Different refs I would suggest. There are many (dozens of?) Triple Date variants. The date hand changes too. Note on the Mk40 style black dial version it is an airplane, in the blue dial above it is not, more a half moon. Note the number of numerals on the 24hr dial changes dramatically too, from 4 to 8 to 12. In short, they vary a lot!
I think it depends on the model you have, my bluesy and Cosmos have different shaped 24 hr hands, but later models of the bluesy went to the same hand in chrome/rhodium?
The bluesy was also released with the solid white hands too, the watch is beautiful but the hands suck.
