 There is also the Timex Beepwear Datalink series, featuring wearable pagers using the Timex datalink platform which also function as electronic organisers.Although there are other watches capable of storing all kinds of data, most had either a small keyboard or buttons, which could be used to input data.The keyboard was tiny, and the buttons had to be pressed repeatedly to select letters from the alphabet, making data input difficult and tedious and decreasing the toughness and water resistance of the watch.
