On October 8, 2026, British watchmaking brand Apiar officially launched the Carbon1.0 OG watch, billed as the world's first commercial wristwatch with a composite-based additive manufacturing (CBAM) case. The watch combines two additive processes: a CBAM carbon fiber outer case encasing a Grade 23 titanium mid-case, with the titanium case printed by Apex Additive Technologies using laser powder bed fusion (LPBF). The CBAM process stacks ultra-thin woven carbon fiber sheets layer by layer and bonds them at high temperature, with polymer powder melting into the carbon fiber to form the part, producing visible directional layer lines and enabling geometries not achievable with traditional forged carbon processes. The watch measures 40.5 mm in diameter and 9.2 mm thick, houses a La Joux-Perret G101 automatic movement (68-hour power reserve), and is priced at $1,800 for the standard version and $2,080 for the upgraded version (including a 3D-printed titanium buckle), with the order window open for 6-8 weeks until the end of October. Most manufacturing is completed in the UK: case additive manufacturing takes place in Ebbw Vale, Wales, and five-axis CNC finishing is handled by Silvey Engineering. Apiar has previously launched several watches using titanium additive manufacturing and generative design, and this time differentiates its product through materials and geometry rather than timekeeping precision. Value for powder buyers: (1) Demand for Grade 23 titanium powder in consumer luxury watches validates the cost feasibility of metal 3D printing for small-batch, high-value-added products; (2) The combined CBAM and LPBF processes provide cross-sector order leads for powder and composite suppliers; (3) Watch-grade parts have high surface quality and dimensional accuracy requirements, and entering this supply chain requires the capability to supply small batches of stable TC4/Ti-6Al-4V ELI powder.
