The power reserve indicator is both functional and poetic—a watchmaking complication that acts like a fuel gauge for time. It gives the wearer a clear reading of the movement’s stored energy, while also offering a window into the living mechanics beneath the dial. With every arc of the indicator, you witness not only the passage of time but also the pulse of craftsmanship. Strengthened by a carbon fiber bezel and paired with a quick-release FKM rubber strap, this Tsar Bomba merges mechanical artistry with modern materials for an unmistakable statement of style and resilience.
