Watchco are selling kits for £1370 including 1171 and everything else except 565 movement on ebay.
There is also a 1171 bracelet from the USA - £233 in both cases VAT and maybe duty to be paid. I have been looking at these - the
fully assembled Watchco ones seem to sell for £1500 ish.
As regards a strap - I would have thought some sort of rubber would be attractive, and not too costly.
I guess in cost terms you would easily come in less that our aussie chums - good idea!!
