The Ball Roadmaster Perseverer NM9050C‑S1‑BE combines refined Swiss watchmaking with robust, everyday‑ready performance, creating a timepiece that is both practical and striking. Its 40mm 904L stainless‑steel case pairs brushed surfaces with polished accents for a refined yet purposeful look, while the deep blue dial with horizontal texturing adds depth and elegance. Applied luminous indices and polished hands, enhanced with 16 self‑powered micro gas tubes, provide continuous luminescence without needing recharging, ensuring clear readability in all light conditions. The date window at 3 o’clock is magnified for ease of use, and a screw‑down crown enhances water resistance to 100 metres making this watch as suitable for daily life as it is for adventurous days out.
Ball’s heritage stems from the railroad industry, where stringent accuracy was essential for safety. The brand has continued this legacy by prioritising precision, durability and innovative features, such as micro gas tube illumination and patented shock protection systems. Roadmaster models like the Perseverer reflect these values, combining function and timeless design.
Chronometer Precision & Movement
The Perseverer is powered by the Ball Calibre RR1103 automatic movement, a robust Swiss engine based on proven platforms such as the ETA 2824‑2 or Sellita SW200‑1. Beating at 28,800 vph with 25 jewels, it delivers reliable performance with a power reserve of approximately 38 hours. The movement drives hours, minutes, sweeping seconds and a date display, and is protected inside a durable case built for everyday use.
Durable Construction & Everyday Reliability
Crafted from corrosion‑resistant 904L stainless steel, the case and integrated bracelet are both strong and visually refined. A flat anti‑reflective sapphire crystal protects the dial from scratches, while the screw‑down crown and solid construction help achieve water resistance to 100 m (10 ATM). The watch also offers shock resistance up to 5,000 Gs and anti‑magnetic resistance up to 4,800 A/m, enhancing its resilience in daily environments.
Clear, Stylish Readability
The combination of Ball’s micro gas tubes on the dial, hands and indices ensures excellent legibility in both daylight and darkness, glowing continuously for years without external light charging. The horizontal textured dial provides subtle visual interest while maintaining clarity and balance.
A Versatile Everyday Watch
The Ball Roadmaster Perseverer NM9050C‑S1‑BE is more than a timepiece it is a dependable companion built for everyday wear with rugged performance and classic Swiss style. Its well‑proportioned case, durable materials and continuous luminescence make it a versatile choice for both urban settings and weekend adventures.
