What are the Casio May 2026 releases?
The May 2026 release cycle is built on three main pillars. First, we’ve got high-profile pop-culture collaborations. The partnership with Star Wars and Coca-Cola has produced some of the most collectible G-SHOCK models in recent memory. These aren’t just color swaps; they feature custom engravings, specialized materials like bio-based resins, and unique display stands that appeal to both watch enthusiasts and franchise collectors.
Second, Casio is aggressively expanding the health and fitness capabilities of its professional lines. The new G-LIDE series now includes optical heart rate monitors and blood oxygen measurement, bringing it closer to a full-fledged smartwatch while maintaining the legendary “Triple 10” toughness.
Finally, the CASIO Classic and “Collection” lines continue to revive retro silhouettes with modern finishes. These models provide incredible value, offering iconic designs with updated steel bracelets and sunray dials that punch well above their price point.
Selection criteria for this list
Curating the best New Casio Men’s Watches May 2026 requires looking beyond just the aesthetic. We evaluated dozens of new arrivals based on four key factors:
- Innovation: We prioritized models that introduce new technology to their respective lines, such as the first heart rate monitor in a square G-LIDE.
- Collectibility: Limited edition collaborations that are likely to hold or increase in value are high on our list.
- Build quality: We focused on “Domestic Genuine Product” (JDM) models, which often feature superior finishing and authentic Japanese craftsmanship.
- Value for money: Whether it’s a $20 retro classic or a $2,000 Oceanus, each watch must justify its price through features and durability.

Top 7 new Casio men’s watches for May 2026
1. G-SHOCK x Star Wars GM2100-1A “The Mandalorian”
This is the big one for collectors. The G-SHOCK x Star Wars GM2100-1A is the first official collaboration with the Star Wars universe, timed for the upcoming “The Mandalorian and Grogu” movie. It uses the fan-favorite octagonal metal-covered bezel, but with a twist. The silver stainless steel has been forged and finished with a rugged, industrial texture designed to look like Beskar armor.
The details are everywhere. From the character-specific engraving on the case back to the “Bounty Hunter ID Card” that transforms into a 3D magnetic watch stand, this is a premium package. It’s not just a toy, either. With 200m water resistance and the Carbon Core Guard structure, it’s built to survive a trip to the Outer Rim or your daily commute.
- Pros: Unique Beskar-inspired metal finish, highly collectible limited packaging, and includes a magnetic display stand.
- Cons: The resin strap might feel less premium than a full metal bracelet.
| Feature | Specification |
|---|---|
| Case Size | 49.3 x 44.4 x 11.8 mm |
| Battery Life | Approx. 3 years |
| Weight | 72g |
2. G-SHOCK Coca-Cola Edition GA-2100CC-3A
To celebrate 140 years of the world’s most famous beverage, G-SHOCK released this GA-2100CC-3A. The colorway is the standout feature here, with a translucent green bezel and band that perfectly captures the look of a classic Coca-Cola glass bottle.
The design team went deep on the details. The date indicator hand at the 9 o’clock position and the band loop both feature the fluted bottle motif. Even the case back is engraved with a bottle cap design. It uses bio-based resin, showing our commitment to more sustainable materials in the watch industry. It’s a fun, lightweight (51g) piece that brings a bit of pop-art to your wrist.
- Pros: Iconic bottle-green aesthetic, sustainable bio-based materials, and unique vending machine-style packaging.
- Cons: It carries a price premium over the standard non-collaboration GA-2100.
| Feature | Specification |
|---|---|
| Case Size | 48.5 x 45.4 x 11.8 mm |
| Price | $200.00 |
| Special Feature | Coca-Cola 140th Anniversary Collab |
3. G-SHOCK G-LIDE GBX-H5600-1JR
The GBX-H5600-1JR represents a major tech leap for the surfing-focused G-LIDE series. For the first time, Casio has integrated an optical heart rate monitor and blood oxygen (SpO2) measurement into this line. It uses the Polar™ library to provide detailed workout analysis, cardio load status, and sleep recovery tracking.
Despite the addition of these sensors, it maintains the classic square shape fans love. The high-definition MIP LCD ensures you can see your tide graphs and heart rate data clearly even in bright sunlight. It also features solar-assisted charging, so you won’t be tethered to a USB cable for basic timekeeping. We find this to be the perfect middle ground for someone who wants the durability of a G-Shock with the health insights of a modern fitness tracker.
- Pros: Advanced health sensors in a classic square case, solar-assisted charging, and high-definition MIP display.
- Cons: Using the heart rate monitor and Bluetooth continuously will significantly reduce the time between USB charges.
| Feature | Specification |
|---|---|
| Sensors | Heart Rate, SpO2, Accelerometer |
| Price (JDM) | 44,000 YEN |
| Special Feature | Polar™ Workout Analysis |
4. Oceanus Manta OCW-S7000AP-1AJF
If you’re looking for the pinnacle of Japanese watchmaking, the Oceanus Manta OCW-S7000AP-1AJF is it. This model is limited to only 1,300 pieces worldwide and features “Awa Indigo,” a natural dye from Tokushima Prefecture. The in-dials are colored with pigments derived from this traditional indigo, creating a deep, shifting “Japan Blue” that changes depending on the light.
The construction is pure luxury. It features a full titanium case and band with a specialized TIC coating for scratch resistance. The bezel is finished with Zaratsu polishing, creating a distortion-free mirror finish. At just 9.5mm thick, it’s incredibly slim for a watch that includes Bluetooth and Tough Solar technology. It’s a “Made in Japan” masterpiece that represents the very best of what we offer.
- Pros: World-class Zaratsu finishing, rare Awa Indigo traditional dyeing, and an incredibly lightweight titanium build.
- Cons: Premium price point over 260,000 YEN makes it an investment piece.

5. Casio Classic A140WEG-9AJF
Not every great release needs to cost thousands of dollars. The Casio Classic A140WEG-9AJF is part of a new retro-digital series that has taken the enthusiast community by storm. This specific model features a gold-tone finish with a beautiful sunray dial that adds a layer of sophistication to the vintage silhouette.
The standout feature here is the herringbone-patterned steel bracelet. It feels much more elegant than the standard digital straps and helps the watch transition from casual wear to more formal settings. With a 7-year battery life and a price in the $70 range, it’s an easy “impulse buy” that you’ll find yourself wearing more often than you expect. It proves that Casio still knows how to do budget-friendly style better than anyone else.
- Pros: Elegant sunray dial and unique herringbone bracelet, 7-year battery life, and excellent value for money.

| Series | Casio Classic |
6. PRO TREK Climber Line PRW-61D-2JF
For the outdoor adventurers, the PRO TREK PRW-61D-2JF is this month’s top pick. This “Climber Line” model features the famous Triple Sensor technology, giving you access to an altimeter, barometer, and digital compass right on your wrist.
What makes this model special is the focus on sustainability. The case and strap are made from biomass-based plastics, reducing the environmental footprint of your gear. It also includes Tough Solar power and Multi-Band 6 atomic timekeeping, ensuring you always have the correct time, no matter how deep into the wilderness you go. The blue colorway is a JDM exclusive that looks fantastic in person.
- Pros: Full suite of outdoor sensors, eco-friendly biomass construction, and atomic timekeeping for perfect accuracy.

7. G-SHOCK Mudmaster GWG-B1000MG-1A9JR
If the Mandalorian watch is for the outer rim, the Mudmaster GWG-B1000MG-1A9JR is for the harshest environments on Earth. This new Black X Gold edition brings a luxury touch to a watch that’s practically indestructible. The mud-resistant structure uses multiple gaskets to prevent sand and debris from entering the case.
It’s packed with tech, including a Triple Sensor and Bluetooth connectivity for location logging via the app. The Carbon Core Guard structure keeps it relatively light for its size, but make no mistake, this is a “beast” of a watch. It’s built for those who need a tool that can take a beating and still look premium on the wrist.
- Pros: Ultimate mud and shock resistance, striking Black X Gold colorway, and full Bluetooth/Sensor suite.
- Cons: It’s a very large and bulky watch that won’t fit under most shirt sleeves.

| Key Sensors | Triple Sensor (ABC) |
| Price (JDM) | 180,180 YEN |
Tips for choosing your next Casio watch
With so many New arrivals every month, it can be hard to decide which one’s right for you. The first step is to identify your primary use case.
