finally got a nice mk3 with an original enicar beads of rice band. I think the mk3 is probably the best looking sherpa graph. I like the black one like with white subdials, i think its the easiest to read. my mk1 jet graph with silver tin pie subdials is very hard to read in most lighting conditions. i think the mk3 with white dial and silver subdials is probably the best looking of all, but dont see them very often. I even like the mk4 with white and silver subdials. i think the mk4 white dials are much more common, but still a nice looking watch. I see them on C24 for 15k and i dont see see them moving at that price. i would think 8-9 k would be the right price for a good one.
