Recently back from a one-month holiday in Malaysia. My brother bought an amazing new and totally genuine Swiss Tissot watch there.
First, press the winder for a second or so and then touch the crystal at the 2 o'clock position and the watch forecasts the weather; touch at the 4 o'clock position and the watch tells you the altitude; touch at the 6 o'clock position and the watch tells you the temperature; touch at the 8 o'clock position and the watch becomes a stop-watch; and, darn, I forgot what it does when touched at the 10 o'clock and 12 o'clock positions (my brother's away right now).
Honestly, this is not a wild attempt to wind you up (no pun intended) The watch genuinely does exactly what I've described, except that I may be confused about the watch's actions at each crystal position.
Even the guy in the watch shop at one of Kuala Lumpur's amazing shopping arcades was very excited about the watch and we flipped when he demonstrated it!
