This is the DW-5000C-1A, which was born in 1983. It's the origin of G-SHOCK, leaving a strong impression. The design intentionally emphasizes volume to highlight its toughness, evoking the image of a tire. The specifications at the time included shock resistance and 20-bar water resistance. It was quite advanced, with a stopwatch, timer, time alarm, 12/24-hour display switching, auto calendar, and more. The entire watch is covered in urethane, and the module, which is the heart of the watch, uses a hollow structure that supports it with rubber packing, allowing it to float within the case. You can use it with confidence in tough environments. It's a wristwatch that has been supported by unwavering popularity throughout the ages. I purchased this watch for several hundred thousand yen at a G-SHOCK consignment store in Osaka during the peak of G-SHOCK popularity about 30 years ago, and I have kept it in amateur storage without ever using it. I am a G-SHOCK fan, but not a maniac, so I will explain what I know. The bezel was purchased at a ○○ auction a few years ago because it had deteriorated. The belt has miraculously never been replaced. I believe it is the original belt. Please check the photos. In the second image, there are some areas where the white outline of the watch is peeling, but it has been in that condition since I bought it. The images are everything. The box is also valuable, but there is some staining on the side. I think it is in a relatively clean condition for something from over 30 years ago. Please understand that it is an old item before purchasing. No claims and no returns, please. #G-SHOCK
