Hands on the Mido ref 5907 all have the same combination of dauphine hour and pencil minute. In most all cases both hands are luminous, though a handful of examples have been seen with non-luminous hands, all with white dial and gold hands in the 221xxxx range. Given all seen non-luminous hands were paired with non-luminous dials, I am inclined to believe these are original to the watches.
An old catalog image contains an example with baton hour hand, though I have never seen an image other than in that catalog, and it is unclear whether this hand was ever used in production. This image is unusual in that the watch appears to have been worn, judging from the scratches on the bezel, and the dot on the bezel appears to have some color to it, that is not black…this raises questions to me if the hands are not actually correct in this example.
In general, we see silver hour and seconds hands with black dials, regardless of metres or feet units, although there is one exception we have seen with gold hands, and gold hands paired with white dials, again regardless of metres or feet. Likewise the ‘Mido’ emblem is silver on black dials and gold on white.
The silver seconds hand has a different shape than the gold seconds hand. The silver seconds has a a flat end at the tail, tapers sharply in to the center, then is the same thickness for the long end of the hand. The gold hand in contrast has a pointed tail, expands to its maximum width quickly and then consistently tapers all the way though to the tip.
We also see two other styles of hands, each found on two pieces. One is a sword design for both hour and minute, and the others are straight hands, with flat ends.
I believe the examples with sword hands, found on later Ocean Star timepieces, are replacements (the examples with the sword hands are separated by ~500 serial numbers). The first example has a red bezel dot, is polished, and have dark lume, so reasonable to believe that hands were replaced.
The examples with straight flat ends are separated by ~400 serial numbers, and I also do not believe are original to the watches on which they are found. One example is a project watch in poor condition, so not surprising to have different hands. The second example has a dial that appears to be in good condition, curiously also without a bezel.
