Description
The Casio G-Shock GM-114GEM-1A9DR (cataloged within the elite G-Shock 40th Anniversary Adventurer’s Stone Collection, and recognized in India under model code G1346) is a striking, high-performance Japanese quartz analog-digital streetwear timepiece. Created to celebrate the 40th Anniversary of G-Shock (1983–2023), this model pays direct homage to calcite—the mineral ancient seafarers and adventurers used as a optical compass to navigate by the sun's position under cloudy skies. Built upon the bold architecture of the metal-covered 110 series, it combines industrial heft with mineral-inspired artistry. Across international collector circles, high-end streetwear communities, and G-Shock forums, it has earned community nicknames like the "Calcite 114", "Adventurer's Stone Gold", "Black and Gold IP 110", or simply the "G1346 Anniversary". It earns these names for its forged, two-tone ion-plated bezel, gold vapor-deposited dial, hot-stamped textured resin band, and exclusive 40th-anniversary caseback engraving. It unites a shock-resistant and magnetic-resistant inner case enveloped in a textured stainless steel bezel measuring 48.8mm in width (51.9mm lug-to-lug) with a multi-layered analog-digital face, mineral crystal glass, an in-house Japanese multi-function quartz engine, and an integrated black resin strap. Weighing a substantial 99.0 grams, it is meticulously calibrated for watch collectors, streetwear enthusiasts, and modern explorers seeking an indestructible statement piece with deep historical inspiration.
The defining visual centerpiece of this GM-114GEM-1A9DR reference is its Forged Calcite Bezel and Two-Tone Ion Plating. Casio engineers utilized specialized forging dies to press a rough, mineral-inspired rugged texture across the entire stainless steel bezel face. This uneven surface is treated with a complex two-tone Gold and Black Ion Plating (IP) to represent calcite's base ore and its multifaceted light reflection. The dial features a brilliant gold vapor deposition finish that contrasts sharply against the dark case elements. When the high-brightness white Super Illuminator LED light is engaged, it illuminates the analog-digital readouts with exceptional clarity in total darkness. Turning the watch over reveals a solid stainless steel screw-lock caseback deeply engraved with the official G-Shock 40th Anniversary logo designed by legendary street artist Eric Haze, while the black resin band loop is laser-engraved with four stars symbolizing 40 years of toughness.
Beneath its artistic exterior, the watch is driven by Casio’s heavy-duty in-house Japanese analog-digital quartz engine. Engineered to withstand demanding physical activity, the module is suspended inside a hollow-case shock-resistant resin structure that cushions sensitive internal electronics against severe drops and vibrational impacts. To combat environmental interference, the module is shielded with a JIS Class 1 Magnetic Resistance rating, ensuring the analog hands remain perfectly synchronized near magnetic fields. Operating at a standard quartz frequency of 32,768 Hz, the movement delivers a factory-rated precision tolerance of ±15 seconds per month. Powered by two SR927W silver oxide batteries, the watch provides dependable autonomous operation for approximately 3 years.
The watch packs a comprehensive suite of practical digital timekeeping tools. The World Time complication covers 48 major global cities (31 time zones) plus Coordinated Universal Time (UTC), complete with daylight saving toggling and home/world time swapping. Athletic timing is supported by a highly precise 1/100-second stopwatch capable of measuring elapsed times, split intervals, and 1st-2nd place finishes up to 999 hours, 59 minutes, and 59.99 seconds. It also features a 24-hour countdown timer adjustable in 1-second increments, 5 independent daily alarms (with 1 snooze alarm), an hourly time signal, switchable 12/24-hour time formats, and a full auto-calendar pre-programmed to the year 2099.
The case is engineered with commanding, oversized proportions, measuring an official 48.8mm in case width (diameter), a lug-to-lug length of 51.9mm, a heavy-duty profile thickness of 16.9mm, and a total weight of 99.0 grams. Dial protection is provided by a heavy-duty, scratch-resistant flat mineral crystal glass recessed safely below the protective lip of the stainless steel bezel. Built for extreme outdoor and aquatic recreation, the solid case structure and stainless steel caseback secure a certified 20-bar (200 meters / 660 ft) water resistance rating, making it completely safe for swimming, snorkeling, surfing, and heavy water sports. The watch comes fitted with an integrated black resin strap featuring a unique uneven texture achieved through special hot-stamping techniques (fitting wrist circumferences from 145 to 215 mm), fastened with a sturdy stainless steel pin buckle.
