Also – with the bluetooth version would incorporating phone transmitted information like caller ID and battery power be overkill? If we’re going for a slick futuristic piece of wrist gear why not squeeze in every bell and whistle you can? My car has bluetooth phone tech and the radio displays caller ID for incoming calls, phone battery power and call timer. I know you have very limited room in the watch to work with but if the mobile phone broadcasts all that why not have the watch able to display some or all of it?

A suggestion about the line segment indicators… With 12 line segments for the hours (1Hx12) and months (1mX12), it can be difficult to figure out the exact number with some of the middle-range numbers. So perhaps consider making every 3rd or 4th segment longer. If you do every 3rd segment, then you can make the 3rd and 9th segment a little longer than the rest of the segments, and the 6th segment a little longer than the 3rd and 9th segment.

Similarly, for the 1dX9 and the 5mnX9, consider making the 5th segment a little longer. It would probably help a lot when making a quick glance at the time.

Though a suggestion, perhaps have two versions, one with and one without the bluetooth connectivity so that one will be cheaper and have a longer battery life.
