The Ball Engineer Master II Diver Chronometer DM2280A-S1C-BKR is a Swiss automatic tool watch designed for professional-level performance, making it a strong option for UK buyers who value durability and technical precision. It features a 42mm stainless steel case with a thickness of approximately 13.5mm, giving it a solid yet wearable presence on the wrist. Inside, it is powered by the Ball RR1101-C automatic movement, a COSC-certified chronometer operating at 28,800 vibrations per hour with a power reserve of around 42 hours, ensuring reliable and accurate timekeeping for daily use and more demanding environments.
This model is particularly notable for its dive-focused functionality, including a bi-directional rotating sapphire internal bezel that can be adjusted via a crown at 2 o’clock, even underwater, allowing precise timing of dive intervals or safety stops. The black dial is equipped with Ball’s micro gas tube technology across the hands, indices, and bezel, providing continuous illumination in low-light or dark conditions without needing external light charging—an advantage for UK divers, travellers, or night-time use. A scratch-resistant sapphire crystal with anti-reflective coating protects the dial, while a magnified date window at 3 o’clock improves everyday legibility.
In terms of robustness, the DM2280A-S1C-BKR is engineered to handle extreme conditions, offering water resistance up to 300 metres (30 ATM), anti-magnetic protection up to 80,000 A/m, and shock resistance rated to approximately 5,000 Gs via Ball’s Amortiser system. It is typically fitted with a stainless steel bracelet and folding clasp for secure wear, and includes a screw-down crown and Mu-metal shielding to further protect the movement. Limited to around 1,000 pieces, this reference combines professional dive-watch capability with Ball’s signature illumination technology, making it a compelling collector-grade option for UK enthusiasts seeking a rugged, chronometer-certified mechanical watch.
