Product Details

New Gradient Dial and Bezel

The new Hanhart Aquasphere Ocean Fade is the latest model in Hanhart's quickly evolving dive watch collection.  This watch features a special gradient dial which transitions from a vibrant blue to a deep black.

Notably, this watch is available with a blue ceramic bezel insert.

Designed to be worn by professional freedivers, the Hanhart Aquasphere Ocean Fade's 42 mm case is water resistant to 300 meters and features a helium escape valve.

Powering this watch is the automatic Soprod P024 (38 hour power reserve) with upgrades like a Glucyder balance wheel and Incabloc® shock protection.  As a true three hand calibre, there is no "ghost" second crown position.


Ocean Fade
Fabio Tunno

Hanhart intentionally refers to this "Ocean Fade" dial as black/blue rather than the other way around.  For a freediver, this color transition represents the first appearance of precious sunlight during the ascent.  It is one of the most significant and memorable parts of every dive.

On the gradient dial, the skeletonized hands and matching appliques are complemented by a bold "12" and a highly legible red tipped seconds hand.  The minutes and seconds can be found etched into the interior bezel surrounding the dial.

The Hanhart Aquasphere Ocean Fade features a unidirectional 60 click bezel with a blue ceramic insert and a red indicator.  

The solid steel case back features a special underwater etching with both matte and polished surfaces.


Tested by Germany's Deepest Freediver
Fabio Tunno
Fabio Tunno is an exceptional athlete in every respect.

At the Freediving World Cup in Sharm el Sheikh, he set five German national records in freediving and is considered one of the best professional freedivers in the world.

Reaching an impressive depth of 110 meters, he is Germany's deepest freediver and regularly participates in world championships.

Fabio tested the Hanhart Aquasphere and used it to dive 110 meters off the coast of Egypt.  He had the following comments:

"As a professional scuba and freediving athlete, I have to be able to rely on one thing 100% of the time.  The Hanhart Aquasphere has supported me perfectly as a coach and athlete at competitions this year.  While diving on the picturesque reefs in the sea or in the depths of the local lakes, I can simply read off my dive times.

For me, it's a must have for anyone who has a passion for diving, a piece of the Black Forest in the distance and vice versa."


Engineered for Depth

The Hanhart Aquasphere Collection is designed specifically for freediving.

A helium escape valve is located at 10, which enhances the watch's functionality for extreme diving depth.

Without a helium escape valve, the internal pressure can build up during deep sea dives. The valve allows the helium to escape safely, preventing any damage to the watch.


New Rubber Strap

This watch ships on either a blue or black rubber strap, paired with your selection of either the blue or black ceramic bezel.  

Designed specifically for the Aquasphere, this new Hanhart rubber strap offers an integrated fit with no gaps between the strap and the case.  It is made from FKM (Fluorine Kautschuk Material) rubber which offers increased resistance to chemicals as well as extreme temperatures. 

The Hanhart logo is embossed across the top of both sides of the strap, and the stainless steel deployant buckle (also featuring the Hanhart logo) offers a comfortable fit while making it simple to put on and take off the watch.

Those with wrist sizes above 7.5" should request a long length strap in the comments box found the end of the reservation checkout process.


Additional features of this watch include:
  • Ceramic blue bezel insert with C1 GL X2 SuperLuminova
  • Soprod P024 with Glucyder balance and Incabloc® shock protection
  • Convex sapphire crystal with interior AR coating
  • Blue dial with C1 GL X2 SuperLuminova on hands and appliques
