This solar watch is equipped with a stopwatch function. A full-scale stopwatch, which can measure in 1/5-second increments with the center hand, is equipped. A solar cell under the dial converts any form of light into “electrical energy” to operate the watch. “Chronograph” means a watch with a stopwatch function.

Great watch, very reliable. I use as my outdoor watch, and for being in the water and have had no problems with it as well as dress occasions.

This, coupled with wear throughout the year, has meant I've never come to them to find they have died. But of course, a battery, even a rechargeable one, does have a finite life span, and Seiko says this is around ten years. So ten years of worry-free accurate timekeeping is what you can expect from these movements.

There's a reason behind Swiss's exclusivity. While both Seiko and Tissot produce exceptional timepieces praised for their designs and accuracy, Seiko has a strong focus on Haute Horlogerie, grand complications, and elegant dress watches. Think of the legendary Seiko 5 SNXS73 and the oblong, timeless SWR053P1.

Very nice overall quality, looks amazing and has a nice weight to it. Although had some trouble setting up the calendar / date, but this was my first time doing so but the instructions it was okay. You won't be disappointed with this watch!
