This Nethuns Scuba 500 Steel is a concentrate of mechanical technology backed by a unique style and design. In addition to being a Limited Edition, it is a piece that is no longer for sale on any other platform because all units were sold a long time ago to collectors and watch lovers With a robust case 16 mm thick by 41 mm in diameter (with a 42mm bezel) and an exceptional waterproofness of 500 meters, this timepiece will please fans of fine watchmaking. This spectacular seal can be achieved thanks to two elements that are both technical and indispensable: a helium valve and a screwed crown. – The helium valve is located at 9 o’clock. This allows the gas to escape when the watch rises to the surface after undergoing pressure from the depths. – The crown is located at 3 o’clock. Once sighted, it ensures a total waterproofness to the timepiece. Under the hood, there is a Japanese caliber NH35 from the Seiko manufacture. Resistant and precise, it has 24 jewels and offers a power reserve of about 40 hours. Its great quality is that it has two modes of pumping: automatic of course, but also manual, thanks to the crown to the right of the box. Fans of precision will also appreciate the stop-second, allowing the second hand to stop once it is pulled a notch. This movement also has a date complication at 3 o’clock, very practical everyday. Everything is carefully protected by a 4.8 mm reinforced sapphire crystal, which also has an anti-reflection treatment. This crystal domed type, which gives it a very vintage look.
