Apple has refreshed its lineup of refurbished products, prominently including the Apple Watch Ultra 2 in a sleek black titanium finish paired with a black Ocean Band. Priced at $679, this option offers a substantial 15% discount off the original retail price. Each refurbished model undergoes stringent quality assurance tests and is backed by a one-year warranty, with the flexibility to extend coverage. Notably, due to ongoing patent disputes, the blood oxygen monitoring feature on this model remains unavailable in the US market. Furthermore, the new Mac Studio has also been added to the refurbished collection. The Apple Watch Ultra 2 series is tailored for adventurers and extreme sports enthusiasts, boasting dual-frequency GPS and impressive 100-meter water resistance.
