If Eddie were to make the watch just for me, here's what I would like: ;-)
• 46-48 mm diameter and as thin as possible (10 mm or so).
• Black or very dark colored dial so the display isn't obvious when it's turned off.
• Two hands (no ticking seconds hand)
• Any numbers on the dial not partially obscured by the digital display (12,3,6,9 are doable, but 1-12 could also work if the dial is large enough)
• Circular flight computer.
• Elapsed time on the bidirectional bezel, not count down.
• PVD or titanium or sand blasted finish, not bright polished.
• Very good lume or no lume, not poor luminous markers.
• At least 24 mm lugs.
The closest similar watch I can think of is a Breitling Aerospace, but larger with the circular flight computer.
I'm not sure about a square version like the B&R, but something like that would allow for wider straps which would be nice. It would also be nice to offer a separate 24 hour module, and if the lugs or case were wide enough that would allow for something much larger than the Breitling module.
Yeah, I know, probably not going to happen...
