Omega is technically on the same level as Rolex; my old Watchtimes suggest Omega’s chronometric performance is even better, but Rolexes watches are thinner and, in my opinion, they are going to provide a slightly better user experience for the average wearer over twenty-plus years. Much respect to Rolex, they are truly the best. My dad has a Blue Milgauss, love the watch. It’s a Rolex with some quirk, but it wears perfect and it’s reliable and it looks great on his wrist.
Me though, I like oddities and don’t mind certain flaws, as long as the dial looks right. These are mechanical complexities and they sometimes aren’t perfect. We all risk failing if we venture out of our comfort zone and so failure is more common with high complications or independent novelties. So if my watch is ambitious and creative, but flawed, I only ask that the service department be respectful and considerate - there’s an aloof attitude amongst some brands that is a turnoff.
Specialist houses can’t achieve the same results as Rolex and Omega, even when they have theory on their side, because the best machines produce the parts with tightest tolerances and the robots deliver optimal lubrication to each part. We know who wins the precision war, but there are many more reasons you might choose to emotionally invest in the hobby. It’s perfectly okay to prefer fussy oddities over dependable stalwarts, to have a collection of weird toys.
