A Hand-Assembled Masterpiece
An incredible feat of engineering, almost every movement component was designed from scratch in-house, and comes in at less than 1mm in height. When paired with a 0.15mm synthetic sapphire dial and crystal and a brand-new, rechargeable 3.7V power cell from Maxell, the result is a hand-assembled wonder of craftsmanship.
An Impressive History of Innovation
The latest models in the continually evolving line of Eco-Drive One watches are powered by the Eco-Drive Caliber 8826. Each timepiece features a 39mm case just 2.98mm thick, sapphire crystals with "Clarity" coating, 3 bar water resistance, 12 months of running time on a full charge, and an accuracy of +/- 15 seconds per month. The impressive lightweight durability is achieved with Cermet bezels and a proprietary Duratect coating. Available in a blue or black dial, each features a distinctive bezel secured by four decorative screws and an intricate "beads of rice" bracelet.
