check out the gen here.....8001 vs 8005, these Conqs are two different models, I would guess one is newer than the other. The 8005 rep is great, the rep 8001 itself is pretty good too.

As for the bracelet, it looks like there are two styles; one flatter and one rounder, just like the reps, unless its just the lighting.
Personally, I like the dial on the 8005 with the minute ticks. However the 2892s it seems are pretty hard to find nowadays.
