The Hammerhead Submarine Limited Edition 

The nuclear-powered Attack Submarine: a silent hunter able to operate at over 600ft in depth at speeds over 25 knots. Its primary mission was to conduct anti-submarine operations, with 21” torpedo tubes to aid its task.

This very special edition of the Zelos Hammerhead consists of a dial that was sliced from an actual piece of nuclear submarine hull steel. This submarine served from 1976 till its decommissioning in 2011 and it was the first of its class.

The hull material was obtained from a ‘plankowner’, Mr Kendal who served on the submarine and was part of the decommissioning crew. As an avid watch enthusiast and owner of a piece of the hull, he has very generously provided us with this material to commemorate an amazing vessel with much history behind it.

In addition to the historic dial material, the case features an engraving of the submarine on its side. The caseback depicts a submarine doing an ‘Emergency Blow’. The usual 1000m depth rating on the dial has also been changed to further commemorate the submarine from which the steel was taken.

There are 80 pieces of this version made and each piece has a serial number on the caseback.

The Hammerhead 1000m Diver

The 1970s. Demand for dive watches swelled along with the rise of sport diving. A dive watch was essential piece of equipment to measure elapsed times before the advent of dive computers. 

Our Design Philosophy

The Hammerhead hearkens to the glory days of dive watches. The distinctive cushion shaped case, once common among many dive watches, has been given an angular facelift. A high double domed crystal tops off the vintage influences for the Hammerhead. 

Case Materials

Ceramics, or Zirconium Oxide to be specific, was chosen for the bezel insert due to its legendary hardness of ~1500 Vickers.

Dial Details

The dial of the Hammerhead was designed to be both functional yet unique. It is made from 2 layers, with the outer minute layer fully coated in BGW9 lume. The top layer is circular brushed for a lovely texture which is emphasized in sunlight. Hour markers have been custom designed to be as tall as possible to increase the depth and visual interest of the dial.
