This is a great watch. About accuracy: After performing the compass calibration, I can say it is fairly accurate. I always get acceptable direction of where the north should be. Temperature is also accurate but it is true, you need to take off the watch for about 10 to 15 min to get a good reading. If not, then you get a constant 31 degrees.
About size, I think it does has a very good size, big numbers, clear display and very nice to press buttons.
Band is resin.
I gave 4 stars because I think alarm is dim but that is just a personal point of view.
Very nice to use. In all, I am happy with my purchase.

Update  dic 21 08:  Yes, time  is display normally in the central area of the screen, where the 330 is shown on picture. This picture here in amazon shows the compass mode. I have added some images for size and display info.
