(The Gear Loop) - Can you believe that Casio G-Shock is turning 40 next year? We can’t either, but the brand is busy celebrating this long, illustrious and shock-proof career with an array of striking new watches.

The first to be released are the succinctly-named MTG-B3000FR-1AER and GWG-2040FR-1AER, two Flare Red anniversary models that feature laminated bezels made with phosphorescent materials. These eye-catching bezels evoke "solar flares, the massive eruptions of intense energy from the sun’s surface".

To achieve that eye-popping colour, Casio used a newly-developed technique that laminates carbon and coloured glass fibre sheets together. Phosphorescent particles mixed into the glass fibre layers catch the light and even subtly glow in the dark, making it look bright and dazzling during the day, while a throbbing green-ish glow can be seen when the sun drops.

For the GWG-2040FR-1AER (or Mudmaster), phosphorescent particles are also mixed into the forged carbon of the lugs that connect the case to the band.

According to Casio, no two watches from this series look the same, as the high grade forged carbon found in the casings features 500,000 intertwined fibres per square inch, all of which can be slightly different.

The MTG-B3000FR-1AER, which is hand-assembled in Yamagata Japan will retail at £1,300 when it is officially launched on the 27th of October this year, while the GWG-2040FR-1AER Mudmaster will cost £950. This solar-powered model features a compass, altimeter, barometer and thermometer for serious outdoor chops.
