The Apple Watch has been a must-have product ever since it went on sale in April. Now Black Friday has come around, the luxury wearable is getting even more desirable, with retailers slashing their prices on a range of different models.

Although Apple itself doesn't take part in Black Friday, many other websites and shops selling its products do. We've rounded up some of the best Apple Watch deals for Black Friday 2015.

6% off all models of Apple Watch and Watch Sport

Apple specialist KRCS is offering 6% off all models of Apple Watch over Black Friday weekend. This doesn't include the super expensive Edition models, which start at £8,000, but includes the entire Sport and Watch lines. It may not be as big of a discount as others, but few other retailers are knocking money off the more expensive models like KRCS is. The website has been struggling to stay online this morning, but don't worry, because the company says it will honour its Black Friday prices even if orders are placed when items are out of stock - this will be the case until the end of the weekend.

Apple Watch for £24.92 per month over 12 months

While it isn't offering any discounts, Apple is providing 0% finance for 12 months on purchases over £99. This offer will be in place until 5 January, so if you want to pay for your Apple Watch in installments, this is how to do it. Just pick the option at checkout and you're good to go. You may be subject to a credit rating check before being able to complete this purchase.

Free two-year Apple Watch warranty

As always, John lewis is offering a free two-year warranty on all electricals, including the Apple Watch. Apple only offers one year, so getting the extra year for free from John Lewis - which sells the Watch range for exactly the same price as Apple - is well worth considering.

There's always eBay...

And finally, you could always try looking on eBay. Looking at Apple Watch auctions with Buy It Now prices, we've found a range of 38mm Apple Watch Sports for between £220 and £250, while the 42mm also costs around £240 to £300.
