Design and Build Quality

The Apple Watch Series 9 follows in the footsteps of its predecessors when it comes to design. It features a sleek, rounded design with thin bezels that maximize the screen real estate. The Series 9 is available in various materials, including aluminum, stainless steel, and titanium. This model also includes a ceramic and sapphire crystal back that enhances its premium feel.

Apple Watch SE

The Apple Watch SE retains the classic Apple Watch look but at a more affordable price. It comes in aluminum and has a slightly less robust build compared to the Series 9. However, the choice of recycled aluminum makes it a more sustainable option for environmentally conscious users. The design features a glass front, plastic back, and aluminum frame, ensuring durability despite its lower cost.

Verdict

If premium materials and a luxurious feel are important to you, the Series 9 clearly stands out. The SE, on the other hand, offers a great balance between design and affordability.

Display

The Apple Watch Series 9 has a stunning Retina display that is always on. It offers a higher resolution and a brighter screen compared to previous iterations. The sharpness and brightness of the Series 9 display make it easily viewable in direct sunlight, which is a significant advantage for outdoor activities.

Apple Watch SE

The SE features a Retina LTPO OLED display that is clear and crisp. However, it doesn’t offer the always-on feature, requiring users to raise their wrist or tap the screen to activate it. Despite this, the display quality is sufficient for most everyday needs and activities.
