I'll try and find the link, was a couple of years ago since i last looked at it, but IW charge approx £14,000 back then for the hire of the studio for an hour, with one presenter. That's for brands like My pension, Emma, Everest, etc, whom IW don't sell direct to the customer but provide the web site address or phone number for Customers to go to, just a glorified advert hour long advert. Of Course the programs are now 45 minute and it's 2 years later so price may be different. But it may give a rough idea as to what sales IW may have to do in an hour to make money. Last night's 90 minute show had 28 different watches (allowing for the different colour variations) on offer, say average price was £100 and if the sold even 5 of each watch, then that's 140 watches at a £100 = £14000, and they probably sold more than that because of an answer to another of your questions, ie there are lots of uninformed mugs out there.
I think they have a lot of folks, new to watch collecting and are collecting these watches, and the other made in China brands, thinking they're putting together a decent watch collection at really affordable price, sure there will be quite a few folks just buying an odd watch for themselves or as a presents, but for some strange reason IW seem to have attracted a mass of new folks to watch collecting, who have little knowledge of watches and all they are learning/ have learned is from IW and their guests. Reading some of the revues, it's quite clear that folks have been taken in by the sales patter and lies on IW and are making up collections consisting of Swan & Edgar, Constantin Weisz, The Resultco brands, CCCP etc etc.
As to how much they make per watch, the first watches Swan & Edgar had on IW were just rebranded Ali Express watches, at least now they have advanced to picking different watch options (case, movement, dial, hands, colour etc) themselves probably through HKTDC, but the wholesale cost will still be similar, at that time they were selling on IW at least 4 times the price of the same watch on Ali, and of course the price on Ali is a retail price not the wholesale price. So plenty of mark up to be split between Fields Luxury and IW so both can make a big profit or make a smaller profit but increase sales by giving bigger discounts from the inflated RRPs.
On Swan & Edgar Site at the moment RRP for this watch is £190.
The Hand Assembled Complexity Automatic is a highly sophisticated timepiece and is referred to as the ‘Clean Sweep’, due to the sweeping second hand.

It's just a rebranded Ali watch, which is £25 retail on Ali (as i say wholesale will be even less, prob nearer £15)

So if I remember that watch sold around the £120/£130 mark originally on IW so plenty of profit to be made.
