Review: Nice watch! - Yes, I love this watch and having a splash of colour on me, to show I'm not grey inside, I am strong and red is a colour associated with sexuality often. I hesitated writing a review because I may not want other men wearing the same watch as me, but hey ho, we are all competing and may the best one win, that if women weren't going for the most expensive watches. Not easy to read the small display in the gym, but not too hard either if there light right above. Easy to count my time between exercises, set it to 1' 30" or 3 mins and beep at the end. Casual wearing is also great for contrast and colour, jeans, shorts etc. Got some compliments also from close acquaintances, but I'm wearing a fkn red watch, I'm not after their compliments!
Review: Great looking watch - Watch looks great and a typical example of a GShock it is difficult to read at a glance but you get used to it. But great edition to the collection.
