Alsta Alsta Nautoscaph IV ALS 1
Alsta Nautoscaph IV
Like the original Nautoscaph. these pieces feature 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. Lke all Nautoscaph IVs we have outfitted these styles with our ‘Valencia’ beads-of-rice bracelet.
As with all of our Nautoscaph releases, Alsta make all possible technical, safety and performance improvements while retaining as much of the original designs as possible. Your beautifully-styled Alsta timepieces ooze the same romance and charm as the originals. The main differences being; modern-day materials and technology. Like the originals, they are powered by quality automatic movements.
In addition to being manufactured and tested to withstand the toughest conditions, Alsta timepieces are made to be beautiful and elegant in appearance. They can be worn for any occasion from the workplace to when you are dressed that bit smarter.
