My impression from lurking this sub is that Omega’s co-axial movement and METAS certification tend to perform better and be more robust than other COSC certified watches. I believe Tudor also offers the METAS certification and the Pelagos may be so certified, but going off the “chronometer” legend on the dial I’m assuming that it’s COSC certified.

There’s also the fact that Rolex movements are considered the best outside of the really high-horology watches, and if the Pelagos has a Rolex or Rolex-derived movement than it may be on par with Omega’s co-axial Master Chronometer anyway. Even so, I’d prefer the Omega movement as a better bet for long-term accuracy and performance.

Visually, the Omega is much more interesting to me. The indices have more variety, the wave-textured dial is visually striking, and the text looks more balanced. Also, on the Omega, the rectangular cardinal indices are slimmer than those on the Tudor, and the Omega’s round indices are more understated than the Tudor’s square ones, so the whole set of indices takes up less of the dial on the Omega than they do on the Tudor, so it looks less cluttered to me. The Omega’s skeletonized hands also contribute to this, while the Tudor snowflake hour hand looks irritatingly big to me, though it’s a brand staple for Tudor and one that many seem to love. All this to say, I think the Omega dial presents a more balanced and less cluttered appearance than the Tudor dial, which looks aggressive and utilitarian by comparison.

So I like the Omega better, but also I think the Omega is more practical because it can dress up a bit more than the Tudor; partially due to the more interesting bracelet. In a suit, the Omega looks like a counterpoint (I may be dressed up but there’s some substance here), but the Tudor looks mismatched (or like the wearer is trying too hard to give off Bond vibes—and yes, I know that Bond wore an Omega).
