I have used this watch for about a month.  I bought this watch because it was waterproof and inexpensive.  Prior to this, I had a combination digital/analog diver's watch.  The LCD display on this watch has a black background with light yellow numbers.  It is impossible to read looking straight at the watch.  The backlight does not help unless the room is very dark.  The crystal scratches easily.  The calendar only has months and days.  I do not know what happens at the end of the year.  Hold one of these in your hands before you buy one.  The name of this watch is misleading.  It is light and cheap.  I will be happy when the battery goes dead, and I throw the beast away.
