I'm not sure what case you're trying to make here. First, the space-travelling Snoopy is tied to the chrono hand, so it can only travel one way, no? Also, IMO the case-back complication may be understood as an affectionate take on the original A13 event, not a graphical recreation or literal retelling, so it's really neither here nor there which view of the earth is represented, or how precisely, or whether Snoopy is hovering over the correct region of moon or earth, etc., any more than most moon-phase watches are invested in accurate representations of lunar regions or relevant star fields. I also think it's a stretch to presume that the watch's designer half-assed her/his brief and settled for a cute Snoopy going nowhere in particular among the stars for a completely random period of time that just happens to be 14 seconds depending on where you have Snoopy start and stop, knowing that these cavalier design decisions might frustrate and appal; Moon Watch purists- I mean, really?
Here's what Omega says:
On the caseback, Snoopy appears inside his Command and Service Module (CSM) on a magical hand. When the chronograph seconds hand is used, Snoopy takes a trip around the far side of the moon, which has been decorated on the sapphire crystal using a unique micro-structured metallisation. There is also an Earth disc, which rotates once per minute in sync with the watch’s small seconds hand.
A trip round the far side of the moon. Can't we take them at their word? Snoopy appears in his CSM, and takes a trip round the moon, a journey that is also a knowing homage to one of the mission's best-known historical facts, the 14s, which non-coincidentally was timed on the Speedy Pro that was the basis for the Silver Snoopy awarded bu NASA to Omega, an award for a watch that has been crucial to the survival and success of the brand and for which they are justly proud.
So yeah, maybe the designers were lazy and crap, and maybe Omega has engaged in a purely cynical marketing exercise here and will chortle all the way to the bank. But maybe they also wanted to produce a commemorative watch with an engaging complication without massively adding to the cost and complexity of the watch, that its owners could take or leave. And if so, they seem to have succeeded, IMO.
