With that in mind, Apple and its retail partners are looking to reduce inventory of the older Series 4 to make room for the Series 5 (the Series 3 remains in the lineup at a discounted price). Amazon is offering some pretty nice discounts on the Series 4, with biggest discount going to the 44mm GPS + Cellular model (aluminum). The watch normally retails for $529, but Amazon is currently discounting it by $129, dropping the price to $399.97. If you prefer the stainless steel body with sapphire glass instead of the aluminum body and Ion-X glass, you can get $100 off that model, making it $649.
If you don't need cellular access for making calls when you don't have (or need) your iPhone on you at all times, the retailer is offering the 44mm GPS-only model which is discounted by $79 taking its price to $349.97.
Most other members of the Series 4 family are discounted by between $50 to $60 depending on body material, color, and watch band type.
We should mention that unless you absolutely can't live without the low-temperature polycrystalline oxide (LTPO) always-on display and the addition of a built-in compass of the Series 5, you'd probably be better served taking the discount on the Series 4.
The Apple Watch Series 4 is powered by Apple’s S4 SoC and incorporates a built-in ECG for detecting heart arrhythmia and fall detection, which can dial emergency services automatically if you take a tumble. Apple says that the Series 4 is rated for up to 18 hours of battery life.
