Saw this earlier but just getting to it now. > I've tried many trackers over the years and most are frankly unreliable. Re: that first reply, I actually gotta disagree about sticking to basic extensions. In my experience, those Chrome plugins are super brittle. Every time Jomashop or Chrono24 updates their site layout, the tracker breaks and you don't even realize it until you've missed the deal. I remember chasing a rare GMT years ago and the extension I used basically died overnight. It was gutting. You think it's watching the price, but it's really just staring at a broken piece of code while the watch sells out. Before I suggest some sturdier alternatives, are you strictly looking for a one-click setup, or would you be open to a visual web monitor? Also, are you hunting for the classic green SARB017 or one of the newer Prospex models? The market for the older ones is way more volatile right now.

Seconded!

I've tried many trackers over the years and most are frankly unreliable. To give you a solid recommendation, are you strictly looking for gray market dealers like Jomashop, or do you need it to handle private listings on Chrono24 too? Also, do you need the tracker to ping you instantly, or is a once-a-day check enough for your timeline?
