The watch looks classic and you will get used to the small display after sometimes. The original display size is about 2cm×2cm. The display is of average sharpness and the yellow-green backlight though very well visible, is for about 1.5 sec. These are the ways it saves battery to run for 10 years! But I bought this watch because the STRAP LOOKS REPLACEABLE. No matter what watch you buy, the strap doesn't last for more than 2 years. Runs on a single piece CR2025 cell.
