59 minutes and 59.9 seconds\u003c\/span\u003e\u003cspan class=\"citation-540 citation-end-540\"\u003e.\u003csup class=\"superscript\" data-turn-source-index=\"5\"\u003e\u003c!----\u003e\u003c\/sup\u003e\u003c\/span\u003e Operating at an oscillation frequency of 32,768 Hz, the movement delivers a factory-rated precision tolerance of ±20 seconds per month. \u003cspan class=\"citation-539\"\u003ePowered by an efficient silver oxide battery cell (SR920SW), the movement provides an approximate battery service life of \u003c\/span\u003e\u003cspan class=\"citation-539\"\u003e2 years\u003c\/span\u003e\u003cspan class=\"citation-539 citation-end-539\"\u003e, ensuring consistent, grab-and-go performance.\u003csup class=\"superscript\" data-turn-source-index=\"6\"\u003e\u003c!----\u003e\u003c\/sup\u003e\u003c\/span\u003e \u003cspan class=\"citation-538 citation-end-538\"\u003eThe movement incorporates an instantaneous date-correction mechanism, an independently driven 1\/10-second timing needle, and traditional dual-pusher chronograph operation flanking the central setting crown.\u003csup class=\"superscript\" data-turn-source-index=\"7\"\u003e\u003c!----\u003e\u003c\/sup\u003e\u003c\/span\u003e \u003cspan class=\"citation-537\"\u003eThe case is engineered with substantial, wrist-commanding sports proportions, measuring an official \u003c\/span\u003e\u003cspan class=\"citation-537\"\u003e49.5mm in case diameter\u003c\/span\u003e\u003cspan class=\"citation-537\"\u003e (54.1mm from top lug tip to bottom lug tip) with a case profile thickness of \u003c\/span\u003e\u003cspan class=\"citation-537\"\u003e11.7mm\u003c\/span\u003e\u003cspan class=\"citation-537\"\u003e, and a standard \u003c\/span\u003e\u003cspan class=\"citation-537\"\u003e22mm lug width\u003c\/span\u003e\u003cspan class=\"citation-537 citation-end-537\"\u003e.\u003csup class=\"superscript\" data-turn-source-index=\"8\"\u003e\u003c!----\u003e\u003c\/sup\u003e\u003c\/span\u003e \u003cspan class=\"citation-536\"\u003eWeighing a reassuring \u003c\/span\u003e\u003cspan class=\"citation-536\"\u003e185.0 grams\u003c\/span\u003e\u003cspan class=\"citation-536 citation-end-536\"\u003e, the watch conveys an authoritative, substantial heft on the wrist that reflects its solid metal build quality.\u003csup class=\"superscript\" data-turn-source-index=\"9\"\u003e\u003c!----\u003e\u003c\/sup\u003e\u003c\/span\u003e The solid stainless steel case architecture combines satin-brushed lug hoods with mirror-polished flanks and selective yellow gold ion plating across the bezel, crown, and pushers.
