Maybe it's out their league, and if no Sports Direct/House of Fraser TV resurrection, but one place the former IW watch floggers/sellers/presenters could go is V-Channel, which is on Sky, Roku & online.
V-Channel
Roku provides the simplest way to stream entertainment to your TV. On your terms. With thousands of available channels to choose from.

But afaik they sell real, proper medium to higher-end watches, e.g. Seiko, Bulova, Carrera, etc. Seem to be a USA channel, but have seen UK presenters, maybe a UK/USA-based hybrid?
I occasionally watch V-Channel on my Roku box for the watch channel, (never bought anything though) and has a music video channel with lesser-known acts, but sometimes surprisingly good tracks!
