Apple Watch Series 9 45mm with Apple Care Warranty

The Apple Watch Series 9 models feature the same stronger front crystal component first introduced with the Series 9, which is more resistant to cracking than prior Apple Watch models.

The aluminum Apple Watch models feature Ion-X glass to protect the display, while the stainless steel and titanium models use sapphire crystal glass. Sapphire crystal glass offers better scratch resistance than Ion-X glass because it is a harder material, which means the models with sapphire crystal models are more resistant to scratching and everyday wear.

All Apple Watch Series 9 models feature IP6X dust resistance for use in environments like the beach or the desert, and they offer WR50 water resistance, rated for immersion in water as deep as 50 meters thanks to seals and adhesives. The speaker, which needs air to produce sound, is the only point of ingress and has been designed to expel water using sound vibrations after exposure to moisture
