Once again I’ve been around a lot longer mate, you’re not the first person to go “oh x or y will ruin the reputation of Omega or the Speedmaster or the Seamaster”, you’re about the 3000th. The Costco war, the calibre 2500 debacle, the 3313 debacle, the quartz crisis, the initial Swatch takeover, the sudden upmarket push of the late 2000s, dozens of other events were exactly the same with self described experts predicting doom. I had some guy have a complete mental breakdown over the Tokyo Olympics Speedmasters because he claimed Omega had committed fraud by re-releasing two of his LE watches (Gemini 4 & 35th Apollo). It was all horseshit, rightly or wrongly nobody cared.
Now your prediction that the values will go up now, when there actually are a pile of people being doomers over there being a Swatch Speedmaster, but then… somehow after everyone forgets about it in a year or two and nobody cares anymore it will suddenly do damage is not really sensible to me at all.
What has happened is this, sales of actual Omega Moonwatches has gone up in the short term, boutiques and ADs have seen a significant upsurge in demand for the real McCoy. Over time the people who have MoonSwatches will want to upgrade either when the watches wear out or are no longer appropriate for them (wearing a suit to work rather than jeans). Sentimentality will lead them to a Moonwatch.
TAG Heuer released the plastic quartz F1 in the 80s not long after the TAG takeover and they’ve dined out on loyal customers upgrading from those for decades, it was a hugely beneficial thing for the brand and helped them secure a younger demographic to build off.
I’ll admit when I’m wrong if it happens but I give it a near zero chance as this, from a reputation perspective is far more minor than the vast majority of events Omega has been through even in the last 20 years, really it’s a handful of people who care, they just happen to be loud.
