The LAD Weather Sensor Master arrived today. I'm disappointed that the strap is scratched up due to the cardboard packaging through which they put the strap. They should have put plastic around the strap (or the whole watch) to prevent this, like Casio does with Pro Trek models that come in a cardboard insert inside a wooden box.
I also noticed that there is a small scratch on the crystal, even though it was covered with a plastic protector, and there is a scratch on the bezel. Both of these scratches are easily visible in bright light.
As cal..45 noted, the display contrast is pretty bad. It has black digits on a greenish background. The contrast is far worse than on any of my Casios. In bright indoor light, it looks much worse than the picture above. If you made the blue-tinted rectangle on the G-7700-1 twice as dark, this might approximate the contrast of the Sensor Master.
The sensors seem to work okay so far. I adjusted the barometer slightly to match my local NOAA weather station's value, but corrected for my altitude. I also set the altitude properly for my location. The watch can show sea level pressure, but only for the one-hour data collection increments. I haven't found a way to show the current sea level pressure if it's far past the top of the hour. According to cal..45, the watch has an automatic altitude lock. I wish Casio would add an altitude lock and sea level pressure to their ABC watches.
Due to the scratches and the very poor display contrast, I'm leaning toward returning the watch.
