Casio G-Shock FROGMAN Radio-Controlled Solar Diver’s Watch GWF-1000-1JF Men’s Black [Official Japanese Product]

Product Introduction

The Master of G series, designed for use in harsh environments, now features the newly released FROGMAN, a solar-powered radio-controlled watch with exceptional water resistance.

Thanks to a newly developed receiving antenna and metal case, this watch is ISO 200m diving-proof while receiving time-calibration radio waves from six stations worldwide. It also features 10 log data memories, a high-speed tide graph, and high-precision moon data. The stopwatch, which is frequently used during diving, has enlarged buttons for underwater operation. The fully automatic EL backlight illuminates the LCD screen vividly, even while diving, simply by tilting your wrist. The protective cover, band, and bezel that cover the back of the case are secured with screws from the side for improved shock resistance, and the band has been designed without unnecessary protrusions for a comfortable fit. This watch is packed with practical features, making it a genuine diver’s watch suitable for use in oceans around the world.
Attention to detail and texture exudes a bold, rugged design. The front screws on the top of the bezel are made of machined stainless steel, while the edges of the circular dial display are made of machined high-brightness aluminum. The screw-back metal case is DLC-treated and has a mirror finish. Equipped with the latest technology, this practical and high-quality new FROGMAN from the Master of G series can withstand the rigors of use at sea. Features include:

Brand introduction

G-SHOCK established a new concept of toughness in watches. It all began with the passionate belief of its developers in creating a watch that would not break even if dropped, a seemingly foolhardy challenge that overturned conventional wisdom at the time. After more than 200 prototypes and roughly two years of work, the shock-resistant structure was finally completed. This was the birth of the technology that forms the core of toughness. Since then, G-SHOCK has continued to evolve endlessly, pursuing even greater toughness in every aspect: structure, materials, and functionality.
