The Sunstone Adventurer's Watch is made of stainless steel and features mineral colors that ancient sailors used to wear on their voyages. Forging, ion plating and masking techniques have been used to create the unique look of its bezel. Its digital dial features the words 'SINCE 1983' to remind users of the brand's long history, while the 40th anniversary logo designed by Eric Haze is engraved on the case back. Finally, the Casio watch strap is made of black resin and has a unique texture thanks to hot stamping and Garal color molding techniques.
