The metal G-Shock that completed the design
The original Casio G-Shock DW-5000C was launched in April 1983: a square resin-cased shock-resistant digital watch designed by Kikuo Ibe to survive a 10-meter drop. For 35 years G-Shock made variants of this Square, but always in resin. In April 2018, for the 35th anniversary, Casio released the GMW-B5000 with the Module 5611: the same case dimensions and the same digital aesthetics as the 1983 DW-5000C, but built entirely in stainless steel (case + bracelet) for the first time.
Why this watch is on every collector's shortlist
The GMW-B5000 has unusual breadth of appeal:
- Heritage: it is the original 1983 design in metal, the watch the original DW-5000C "always wanted to be"
- Build: full stainless steel construction (resin only on the inner case for shock absorption)
- Tech: atomic-clock radio sync (6 stations worldwide, including JJY Japan, WWVB USA, MSF UK, DCF77 Europe, BPC China, and a sixth Chinese signal), Bluetooth smartphone time-set, Tough Solar charging
- Wearability: 43.2 × 49.3 × 13 mm, 167 g, fits typical wrists
- Price: USD 550 retail (gold-PVD versions higher)
The combination of heritage design, modern tech, and reasonable price made the GMW-B5000 the most-desired G-Shock since the original Square.
Variants
The Module 5611 powers a growing GMW-B5000 family:
- GMW-B5000D-1: standard silver/grey on steel bracelet (the iconic "metal Square")
- GMW-B5000GD-9: yellow gold-IP coated steel ("gold Square")
- GMW-B5000GD-1: black-IP "stealth" finish
- GMW-B5000PB-6: rainbow titanium-PVD
- GMW-B5000TR-9: titanium with 18k yellow-gold IP highlights (limited)
- GMW-B5000-1JF: Japan-domestic variant
Plus various collaboration LE editions (Eric Haze, Ennoy, Tiffany, etc.) released regularly.
Module philosophy: digital reliability
The Module 5611 is a digital quartz, not analogue. The Tough Solar system charges from any light source through the dial; full charge gives 26 months of reserve in complete darkness. The atomic-clock radio sync ensures the watch never drifts more than a few seconds; if radio sync is unavailable, smartphone Bluetooth sync (via the G-Shock Connected app) provides a backup. World time covers 39 cities + UTC; alarms, stopwatch (1/100 second resolution), countdown timer, and full-auto calendar through 2099 round out the functions. Service: Casio recommends battery cell replacement every 7-10 years (the lithium-ion cell ages even with solar charging).
Where it sits in horology and culture
The GMW-B5000 occupies an unusual position. To traditional watch collectors, a $550 quartz Casio sits outside the conversation. To the broader watch world, it is now one of the most-recognised non-Swiss watches of the 2020s: worn by Kanye West, Jonathan Anderson, James Stacey, and many high-profile watch enthusiasts as a counterpoint to mechanical pieces. Casio's argument with the GMW-B5000 is that watch design and watch tradition are not the exclusive domain of mechanical Swiss watches; the 1983 DW-5000C is now itself a 40+ year heritage object, and the metal version is its definitive form.
