·I'm hardly an Omega expert but I do think the Omega you show looks very close to the watch he's wearing.
I can't be absolutely sure but I agree it looks pretty close.
The details do seem to match up. In addition to the overall appearance, lyre lugs and moonphase, there are other features that seemingly line up.
o The roman numeral markers at 8 and 4 are blocky
o The 9 o'clock register looks visually quite similar
o The strap on Senna's watch looks very similar to the Omega original advert shown below (albeit it's the solid gold version).
Also, the Omega Moonphase 175.0034 started production around circa 1990/91, so it's period correct. Still can't be 100% sure, but it's close enough for me to stop digging. In any case, I don't believe it's a TAG Heuer.

In addition, there was another photo that I posted back in Jan 2023 of a watch I couldn't ID (below).
But I have since found other photos that confirm Senna was wearing his prototype 6000 Senna Edition.
The red S being the giveaway.
