Speedmastere med teksten "and only..." er modell nr 3573.50. Det stemmer nemlig ikke helt at Speemaster er "the only watch...", da astronauten Dave Scott brukte sin Waltham:

142:14:22 Scott: "Verify cabin at 3.5." Okay, cabin's at 3.5. Suit circuit's locked up at about 4.4. My PGA is coming through 5 and decaying. And let's slip on a watch.
[Dave may have had his watch hanging from the instrument panel and, in any event, he is now putting it on and is probably starting the stopwatch function.]
[Scott, from a 1996 letter - "I do not recall ever having looked at my watch after egress. In the cabin after EVA-2, I noticed that the crystal of my Omega had popped off sometime during the EVA. Therefore, on EVA-3, I used my backup watch (which was) of a similar type. It worked just fine during the even higher temperatures of EVA-3."]
[In Dave's 1996 letter to me, he said that the back-up watch was a Waltham. After further researching the issue for an article on watches, Dave wrote in early 2014, "Frankly, back in 1996 I just made a mistake -- it was a Bulova, not a Waltham. When you asked in '96, things were a bit hazy after 25 years, and I hadn't fully researched many of the ancillary parts of the mission. However, more things are coming into focus these days as more people are researching Apollo." Dave has documentation that tells us that the backup watch he wore on the lunar surface was a Bulova Chronograph, Model #88510/01. The Part Number on the wrist band was SEB12100030-202.]
Dette var ihvertfall noe av det jeg klarte å finne frem vha Google (som er din venn).
