Agree it’s a nice one. On the red chrono hand - rather than guessing from dial photos, two shots would settle it: the movement (the 1040 is stamped on the automatic bridge, and the serial dates the watch) and the inside of the caseback (should read 176.010). The hands on these get swapped during service more often than dials do, so the movement serial vs. the hand style for that production year is the honest test. Scratches aside, the tritium plots on the dial and the lume in the hands aging the same way is usually a better originality tell than color alone, since colors shift in photos.
Worth checking the pushers too - on the 1040 the chrono feel is distinctive (soft start, firm reset), and a mushy reset is the usual service flag on these.
