You have to pay attention to what those watches sold at originally. The C60 sold for $795 US on strap ($910 on bracelet). Prices have increased a lot since then. Some of those were snatched up as 'nearly new' then they would could have been purchased as low as $550 ($637 on bracelet). Occasionally they could have been even cheaper. Also take note that for the most part of sales life of these models CW had their voucher codes active which would drop the prices of new watches even further - $125 off a new watch (CW stopped issuing vouchers in Jan 2023 - Kip's announcement was Jan 2, 2023). So going off of RRP isn't exactly right.
Certainly not every model is trading above RRP. The moderators track secondary market pricing in the archive. Note that not all sales are recorded as that would be an impossible task. However it does track a lot of sales. Also note that the prices are averages and don't take into account straps or bracelets so bracelets would probably be a little higher and straps a little lower.
Right now the average for 2024 for the Black C60 600 MKIII is trading at $677 with 29 recorded sales (this includes all 40 mm strap/bracelet variants in black). The 38 mm is trading for a little less on average.
For those models in particular the branding at 9 was very divisive driving the price of these down quite a bit. The C60 300s will take less of a hit because they were never sold under the old voucher and they have a more popular design overall. The 40 mm models are currently trading for about $789 (RRP $850-1050).
Also, we aren't talking about people making a living off of these things but it never stopped people trying to make a few bucks. Even if they didn't sell on the secondary market they were still snatched from the hands of people who really wanted them. Hence the limits.
