Casio G-Shock GWF-A1000 Watches

Introducing the first analog models for the FROGMAN Series of MASTER OF G ISO 200 m diver-level water resistant watches.
Maintaining the asymmetrical face design that has been the iconic look of this series since its start in 1993, these new models show Home Time, Dual Time, tide information, and dive time measurement in analog format. Large, luminescent hour and minute hands improve readability, and the face is designed to provide intuitive indication of measurement information.


Enjoy Japanese approaches to Tough and Functional Watches!

Analog Watch Display. A first for the FROGMAN: an analog display. The over-sized dimensional index and hour and minute hands offer improved readability. Three dual-coil motors enable the hour, minute and world time hands to move rapidly so the wearer can switch modes with no delay.

ISO 200-Meter Diving Water Resistance. The monocoque case integrates the case with its back cover. Carbon fiber reinforced resin is used for the case material, offering high strength and low absorbency.

Fluoroelastomer Band. The fluoroelastomer material provides an excellent fit on the wrist with its soft feel, not to mention exceptional resistance to staining and hydrolysis.

Diving Mode. 1. The hour and minute hands can be brought together as one at the start of a dive to indicate the diving time.
2. After resurfacing will display the surface interval using both hands. The second hand moves forward or in reverse to indicate the status of dive time and surface interval measurements.

Tide Mode. The inset dial at the 3 o’clock position displays tide data for a specified location and date. The inset dial at the 8 o’clock position shows the current local time. The app comes pre-set with some of the world’s major dive spots. Tide points can be set with ease.

Sapphire Crystal with Non-Reflective Coating + Super Illuminator
(High-Brightness LED Light) Sapphire crystal with a non-reflective coating offers high visibility and scratch-resistance. The Super Illuminator function lights up the watch face with high-intensity light, to ensure readability in the dark.

Bluetooth® + Radio-controlled, solar-powered timekeeping. Time correction is conducted by either Bluetooth® communications or standard time radio wave (Multi Band 6), depending on the circumstances. Reception of the most recent time zone and Daylight Saving Time information assures that the correct time is displayed at all times.

Sapphire crystal with non-reflective coating. To ensure high readability, non-reflective coating is applied on the scratch-resistant sapphire crystal.

In addition to great designs, these new models also incorporate advances in material, structure, and function. The monocoque structure of this model incorporates the case and back cover into a single unit. The carbon fiber-reinforced resin has a low water absorption coefficient and resists hydrolysis, which results in a higher level of water resistance and greater strength. This, along with the monocoque case, enables ISO 200 m diver-level water resistance.
The external structure that capitalizes on the high strength and lightweight characteristics of the material improves toughness and reduces weight by 22 grams compared with previous GWF-D1000 Series models.
