The Ball Engineer III Marvelight Chronometer NM9036C-S1C-BKR is a Swiss automatic timepiece that combines everyday practicality with COSC-certified precision, making it a strong choice for UK collectors seeking a reliable daily wearer. It features a 40mm case crafted from corrosion-resistant 904L stainless steel with a thickness of approximately 13mm, giving it a solid but balanced wrist presence. Inside, it is powered by the Ball RR1102-C automatic movement, a chronometer-certified calibre operating at 28,800 vibrations per hour with a power reserve of around 38 hours, ensuring consistent and accurate performance.
The black dial of the NM9036C-S1C-BKR is designed for clarity and functionality, incorporating a day-date display (day at 9 o’clock and date at 3 o’clock with magnification). Ball’s signature micro gas tube technology is applied across the hands and hour markers—typically 27 tritium tubes—providing continuous illumination in low-light conditions without the need for external charging, a practical advantage in the UK’s variable lighting environments. The dial is protected by a scratch-resistant sapphire crystal with anti-reflective coating, while a screw-down crown enhances sealing and overall durability.
Engineered for resilience, the NM9036C-S1C-BKR offers water resistance up to 100 metres (10 ATM), making it suitable for swimming and general water exposure, alongside anti-magnetic resistance up to 80,000 A/m and shock resistance rated to approximately 5,000 Gs via Ball’s Amortiser system. The watch is typically paired with a stainless steel bracelet fitted with a folding clasp for secure wear. As a limited edition of around 1,000 pieces, this reference balances rugged Swiss tool-watch engineering with refined aesthetics, making it a compelling option for UK buyers who want a durable, chronometer-certified watch with strong everyday versatility.
