The Oppo Watch S features a 1.46″ OLED/AMOLED display with a resolution of 464 x 464 px and a pixel density of 317 ppi. It is waterproof with a 5 ATM rating and an IP68 ingress protection rating, meaning it can withstand submersion up to 1.5 meters. The watch weighs 35 g and has a thickness of 8.9 mm, making it relatively lightweight and slim. It also offers a replaceable watch band but does not include branded damage-resistant glass or a sapphire glass display. The Oppo Watch X2 Mini, on the other hand, has a slightly smaller 1.32″ OLED/AMOLED display, with a resolution of 466 x 466 px and a higher pixel density of 352 ppi. It also holds a 5 ATM water resistance rating but has an IP67 ingress protection rating, offering protection against water up to 50 meters in depth. This model is slightly heavier at 37.8 g and thicker at 11 mm, with a slightly smaller width and height of 43.2 mm. The Oppo Watch X2 Mini includes a sapphire glass display and a replaceable watch band, but it lacks branded damage-resistant glass.
Both watches have a touch screen and are designed for adults, not kids. The Oppo Watch S does not have an always-on display, whereas the Oppo Watch X2 Mini does. The volume of the Oppo Watch S is 18.0225 cm³, while the Oppo Watch X2 Mini has a larger volume of 20.52864 cm³, reflecting its slightly bulkier build. Additionally, the Oppo Watch X2 Mini's waterproof depth rating of 50 m is significantly higher than the Oppo Watch S's 1.5 m, making the X2 Mini better suited for more extreme water activities. Both watches have a replaceable band, but the Oppo Watch S is lighter and thinner, offering a more compact and streamlined design.
In summary, the Oppo Watch S and Oppo Watch X2 Mini differ in screen size, pixel density, thickness, weight, water resistance depth, and other design factors. While the X2 Mini offers a more robust waterproof rating, a higher pixel density, and sapphire glass, the Oppo Watch S stands out with a larger screen and a slimmer, lighter build. Both models have comparable AMOLED displays, but the choice will depend on whether the user prioritizes size, weight, or additional features like the always-on display or sapphire glass.
