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.

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!
