trevor also has a really nice aquaracer with the arrow G.
also,
1. The hour markers are aligned in the center of the counters (you can compare pics from other dealers to Trevor) - It's not on the previous verions
See 11 o'clock on the photo below (old watch photo)
2. The Tag Heuer logo has a flatter appearance, collect color, with arrows on the G. (Very gen like) - Previous versions have a very cheap plasticky/bulgy looking logo
3. the 500 M kerning/tracking (spacing between the letters) is correct. - The previous version has the 500 in the 500 M too spaced out the kerning is weird.
4. From the looks the rubber material on the bezel seems to be much higher quality. - The previous version is a bit more plasticky.
make sure you get the SW 220 version for the correct movement look!
