Montre livrée en Full Set avec boite et notice. Comme toute G-Shock, excellente finition, robuste. Lecture de l'heure aisée. Fonctions basiques mais largement suffisantes. Belle présence au poignet. Le petit plus : montre radio-pilotée avec mise à l'heure automatique en fonction du pays choisi.
Prix plus que correct, livraison ultra rapide.
Un article qui correspond parfaitement à mes attentes.
Je recommande la montre et le site, tout est parfait !

| 19 September 2025 | ++ | Service rating : All good, arrived in time! Product : It is as pictured, and the light works when I press the button. It feels very light, but that's got to be good because I'm wearing a man's watch on a woman's wrist. It looks good. The only annoying thing is it has an audible tick, and I use it as... |
