Buying advice for Algeria

Both Apple Watch Ultra 3 and Apple Watch Ultra 4 are sold in Algeria, but they fit different priorities.

Apple Watch Ultra 3 is 25% cheaper at 189,600 DZD versus 252,000 DZD for the Apple Watch Ultra 4, leaving room for accessories or a longer screen-protection plan.

Apple Watch Ultra 4 packs a 631 mAh battery, which translates to longer screen-on time when you are away from a charger.

Above 100,000 DZD you are paying for the chipset, camera tuning, and long-term software support, so weigh those against price.
