Great little watch. Main display is well laid out. Missed opportunity to put the current local time in the top right bubble in the Timer and especially in the Dual Time displays, like the W800h. For my use cases, having the time in the stop watch bubble instead of 1/100s of a second would be more useful. Few Casios give minutes and seconds the prominence they deserve in the stop watch mode. They should always be the largest digits. One of the few that do is the SGW100.
