Buying advice for Algeria

Both Apple Watch Series 12 and Apple Watch Ultra 3 are sold in Algeria, but they fit different priorities.

Apple Watch Series 12 is 34% cheaper at 126,000 DZD versus 189,600 DZD for the Apple Watch Ultra 3, leaving room for accessories or a longer screen-protection plan.

Apple Watch Ultra 3 packs a 599 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.
