for a piece that wasn't destined for the market! And yours would seem THE example to pounce on had I the ready cash. This post, though, may just inspire me to finally put up for sale a number of pieces that should have gone long ago.
One question, though, as I forget exactly which ETA movement resides within. Does the chrono-minute hand move continuously, or does it snap to the next minute after the chrono-seconds hand passes 12 o'clock, as is the case with Omega's cal. 1863 in my Speedmaster?
Good luck with your sale! Wish that I could help out! FH
