Angular Momentum Dive-Tec/500 Watch

The release of a true diver's watch is a stepping stone for most watch companies. The majority of serious watch makers today have at least one diving or nautical watch model. The ubiquitous Rolex Submariner, the luxurious Patek Philippe Nautilus, the historical Blancpain Fifty Fathoms, and the classic yet Modern Breguet Marine are all excellent examples of this concept. Now Switzerland based Angular Momentum meets this need with the release of (arguably) their first serious diving watch specially designed with unique features for ocean depth plummeting.

The new Angular Momentum Dive-Tec/500 is a marvelous tool timepiece with a hip style and is Angular Momentum's ticket to acceptance from a whole new demographic of watch lovers. When combining the non-traditional artistic style of Angular Momentum with the functional needs of a diver's watch, the result is almost a modern classic which offers a total alternative to other modern dive watches. Instead of an overly complex and technical design, the Dive-Tec/500 is a step into refreshing simplicity. The timepiece stresses the four major needs of any diving watch: 1) telling the time, 2) being highly legible in low light and under water, 3) having a rotating diver's bezel, and 4) being able to survive the depths. Everything else is tangential, and probably better provided via other dive equipment. Take for example the mechanical depth gauge of certain luxury dive watches. Would you rely on them for accuracy over a trusted dive computer? Not likely. Instead, a timepiece is more valuable than a dive computer for telling the time. Not from an accuracy standpoint, but rather from a visibility standpoint. Find one dive computer that is as easy to see and read as the Dive-Tec/500. The case is 500 meters water resistant, while the large case and incredible luminant are heaven for under water clouded vision. See the large round screw placed on the bezel? That allows one to secure the bezel so that you do not accidentally turn the hefty ring which is done with 'fresh from the laser-cut' steel. The more raw finish to this component of the watch assists with grip and has an industrial look to it which enhances the watch's style. Other parts of the case are nicely polished.

Details for the Angular Momentum Dive-Tec/500 are impressive. The case is 46mm wide by 17mm thick. In response to the fact that most diving watches are met with salty, not fresh water, the case is made from special 1.4435 NCu StayBrite steel. The higher than 316L grade stainless steel is specially resistant to the corrosive effects of prolonged exposure to salt water. As a matter of style, the crown of the Dive-Tec/500 watch is made in the form of a valve screw - a part found in most manners of life sustaining, air providing underwater equipment. In a brass tone, the crown is actually lemon gold coated steel.


Angular Momentum's ace in the sleeve is their proprietary Èmail Lumineuse luminant. A special formulation created by Angular Momentum, the compound is a mixture of enamel and high grade luminant material. As applied by Angular Momentum, Èmail Lumineuse is a superior luminating material able to sustain a light charge brightly for many hours. The Dive-Tec/500 employs two colors of Èmail Lumineuse for the best possible function and appearance. The compound is applied on the dial of the watch as well as in the bezel (plus optionally on the caseback).

To achieve 500 meters of water resistance, the Dive-Tec/500 uses a 3mm thick sapphire crystal on the front and rear of the watch. The crystal on the back is specially applied over the automatic mechanical Swiss movement, and comes available either clear, or with a layer of Èmail Lumineuse over it allowing for an additional glowing part of the timepiece. The sapphire crystal on the rear of the watch is the access point for the movement and must be removed by Angular Momentum or its dealers if the watch movement requires repair or servicing. The watch will arrive with a silicon or calf leather strap. Price will be around $7,500 with each of the limited production timepieces being manufactured at the Angular Momentum atelier in Switzerland.
