Innovation without compromising legacy.
The Alsta Nautoscaph V - Porcelana
The Nautoscaph V Porcelana features a unidirectional bezel, removing the risk of it being accidentally turned while underwater, which could result in a fatal miscalculation of dive time. It is manufactured and tested to withstand the pressure of depths of 999ft (300m or 29atm). The original Nautoscaph had 999ft on its dial, a touch we loved and therefore kept.
Every component of Alsta timepieces is manufactured in Switzerland, and it is powered by a Seiko NH35A. The watches are assembled, tested and quality-passed in Switzerland. Affordable quality engineering, manufacturing and design will always be a hallmark of Alsta watches.
Like all of our Nautoscaph releases, we make all possible technical, safety, and performance improvements while retaining as many of the original designs as possible. Our beautifully styled Alsta timepieces ooze the same romance and charm of the originals. The main differences are modern-day materials and technology. Like the originals, they are powered by quality automatic movements.
Case CuSn8 Bronze. Almost rose gold in color. Made of approx. 7.7% Tin, approx. 92% Copper and approx. 0.3% Phosphorus. This mix is optimum due to its low impurities making the material more resistant to corrosion. Of course, due to the nature of bronze, each piece is unique in its patination and appearance.
