CASIO

1. CASIO CLASSIC (AQ-240E Series)

The AQ-240E carries on the simple, square-faced silhouette of the AQ-230 but wraps it in a softly rounded case, giving the design a rounder, more polished feel while keeping its vintage character. The dial gets a sunburst finish that shifts in appearance with the light, and a slim digital display at 6 o’clock balances legibility with the model’s classic analog look. Under the hood is CASIO’s Module 5154, which adds dual time display, a 1/100-second stopwatch with a 60-minute timer, a daily alarm and hourly chime, a fully automatic calendar, and 12/24-hour switching, with roughly 3 years of battery life. This month’s two new colorways — a glossy black and a deep navy — are both set in a silver resin case on a stainless steel band, aiming for a cool, versatile look that works from business to casual wear.

G-SHOCK

2. MASTER OF G – FROGMAN

Master of G is G-SHOCK’s toughest sub-line, split into dedicated “Sea,” “Land,” and “Sky/Mountain” tool watches. FROGMAN is the Sea specialist — a purpose-built diver’s G-SHOCK with a depth gauge, water temperature sensor, and dive log, worn by professional and recreational divers alike.

GWF-D1000BC-1JF is the first new FROGMAN colorway since 2019, finished in a stealthy all-black case with tan accents and a DLC-coated bezel. It keeps the model’s core dive toolkit — ISO 200m water resistance, an 80m-range depth gauge, a water thermometer, and an underwater-compensated digital compass — and switches to a new composite metal-and-resin band with a two-stage extension so it can be worn over a wetsuit. It’s powered by Tough Solar charging with Multiband 6 radio time correction, and is fitted with a sapphire crystal.

3. MASTER OF G – MUDMASTER

MUDMASTER is Master of G’s Land specialist, built for dusty, muddy, and debris-heavy environments and trusted by rangers and rescue crews for its dust- and mud-resistant construction. Its Carbon Core Guard case blends a high-strength carbon-fiber-reinforced resin shell with precision-forged metal parts for extra durability.

GWG-B1000-1A3JF carries the flagship GWG-B1000’s full toolkit — a Triple Sensor for compass, barometer/altimeter, and thermometer readings, double LED lighting, and a sapphire crystal — in an olive-and-tan colorway. It runs on Tough Solar charging with Multiband 6 radio time correction and is rated to 20 bar (200m) water resistance.
