Speculation was that the hand had simply been taken from some other Omega watches known to have such similar hands, just for fun. More importantly, there are not enough examples of this watch being produced at the factory as an Omega, rather than a creative collector playing with Omega parts.

Moonwatch Only, the definitive Speedmaster documentation by Grégoire Rossier and Anthony Marquié, recorded that eventually enough collectors got together to gather 20 examples of the rolex replica watches Ultraman to determine that all 20 were ref. ST 145.012-67. They were all equipped with calibre 321, they were all within the serial range of 26.076.xxx and 26.079.xxx, and they were all produced within the very short time frame of June 1968.
Ultimately, it was Omega itself that verified that the Speedmaster was a specific production piece and that the watchmaker did indeed produce it in 1968.

For those who think that OMEGA fitted the orange chronograph hand to the Speedmaster and called it another Audemars Piguet Royal Oak Replica OMEGA even conducted an in-depth study of the various orange chronograph hands produced during that time period and made it clear that the hand made for Ultraman had a special size and did not appear on other OMEGA watches. In fact, all of the orange hands examined confirmed that they were made to the specific dimensions of the particular watch.
