Purchased this watched because of the simple elegance of design, the quality of the brand, its sapphire crystal, all at a very reasonable price. I have not been disappointed as the watch looks great whether on my wrist or when simply placed on a counter top. The chronograph feature, again a simple 30 minute stop watch, measures elapsed time up to 30 minutes within one tenth of a second. Both this function and this watch's primary function of displaying of time are highly accurate... I have had this timepiece nearly one month now and thus far no adjustments/resets needed. No scratches on the crystal either despite my high propensity for doing just that. May not need any kind of reset until the fall when we all set our clocks back one hour.
