Thank you for viewing. CASIO SMARTPHONE LINK Series BSA-B100-1AJF Current model With its basic design and color, and its many functions, this is a recommended model that will be useful in various situations! ☆ Purchased in August 2020, this item was used a few times and then sold on Mercari. I wore it about 1-2 times a week for about six months, and then stored it at home. There are some minor scratches and stains, but there are no major issues that would hinder its use. Since this is a personal inspection, there may be some oversights. Please check the photos and agree to purchase. The battery was replaced on December 23, 2025, at an electronics retailer that handles G-Shock watches. (Photo 14) The time and calendar were also adjusted. Product Description (excerpt from the Casio official website) This mobile link compatible model comfortably supports daily exercise and training. A slim case has been adopted so as not to interfere with exercise. Equipped with functions useful for daily health management and sports, such as auto double LED light, step count function, timer that can measure up to 5 sets x 20, and lap memory of up to 200. In addition, by linking with the dedicated app "CASIO WATCHES" via Bluetooth® communication, daily activity record management and exercise settings have been realized. Calorie calculation and target step setting are also possible. Through app linkage, the original functions of the watch, such as automatic time correction, are also pursued.
