DELTAt NBS is a different kind of dive watch. Styled like a heavy industrial machine, the ‘NBS’ takes inspiration from the structure of a nuclear fusion reactor. The exceptionally robust construction of the watch case and the dial fashioned after the nuclear fusion reactor’s core along with exposed mechanical elements give a bold and futuristic appearance.
The NBS watch houses an overall look that combines elegance with robustness, design with practicality and an industrialized look that heavy duty watch wearers will be delighted by. The NBS has incorporated various industrial elements such as the robust casing, three removable screws that run through the bezel, case and outer bottom cover.
The thick straps and metal buckle and loop details work to reinforce the masculine image and robustness of the watch. The Skeleton movement’s balance wheel and escapement fork’s operation can be seen through the three windows of the dial emphasizing the overall mechanical image that the NBS projects, these details packaged finally like a tool kit complete the overall look.
NBS collection is not only elegant, but also practical. Its robust and strong structure, with a 1,000m/3,300ft water-resistance, can withstand almost any circumstance. Even its package, also equipped with an automatic air valve, is highly durable and water-resistant.
The case of NBS is made with 316L Stainless steel, Aluminum bronze or Titanium depends upon the model. Each model is limited to 300 pieces only. Three models in the NBS series (NBS MKI-CRG, NBS MKI-CBG, and NBS MKI-CGG) are made with aluminum bronze.
Aluminum bronze has always been one of the materials that are used for heavy industrial tools, especially for maritime industry. After exposing to water, aluminum bronze will develop a layer of patina. This layer of patina not only protects the watch from erosion, its pattern is unique for every watch, which makes every watch unique.
NBS features a patent pending lug screw locking mechanism. The small rubber O-Ring provided on the lug screw adds extra friction between the screw and the pin when fastened. It helps prevent the screw from loosening, even without the use of screw glue.
NBS series comes with a choice of different dial versions such as Matt Black, Carbon Fiber, Green, Mahogany or Silver depends upon the version. The opening of the dial offers the view of movement parts.
The movement beats inside is Miyota Automatic Cal. 8N24, which offers 40 hours power reserve when fully wound.
