With it's 43.3mm diameter case (excluding crown) the  SSH173J1 is a very comfortable and most of all practical companion. Of course the watch is water resistant to 100m and the beautiful dial is protected by a sapphire crystal with super clear coating. The movement powering all this is the Seiko Cal. 5X83 Solar GPS movement, which is solar powered and extremely accurate. The bracelet has a ceramic center link, which matches the white ceramic bezel.

The Seiko Cal. 5X83 movement connects to GPS satellites, so it automatically adjust to the local time zone, ensuring you are always in sync with the world, regardless of your location.
