CASIO G-SHOCK FROGMAN 35TH ANNIVERSARY MAGMA OCEAN GWF-1035F-1JR MADE IN JAPAN JDM (Japanese Domestic Market)
These new 35th Anniversary MAGMA OCEAN models mark the 35 years since G-SHOCK first started on its mission of unmatched timekeeping toughness back in 1983.
The band surfaces, back cover, metal parts and face are accented with G-SHOCK red, along with brilliant red gold and yellow gold coloring to commemorate G-SHOCK’s 35th anniversary.
These models incorporate the basics of the early G-SHOCK of 35 years ago while at the same time adding new value with a theme based on the magma ocean that covered the Earth at its beginning.
Base models are the MTG-B1000 MT-G, which packs absolute toughness into a refined metal design, the GPR-B1000 RANGEMAN that was designed with survivalist toughness in mind, and the GWF-1000 FROGMAN diver’s watch.
2018 also marks the 25th anniversary of the FROGMAN model, which first appeared back in 1993. To mark the occasion this model sports the image of a diving frog in various locations. Some of these locations are not normally visible, so the wearer can even enjoy playing a game of “Where’s the diving frog?” for a long time to come.
Features that identify these models as special timepieces are back covers impressed with the 35th Anniversary logo, and distinctive packaging.
