They're probably the most capable smartwatches on the market, but deals on the Apple Watch Series 5 are notoriously difficult to find. 

If you don't want to bundle it with other products, or buy the cellular model on contract, looking for discounts can seem futile.

That's why the deal BT is offering is so attractive. For a limited time, get £20 off all models of the Apple Watch Series 5 when you use the code 'APPLE1WATCH20' at checkout. This means the 44mm Alumium version is just £409, while the cellular model of the same device is now £509

What's more, BT is offering free delivery on all the watches. This comes as part of the company's January sale, so we'd expect it to expire come the end of the month.
