Apple Watch Series 12 models with ceramic cases exhibit physical size differences compared to their aluminum and titanium counterparts. The ceramic versions are slightly taller and wider than the same nominal watch size in other materials. Specifically, the 46mm ceramic model measures 47mm by 41mm, while aluminum and titanium are 46mm by 40mm. Similarly, the 42mm ceramic model is 43mm by 37mm, versus 42mm by 37mm for aluminum and titanium. The thickness also increases slightly for the ceramic models, by 0.15mm. Notably, the display size remains consistent across all material options for each nominal size. Ceramic Apple Watch Series 12 models are also significantly heavier than aluminum and titanium versions. The increased dimensions and weight are attributed to the unique properties of the ceramic material. This marks a departure from previous ceramic Apple Watch Edition models, which shared case dimensions across materials. Ceramic returns to the Apple Watch lineup after a six-year absence, last seen on the Series 5. The ceramic Series 12 is priced at a premium, starting at $899.
