@missF thank you for sharing a very interesting article. I'm in agreement with lots of the comments above, won't specifically tag them since it will result in a big reply of "@s", and even before I write this reply I know it might be waffle with no end, but here goes...
I agree with several comments above that I don't think "entry level" - which I take to mean "cheapest watch" - defines a brand. Instead there's a distinction between "entry level" and "entry point" into a brand. I agree with the views above that entry point tends to be a brand's most iconic/recognizable watch, the one which draws people into the brand, and in most cases the one the brand tends to market as such.
But what a brand does with that information is an interesting thing. Omega tend to squeeze the Speedmaster for everything it's worth in terms of model variants and typically they're freely available to buy. Patek Philippe seem to actively downplay their Nautilus in an attempt to not end up as a one-trick pony. Rolex exploit the desirability of the Daytona as a means by which to sell their more expensive pieces, in a usually fruitless attempt to buy what is one of their cheaper watches.
One then considers whether that entry point is a "one and done" with the brand or whether it leads to broader purchases with the same brand. I suspect it's a 50/50 call. For example if I bought a Tag Heuer Monaco it would be the former because it's iconic but really the only model of interest for me. With others you become accustomed to the build quality, style etc. and so make repeat purchases. Without straying too far into marketing/branding, one may also become engaged with the company's "philosophy", whatever that means.
It's not lost on me that the above brands (and most that have been discussed on this thread so far) tend to be at the higher end of the scale cost-wise. While they all have some core models, I'm not sure Longines, Hamilton, Oris etc. quite have a defining watch in the same way. Maybe the need for a broader mass market appeal at the different price point has an inverse relationship with the marketing of one or two iconic pieces. This may of course just be because I'm less familiar with these brands though...
What does this mean for CW? I'm certainly caught within the group targeted with your original question, only having become more familiar with CW just over a year ago. It wasn't actually the Bel Canto that led me to the brand, it was the C60, but I would suspect for the vast majority of newcomers these days it is indeed the Bel Canto that's now the entry point. Maybe even new forum membership and new member posts on this forum attest to this.
The question or issue I see is whether the Bel Canto is a "one and done" watch or whether it does generate interest across the rest of the collection? It's certainly different from the rest of the models on offer. Maybe the Bel Canto is atypical in the sense that the other entry point watches I have quoted above don't tend to be at the upper end of a brand's price points whereas the Bel Canto is at the upper end of CW's offerings. It might indeed have a trickle down effect, or maybe having this "iconic watch" pushes CW generally towards the upper end of "affordable luxury" and into a slightly different price bracket on average, as more recent releases might suggest.
To conclude my ramble, one thing I have observed (in large part thanks to the informative
Show us your early CWs! thread) is that there has been a
huge variety of CW watches. I have a sense of a brand trying to find its true identity in terms of the ranges on offer and the spot it wants to occupy in the market. This may be because I am unfairly comparing 20 years of history to a snapshot in time, but today as I browse the website I find the ranges on offer to be quite tight and well-defined. I think this helps in the appeal as people hunt for their second or third CW watch "post-Bel Canto".
Best,
TB
