The Ball Fireman NECC DM3090A-P10J-BK watch brings excellent features such as high durability and great workmanship. Its versatile design makes it a great tool not only in tougher conditions, but also for everyday wear.The case of the Ball DM3090A-P10J-BK is made of stainless steel with a black DLC finish (TiC technology) and is complemented by a rubber strap. Inside this case, the Ball RR1103 Swiss mechanical automatic movement (based on the Sellita SW200) operates at a frequency of 28,800 semi-frequencies per hour. The movement can be observed through a transparent sapphire crystal. At the traditional position 3 we find the date display, highlighted by a magnifying glass (the so-called cyclops).The watch is also resistant to an impact of 5000 Gs, which corresponds to a drop of up to one metre without damaging the movement. A unidirectional rotating lunette is used to measure the time. In addition to the case design, this is ensured by the patented Amortiser shock protection system (shock protection for the automatic winding rotor, with the option of fixing the rotor on some models). A unidirectional rotating lunette is used to measure time.The perfectly clear dial is protected by a sapphire crystal that is extremely scratch-resistant. An anti-reflective coating provides excellent legibility even in direct sunlight. Readability in the dark is ensured by the H3 tritium luminescent tubes on the hands and indexes. These ensure reliable luminosity regardless of previous illumination, unlike the classic luminescent coating. The water resistance of this watch is 300m and is supported by a screw-down crown, so it can easily handle diving, for example.
