Description
The Casio G-Shock GMW-B5000PS-1DR (cataloged within the elite G-Shock 40th Anniversary Recrystallized Collection / Full Metal 5000 Series, and recognized in India under model code G1393) is an authoritative, high-performance Japanese light-powered quartz full-metal luxury collector's timepiece. Released to commemorate the monumental 40th Anniversary of G-Shock (1983–2023), this limited-edition masterpiece showcases breakthrough metallurgical processing developed specifically for this milestone anniversary series. Built upon the iconic full-metal GMW-B5000 architecture—which faithfully preserves the legendary square silhouette of the very first 1983 G-Shock DW-5000C—the GMW-B5000PS-1DR transforms high-grade stainless steel into an industrial work of art through a multi-stage regimen of thermal recrystallization, deep-layer carbon hardening, and a protective Titanium Carbide (TiC) surface coating. Across international horological circles, high-end collector forums, and G-Shock communities, it has earned defining community nicknames—the "Recrystallized Steel", "Deep-Hardened TiC", "Anniversary Square", "G1393 Silver", "Crystalline Steel Square", or "Recrystallized 40th Silver"—for its shimmering crystalline metal texture, matte gunmetal silver finish, DLC-coated screw-lock caseback, Tough Solar power engine, Multi Band 6 atomic timekeeping, and Bluetooth Smartphone Link connectivity. It unites a fine-resin-buffered solid stainless steel case measuring 43.2mm in width (49.3mm lug-to-lug) with a high-contrast digital display, mineral crystal glass, an in-house Japanese multi-motor caliber, and an integrated solid stainless steel multi-link bracelet. Weighing a solid 167.0 grams, it is meticulously calibrated for elite watch collectors, horological connoisseurs, and discerning executives seeking the pinnacle of luxury sports metallurgy.
The defining visual centerpiece of this GMW-B5000PS-1DR reference is its proprietary Multi-Stage Recrystallized and TiC-Coated Exterior. Every exterior stainless steel component—including the bezel, case body, push-buttons, and solid bracelet links—undergoes thermal recrystallization treatment to create a distinct, glittering crystalline grain pattern across the metal surface, ensuring that no two watches share the exact same visual texture. Following recrystallization, the steel components are subjected to a deep-layer carbon hardening process and finished with an advanced TiC (Titanium Carbide) coating, imparting a sophisticated gunmetal-silver luster that offers exceptional scratch and abrasion resistance. Adding unique commemorative detailing, a subtle star is laser-engraved onto the lower-left Mode button, while the phrase "SINCE 1983" is inscribed directly onto the dial face. The dial preserves the classic DW-5000C brick-pattern perimeter graphic, framed by high-contrast technical typography surrounding a high-visibility digital LCD screen. When the high-brightness white LED backlight (Super Illuminator) is engaged, it illuminates the display with crisp clarity. Turning the watch over reveals a heavy-duty solid stainless steel screw-lock caseback finished in a stealthy Diamond-Like Carbon (DLC) coating, deeply engraved with official G-Shock 40th Anniversary artwork designed by Eric Haze.
Beneath its artistic exterior, the watch is driven by Casio’s in-house Module 3459 Japanese Tough Solar digital quartz engine. Powered by Casio's proprietary Tough Solar light-harvesting technology, solar cells embedded around the display's perimeter convert natural sunlight and ambient indoor illumination into electrical energy stored in a secondary rechargeable battery, eliminating periodic battery replacements. On a full charge, the caliber provides approximately 10 months of autonomous operation under normal daily use without light exposure, and up to 22 months in Power Saving Mode when stored in total darkness. Absolute timekeeping precision is maintained through a dual-synchronization system: Multi Band 6 Atomic Radio Reception, which automatically calibrates with atomic time signals up to six times daily from transmitters in Japan, North America, the UK, Germany, and China; and Bluetooth Mobile Link via the CASIO WATCHES smartphone app, which performs automatic time correction four times daily, manages approximately 300 world time cities, provides a Time & Place log, and offers a Phone Finder feature. Operating independently without atomic or mobile signals, the module maintains a precision accuracy tolerance of ±15 seconds per month.
The watch features Casio’s legendary Full Metal Shock-Resistant Structure. To protect the electronic movement inside an all-steel housing, a shock-absorbing damping buffer made of high-durability fine resin is sandwiched between the solid stainless steel bezel and the inner core. The case measures an official 43.2mm in case width (diameter), a compact 49.3mm lug-to-lug length, a profile thickness of 13.0mm, and a total weight of 167.0 grams. Dial protection is provided by a heavy-duty, scratch-resistant flat mineral crystal glass recessed safely below the raised protective lip of the recrystallized bezel.
Built for heavy-duty active performance, the timepiece features a solid stainless steel screw-lock caseback treated with high-durability DLC coating, ensuring a certified 20-bar (200 meters / 660 ft) water resistance rating, making it completely qualified for swimming, marine recreation, and extreme outdoor environments. The comprehensive digital feature suite includes World Time across 39 time zones (39 cities + UTC), a 1/100-second precision stopwatch (measuring up to 24 hours with elapsed and split modes), a 24-hour countdown timer adjustable in 1-second increments, 5 daily alarms (with 1 snooze alarm), an hourly time signal, a full auto-calendar pre-programmed to the year 2099, customizable date/month display formats, and day-of-the-week readouts in six languages. The watch is completed on an integrated solid stainless steel multi-link bracelet featuring matching recrystallized TiC-coated steel and a one-touch 3-fold deployment clasp.
