CASIO PROTREK PRG-40 ※ I am also selling a "Near-Mint Red PRG30." Please take a look if you're interested. 〇 Rare blue PRG40. This color is rarely seen. Many people may not even know this color variation exists. The actual color is darker than in photo ②, a cool color with a hint of navy. 〇 The main body, overall, has few shallow scratches and is very clean. There is no peeling of the paint on the letters. It doesn't feel like it's been used much. There is a scratch on the U-shaped part on the left side (photo ⑤). The crystal (glass surface) is clean. Please enlarge the photos to check. 〇 The bezel (the black frame indicating north, south, east, and west) also rotates smoothly. 〇 Works perfectly. Photos ⑫-⑮ compare it with the "White PRG40 (left)" and "Radio Solar PRW-1000 (right)" I own (the item for sale is in the center. The left and right watches are not included). Please use them as a reference. 　⑫ Basic screen. Day of the week, time, year, and date are displayed at once. 　⑬ Display screen of the direction immediately after correcting two points each. 　⑭ Atmospheric pressure and temperature display screen. 　⑮ Altitude display screen. 〇 The diameter of the crystal is about 32mm. A protective film of this size will fit. 〇 The letters are very easy to read. The PRG40 has a very clear contrast between the dial and the letters, so I find it very easy to read. I like it, so I also use the red and white PRG40s. 〇 It's also attractive that the basic screen displays "time and seconds (middle)", "day of the week (top)", and "year and date (bottom)" all at once. I don't think this is common even among other Pro Treks. 〇 Adjusting the time (setting the seconds) is really simple and easy. It can be done in the following 3 steps: 　➀ "Press and hold the upper left button" → "Seconds flash" 　② "Press the lower right button" →→ "Seconds reset to 0" 　③ "Press the upper left button" →→ "Flashing disappears, and the screen returns to the original screen" 　Other watches often have things like "region selection," "year display," "month display," and "12H or 24H selection" flashing first. This one has the "seconds display," which needs to be corrected daily, flashing first, and you can correct only that. 〇 No box or instruction manual. Only the main body is for sale.
