+ Covert – the best spy watch will always be the one that actually looks like a normal wrist watch and not one that looks like something from out of a movie. The watch will be one that goes unnoticed on the wrist and just appearing to be a normal watch.+ Ease of Use – the best spy camera watch (once sitting on your wrist) needs to be simple to operate. The record on-off switch needs to be a simple one-touch on-off function to avoid mistakes, and failing to get that covert recording needed for evidence.+ Quality of Recording – no spy watch is of any use if the video and audio recording is of poor quality. The secret recording should playback in good quality with the facility to download onto other media such as computer or SD card.+ Recording Time – this boils down to the internal storage of the hidden camera watch. A good watch will have plenty of storage space for longer recordings.
+ Battery – battery power is important as you don’t want the watch to stop recording at that crucial moment.+ Date and Time Stamp – having the date and time recorded on the video, or image - taken by your watch - is important when considering using it as evidence in court.
