Buying advice for Algeria

Both Samsung Galaxy Watch Ultra2 and Samsung Galaxy Watch8 are sold in Algeria, but they fit different priorities.

Samsung Galaxy Watch8 is 44% cheaper at 78,240 DZD versus 140,000 DZD for the Samsung Galaxy Watch Ultra2, leaving room for accessories or a longer screen-protection plan.

Samsung Galaxy Watch Ultra2 packs a 800 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.
