No price reduction. (I will ignore and block comments asking for a price reduction) Set of 4. Batteries are dead, new and unused. I purchased these and stored them in a dark place as part of my collection. The blue and yellow watches have dead batteries. There are only two instruction manuals. Although they are unused, they are several years old and have been stored by a non-professional. I confirmed they worked when I purchased them, but I do not guarantee their functionality after battery replacement. Please understand this before purchasing. Please check the next shipping date in my profile before purchasing. Casio CASIO watch G-SHOCK G-Shock G-Shock G-COOL blue yellow orange green
