Watch News: May 2026 — G-Shock Goes Magma, Seiko Adds a Compass, and the CasiCoke Is Here
The CasiCoke Has Arrived: G-Shock GA-2100CC-3A
The collaboration everyone saw coming is finally here. Casio and Coca-Cola have teamed up to celebrate the soft drink giant's 140th anniversary with a limited-edition CasiOak — the GA-2100CC-3A, already being called the 'CasiCoke' online.
Built on the beloved octagonal GA-2100 platform (the same base as our current Watch of the Week, the Orient Kamasu's spiritual G-Shock cousin), the GA-2100CC-3A features a translucent red resin case and band inspired by Coca-Cola's iconic red, with subtle Coke branding on the dial and a special commemorative packaging. The watch retains all the standard CasiOak specs: Carbon Core Guard structure, 200M water resistance, analog-digital display, and shock resistance.
Price: Approximately $160–$175 USD when it hits US shelves in May 2026. The Japanese release was priced at 27,500 yen and sold via online lottery — demand is high.
Our Take: The CasiOak is already one of the best-value watches on the market at $99–$110 for the standard black. At $160–$175 for the Coke edition, you're paying a ~$65 premium for the collab. If you're a Coca-Cola collector or just love the red aesthetic, it's worth it. If you want the best bang for your buck, the standard GA-2100-1A1 is still the smarter buy. Either way, this is a watch that will hold its value — limited collabs like this tend to appreciate.
Lava Meets Legend: G-Shock Mudmaster GWG-B1000MG-1A9
For those who want something more serious, Casio also dropped a limited-edition Mudmaster that looks like it was forged in a volcano. The GWG-B1000MG-1A9 features magma-inspired orange hands and markers, gold-toned ion-plated stainless steel accents, and a black resin band mix-molded with lighter shades to resemble geological strata.
This is not a budget watch — it's priced at 143,000 yen in Japan (approximately £800 in the UK) — but it represents the pinnacle of what G-Shock engineering can do. The GWG-B1000MG-1A9 is Japan-made and packs sapphire glass, Tough Solar, Multi-Band 6 atomic timekeeping, Bluetooth, and the Triple Sensor (altimeter-barometer, compass, thermometer).
Our Take: The Mudmaster is the watch we covered in our most-watched YouTube video (34K views and counting). This magma edition is a collector's piece. If you've been eyeing a Master of G watch and have the budget, this limited run won't last long. For most of us, the standard GWG-B1000-1A at around $400 delivers the same core technology at a fraction of the price.
A New Direction for G-LIDE: The GBX-H5600 Series
Casio also unveiled the all-new G-LIDE GBX-H5600 series this month — a completely fresh take on the G-LIDE surf/water sports line. The GBX-H5600 builds on the classic DW-5600 square case silhouette (the same DNA as the original 1983 G-Shock) but adds a new high-brightness display, moon data, tide graphs, and Bluetooth connectivity.
The GBX-H5600 is aimed squarely at surfers, paddlers, and water sports enthusiasts who want tide and moon data without sacrificing the G-Shock's legendary toughness. It's a direct evolution of the G-LIDE line that has been popular with the surf community for years.
Price: Not yet confirmed for US pricing, but expect it in the $150–$200 range based on comparable G-LIDE models.
Our Take: If you're a water sports person who wants a purpose-built tool watch, the GBX-H5600 is worth watching closely. The DW-5600 form factor is one of the most wearable G-Shock shapes — slim, lightweight, and iconic.

Seiko Gives the 5 Sports a Compass: HDB006, HDB007, HDB008, HDB009
Seiko has been quietly building one of the most comprehensive affordable watch lineups in the industry, and May 2026 adds another chapter: four new Seiko 5 Sports Field models with a compass bezel.
The HDB006 through HDB009 are all technically identical but come in two distinct personalities. The HDB006 (black dial) and HDB007 (white dial) come on steel bracelets with a brushed steel bezel. The HDB008 (green dial, black bezel) and HDB009 (brown dial, brown bezel) come on nylon-leather straps with a hard-coated bezel for an adventure-ready look.
All four share the same specs: 41mm stainless steel case, 13.2mm thickness, 100M water resistance, bidirectional compass bezel, and Seiko's proven Calibre 4R36 automatic movement with 41 hours of power reserve. Crucially, Seiko has added LumiBrite to the Arabic numerals — something the previous 5 Sports Field watches were missing.
Price: EUR 390 on strap (HDB008/HDB009) and EUR 410 on bracelet (HDB006/HDB007). Available worldwide in June 2026.
Our Take: This is exactly the kind of release we love covering. Seiko is taking a proven, affordable platform and making it genuinely better — adding the compass bezel that field watch fans have been asking for, upgrading the lume, and keeping the price under EUR 420. The HDB008 in green with the black bezel is the standout for us: it looks like a mini Alpinist at a fraction of the price. We'll be watching pre-order availability closely.
Timex Revives a Classic: The 1976 Lexington Under $200
Not every great watch story in May 2026 involves G-Shock. Timex has quietly dropped what may be the best dress watch under $200 right now: the 1976 Lexington.
Named after the year it was originally designed, the Lexington is a clean, slim dress watch with a sunray-brushed dial, applied indices, and a leather strap. It's the kind of watch you can wear to a job interview or a wedding without anyone questioning your taste — and at under $200, it's a remarkable value in the dress watch category where Swiss brands typically start at $500.
Our Take: Timex doesn't get enough credit for their dress watch lineup. The Marlin has been a cult favourite for years, and the Lexington looks like it could join that conversation. If you've been looking for an affordable dress watch to complement your G-Shock collection, this is worth a serious look.
What We're Watching: The Audemars Piguet Collab Under $500
In genuinely surprising news, Audemars Piguet — maker of the Royal Oak that inspired the CasiOak nickname — has announced a collaboration with an affordable watch brand that could result in pieces under $500. Details are still emerging as of publication, but this is the kind of trickle-down luxury story that the watch world lives for.
We'll cover this in full once more details are confirmed. For now, it's worth noting that the lines between luxury and affordable watchmaking continue to blur in fascinating ways — and that's great news for value-focused collectors like us.
The Bottom Line
May 2026 is a strong month for anyone who believes you don't need to spend thousands to wear something great on your wrist. The CasiCoke is a fun limited edition, the Mudmaster MG is a collector's dream, the new G-LIDE opens up the DW-5600 platform to water sports, the Seiko 5 Sports Field compass models are a genuine upgrade to an already excellent lineup, and Timex is quietly making some of the best dress watches under $200.
We'll be updating this roundup as US pricing and availability are confirmed for the Seiko HDB series and the new G-LIDE. In the meantime, check out our Watch Advisor to find the right watch for your budget and lifestyle — or browse our Best Watches Under $200 guide for our current top picks.
