These new 35th Anniversary GLACIER GOLD models mark the 35 years since G-SHOCK first started on its mission of unmatched timekeeping toughness back in 1983.The bezels, cases, and bands of these watches are made of clear semi-transparent material in designs embodying motifs that combine the harsh conditions you might expect to encounter on a freezing glacier with the image of G-SHOCK toughness that is able to stand up to such conditions. The clear semi-transparent style was first used back is 1996 for the G-SHOCK Dolphin & Whale models, and the global popularity of this design makes it an important turning point in G-SHOCK history.
