A model equipped with a high-brightness LED backlight from G-SHOCK, which continues to evolve in the pursuit of toughness. Use of a high-brightness LED system and a light guide plate makes the watch easy to read even in the dark. It also has practical functions such as world time, an alarm, and a stopwatch. The color is classic G-SHOCK black, and the brand-color red is used as an accent throughout. .cc-gd100{ --ink:#16181C; --panel:#1A1D22; --paper:#FFFFFF; --soft:#F4F5F6; --line:#E4E6E9; --muted:#6B7178; --accent:#FF5A1F; --mono:ui-monospace,"SFMono-Regular",Menlo,Consolas,"Liberation Mono",monospace; --sans:"Helvetica Neue",Arial,system-ui,-apple-system,Segoe UI,Roboto,sans-serif; color:var(--ink); font-family:var(--sans); line-height:1.5; max-width:1040px; margin:0 auto; -webkit-font-smoothing:antialiased; } .cc-gd100 *{box-sizing:border-box;} .cc-gd100 .cc-head{margin:0 0 22px;} .cc-gd100 .cc-model{ display:inline-block; font-family:var(--mono); font-size:12px; letter-spacing:.14em; text-transform:uppercase; color:var(--accent); border:1px solid var(--accent); border-radius:3px; padding:4px 9px; margin-bottom:12px; } .cc-gd100 h2{ font-size:26px; line-height:1.15; font-weight:800; letter-spacing:-.01em; margin:0; } .cc-gd100 .cc-sub{ color:var(--muted); font-size:15px; margin:8px 0 0; max-width:62ch; } /* Hero highlights */ .cc-gd100 .cc-hero{ display:grid; grid-template-columns:repeat(6,1fr); gap:10px; background:var(--panel); border-radius:12px; padding:18px; margin:0 0 28px; } .cc-gd100 .cc-hero .h{text-align:center;color:#fff;padding:6px 4px;} .cc-gd100 .cc-hero .h svg{width:30px;height:30px;stroke:var(--accent);margin-bottom:8px;} .cc-gd100 .cc-hero .h b{display:block;font-size:13px;font-weight:700;line-height:1.25;} .cc-gd100 .cc-hero .h span{display:block;font-size:11px;color:#9AA1A9;margin-top:2px;} /* Spec groups */ .cc-gd100 .cc-grid{display:grid;grid-template-columns:repeat(2,1fr);gap:18px;} .cc-gd100 .cc-card{ background:var(--paper); border:1px solid var(--line); border-radius:12px; padding:6px 18px 14px; } .cc-gd100 .cc-card.cc-wide{grid-column:1 / -1;} .cc-gd100 .cc-card h3{ display:flex; align-items:center; gap:8px; font-family:var(--mono); font-size:12px; letter-spacing:.12em; text-transform:uppercase; color:var(--ink); padding:14px 0 4px; margin:0; } .cc-gd100 .cc-card h3 .tab{width:18px;height:3px;border-radius:2px;background:var(--accent);} .cc-gd100 .cc-rows{display:grid;grid-template-columns:1fr;} .cc-gd100 .cc-card.cc-wide .cc-rows{grid-template-columns:repeat(2,1fr);column-gap:26px;} .cc-gd100 .cc-row{ display:flex; align-items:flex-start; gap:12px; padding:12px 0; border-top:1px solid var(--line); } .cc-gd100 .cc-row .ic{ flex:0 0 auto; width:34px;height:34px; display:flex;align-items:center;justify-content:center; background:var(--soft); border-radius:8px; margin-top:1px; } .cc-gd100 .cc-row .ic svg{width:18px;height:18px;stroke:var(--ink);} .cc-gd100 .cc-row .tx{flex:1 1 auto;min-width:0;} .cc-gd100 .cc-row .lbl{ font-size:12px; letter-spacing:.04em; text-transform:uppercase; color:var(--muted); margin:0 0 2px; } .cc-gd100 .cc-row .val{ font-family:var(--mono); font-size:14px; color:var(--ink); margin:0; word-wrap:break-word; } .cc-gd100 .cc-row .val .note{ display:block; font-family:var(--sans); font-size:12px; color:var(--muted); margin-top:3px; } .cc-gd100 .cc-foot{font-size:12px;color:var(--muted);margin:22px 0 0;} @media (max-width:760px){ .cc-gd100 .cc-hero{grid-template-columns:repeat(3,1fr);} .cc-gd100 .cc-grid{grid-template-columns:1fr;} .cc-gd100 .cc-card.cc-wide .cc-rows{grid-template-columns:1fr;} .cc-gd100 h2{font-size:22px;} } @media (max-width:420px){ .cc-gd100 .cc-hero{grid-template-columns:repeat(2,1fr);} } GD100-1B G-Shock GD100-1B A big, blacked-out digital build that runs for years.
