Although you probably know this by now, the Alsta Nautoscaph Superautomatic was first released in 1970 and was immortalised by the 1975 blockbuster movie ‘JAWS’.  In 2019, Alsta released a faithful re-edition of the watch worn by Oceanographer Matt Hooper, played by Richard Dreyfuss, in the movie.

Like all of our Nautoscaph releases, we 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 of the originals. The main differences being; modern-day materials and technology. Like the originals, they are powered by quality automatic movements.

Every component of Alsta timepieces is manufactured in Switzerland, including a Sellita SW200 movement. The watches are assembled, tested and quality-passed in Switzerland.

Affordable quality engineering, manufacture and design will always be a hallmark of Alsta watches.

Hooper was wealthy but was also a man of science. He demanded truth and relied upon quality of information and methodology in all his findings as opposed to hearsay or taking things at face value. It is no surprise that this man, who could have afforded any brand, chose quality as opposed to brand recognition in all of his diving and research equipment. This included a discerning choice of timepiece.

It was also the obvious choice for us to bring Alsta out of the archives and back onto the wrist.

The Alsta Nautoscaph was immortalised in the 1975 classic movie Jaws when it was the timepiece of choice of oceanographer Matt Hooper played by Richard Dreyfuss.



Alsta timepieces are made to be robust and withstand the pressures of the oceans, the mountains and all in-between.

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.

The Nautoscaph IV has a unidirectional bezel which removes 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 which is 300m or 29atm. The original Nautoscaph had 999ft on its dial which is a touch we loved and therefore kept. We told you that we don’t just follow the herd! The Surf n Ski is also tested to the same limits.


This watch case is cast from 316L marine grade Stainless Steel. Grade 316L is the standard molybdenum-bearing grade which means it has high corrosion resistant properties and particularly high resistance to pitting and crevice corrosion in chloride environments. It is also anti-magnetic.  We do recommend that if you submerge your watch in saltwater regularly or for long periods of time that you give it a rinse under fresh water after submersion.



The Nautoscaph IV crown forms part of a triple-lock mechanism that ensures the water resistance of the watch.


The domed glass in the Nautoscaph is a hardened sapphire crystal. Light scratches are relatively easy to remove by polishing and if the scratches are deeper you can replace the crystal. Our crystals are tested for toughness and contain an anti-reflective coating on the inside to aid clear vision.

We wanted our watches to follow their predecessors by having lovely domed crystals therefore we designed and manufactured them especially in order that they were true to their heritage in design terms. Performance improvements resulted in that the original Nautoscaph contained plexiglass which is more prone to scratching. Also, we decided to remove the magnifying window or “cyclops” above the date in order to reduce the risk of damage to the crystal.
