GWFA1000APF1A | G-SHOCK MASTER OF G - SEA Transparent color | CASIO

The FROGMAN 30th anniversary model


My GShock

Dive into the celebration of the 30th anniversary of the G-SHOCK Master of G FROGMAN family of full-fledged diver’s watches with ISO-standard 200-meter water resistance. The first-ever FROGMAN made quite a splash when it launched back in 1993. The second limited edition to commemorate the 30th FROGMAN anniversary in 2023 takes the GWFA1000 to a whole new level, with a special design inspired by the poison dart frog. The multicolor carbon bezel evokes the mysterious hues of this rare species of colorful frog living in the South American Amazon. Cut from a base material of colorful carbon and glass fibers laminated in random patterns, no two bezels are exactly alike, reflecting the rarity of this frog species. The combination of strikingly colorful bezel and translucent urethane reproduces the look and feel of the water-loving poison dart frog. The band is printed with polarized ink to evoke the speckled pattern of a frog — a touch repeated on the case back with the iconic frog character reimagined as a poison dart frog.

Multicolor carbon bezel evokes
colorful poison dart frog

Vivid black, orange, and blue interwoven in organic patterns evoke the beautiful colors of the poison dart frog.* The bezel is cut out from a base material of laminated carbon and glass fibers. No two are exactly alike, reflecting the rarity of this frog species. The multicolor design is highlighted by the use of similar colors on the dial and clear resin for bezel components.

*The poison dart frog takes its name from the fact that indigenous people of the Amazon applied the frog’s venom to their hunting arrows. These frogs are known for their beautiful colors and colorful patterns, called warning coloration and meant to keep enemies away.
*Exact bezel patterns will vary from watch to watch due to details of the manufacturing process.

Polarized fluorine band

The band is coated with a polarized spray to create the look of the poison dart frog. The polarized paint changes colors depending on the light and angle from which it is viewed. Made from fluoroelastomer, the band is highly stain resistant and able to withstand exposure to humidity.

ISO 200-meter water resistance in a Carbon Core Guard structure (carbon monocoque case)

The monocoque case integrates the case with its back cover. Six screws securely fasten the metal ring that is press-fit to the glass, and the button shafts are equipped with triple-gasket fittings. These and other features keep the watch air-tight to achieve ISO 200-meter diving water resistance. Low-absorbent carbon fiber-reinforced resin is used as the case material for a watch that is both strong enough to withstand hard use and lightweight enough to be worn comfortably for long periods of time.
