G-Shock G-7700-1DR

These G-SHOCK models are designed and engineered for the rugged, 1/1000-second world of motor sports. Motor sports functions include a 1/1000-second stopwatch, stopwatch with auto-start function, lap memories, and much more. Oversized buttons allow easier operation. The 48-city World Time Mode includes cities where the world?s biggest motor sports events are held and simultaneous access to the current times in three different time zone. A three-line display and peripheral graphic area creates the image of a high-tech meter panel, while a metal bezel add a hard, mechanical accent. LEDs flash from red to green in coordination with auto start timer operation, just like the lights at the start of a motorcycle.
Mechanical design
The functional face design with its three-column digital display and graphic display on the LCD periphery projects a racing gauge image. This combines with the rigid-textured metal bezel to form a mechanical face with a distinctive motorsport perspective.
1/1000-second stopwatch
A newly developed module has been adopted to support a high-precision 1/1000-second stopwatch function. Other useful functions for viewing motorsport and other events include an auto start function, total elapsed time/lap time display switch and lap time memory. The auto start function conducts a 5, 4, 3, 2, 1 countdown before the stopwatch engages.
World Time
The highly practical World Time feature displays the times in three different cities simultaneously. It?s preset for 48 cities worldwide, with a focus on countries where major motor races are held. And, of course, summer time setting is selectable as well.
LED indicator
The built-in LED glows from red to green in conjunction with the stopwatch?s auto start function as well as in the timer mode.
