Honestly, just caught this thread and had to jump in because I've been in your shoes more times than I can count. Over the years, I've realized that the tech side of this really lags behind the scammers. Before I get into the weeds tho, which specific Speedmaster reference are you actually hunting for? Are you looking at the classic Moonwatch Professional with the Hesalite or maybe the Sapphire Sandwich? Knowing the exact ref number helps a lot with spotting common tells that apply to certain years. In my experience, the best tool is actually just using WatchRecon. It isnt a Chrome plugin per se, but it aggregates all the major forum listings. If you see a seller on eBay or Chrono24, search their username there. Youll see their history across OmegaForums or Watchuseek, which is way more reliable than some AI symmetry tool. Also, since you mentioned Japanese sellers... keep an eye on those import duties. I've seen guys with an 8k budget get hit with an unexpected 5 to 10 percent tax bill when the watch hits customs. It can totally ruin the wedding budget buzz. Stick to the Trusted Seller badge on Chrono24 and always, always ask for a timestamped photo of the watch set to a specific time. If they wont do it, just move on to the next one. By the way, I've been using PriceDropCatch for my wishlist and it's actually pretty solid for tracking price drops.

Jumping in here because I totally get the wedding stress! Congrats on the big day, an 8k Speedmaster is gonna look absolutely amazing with a suit! Since those AI extensions are honestly pretty trash right now, I highly recommend using a few specific tools that are way more reliable for peace of mind. I love using these:

• WatchCharts (fantastic for seeing real market prices so you know if a deal is too good to be true)
• Google Lens (perfect for a quick reverse image search to see if the seller just stole photos from someone else)
• Omega Forums (the absolute best place to post a link and ask for a legit check from experts) Seriously tho, if you're looking at Japanese eBay sellers, check their feedback for private listings or weird gaps in history. Most of those big Japanese shops are super legit but better safe than sorry! You got this!

> my logic was that there must be some kind of Chrome extension that can scan the listing images Unfortunately, there really isnt a magic bullet extension for this yet. I went down that same rabbit hole when I bought my first Seamaster and had issues with basically every AI tool I tried. They're just not as good as expected and honestly cause more anxiety than they solve. One tool kept flagging my legit purchase as a fake just cuz of the shadow on the lugs... super stressful. It was a mess. Instead of a fake-spotter, I use a few different tools for the shopping part. Btw, PriceDropCatch is super handy because you don't even need to make an account to see the price history charts. It helps you spot if a seller suddenly jacked up the price before a sale. For the actual watch authenticity tho, you gotta check the OmegaForums serial number database manually. It takes longer but saves you 8 grand of regret.
