I’m have to take issue with that statement, you may not personally like the brand but they are not of questionable value. I’ve owned a Rolex GMT since 1996 and it’s definitely not of questionable value, it has never let me down and still looks and performs the same as the day I first bought it. I also own a 1965 Air King and that again is in astonishing condition for a 60 year old wrist watch, Rolex are a high quality product made to last, and although far from perfect Brompton has the same sort of design integrity, they are designed to a specific job and they do that exceptionally well.
I have no particularly strong feelings either way about the brand and don't doubt their quality; however in recent years it seems that both new and used prices have rocketed (and apparently collapsed again somewhat) due to people increasingly gaming them as an appreciating investment rather than a timepiece.
This appears to be corroborated by
this video (whole channel is worth a watch IMO - bloke is both informative and entertaining). According to said video the price of one particular model / range (I forget which) has increased by many times more than inflation since the '50s - which to me doesn't suggest good value.
It seems these watches command an excessive premium on account of their brand cache, which doesn't reflect cost of manufacture plus a similar margin to other products - hence poor value IMO. In addition I suspect there are other, far cheaper watches that are capable of similar reliability to a Rolex. Finally their currently-still-lofty prices following a bubble wouldn't fill me with confidence if in the market for one currently.
I suspect that given the examples you own have been in your possession for quite some time, they cost proportionally a lot less than their current market value / the new cost of an equivalent - would you consider paying perhaps several times more for the same item now to represent good value?
I like nice things and am happy to pay a premium for better products if I think they'll retain their value; however the cost of many items seems to have been warped by the economic events of the past two decades to the point where a lot of stuff is IMO simply too expensive / objectively not worth the asking price.
In other news it seems that
Brompton are now conspicuously using AI to generate their website content; which seem.... amateurish

Over time, this part may experience wear and tear. If you notice that the seat post is slipping or there is excessive play, it is recommended to replace the seat sleeve. Doing so will help maintain the stability and proper functioning of the telescopic seat post.
I assume they couldn't justify the wages of a real human to proof-read this since the last sentence is the only part that actually makes sense - describing it correctly as a replacement standard part necessary when the original fails, rather than an accessory to improve the existing system.
At least this seems limited to their spares and they still appear to have proper people writing the prose for their more substantial products..
