※This item was working approximately one year ago, but has since run out of battery and its functionality has not been confirmed. Therefore, it is being sold as a junk item. The SEIKO V657 is an analog quartz watch that features a 1/10 second stopwatch in addition to the time. SEIKO Water resist 100m means that the watch is water-resistant and can withstand water pressure equivalent to a depth of 100m in a static state. It is not a function for diving to a depth of 100m, but rather a level of water resistance suitable for everyday life, swimming, showering, and various situations on the water such as splashes. - Brand: Seiko v657 - Model: Chronograph - Color: Silver - Material: Stainless steel - Features: Date display function Returns are not accepted.
