This is a nurse's upside-down dial watch. It also has a pulse rate memory. The length with the short chain is approximately 10.5cm, the watch diameter is approximately 3cm, and the thickness is approximately 1cm. The color is tomato red. I purchased it from a major online retailer for 2,290 yen (tax included), but it has been stored unused. It hasn't been long since I bought it, and it is currently running on the included monitor battery.
