Angular Momentum's Dive-Tec/500

Angular Momentum’s first high performance diving timepiece - DIVE-TEC/500

Two-body Staybrite® 1.4435 NCu watch case with barrel shape centered corns. Revolving bezel with „Email Lumineuse“ diving time indexes and 12.00 mm stainless steel fastening screw. Stainless steel screwed in tube with 5.00 mm thread, smal operation crown, large hexagonal brass protection

crown, 20 micr. lemon gold plated. Email Lumineuse „Champlevé“ dial. hour and minute hand with “plique à jour“ Email Lumineuse. Front crystal 3.00 mm bombe sapphire 48.200 ct., back crystal 3.00 mm bombé sapphire crystal 48.200 ct., available in various colors or transparent, leather strap or silicone strap with stainless steel buckle, waterresistant to 500 meters (50ATM), mechanical self-winding movement. Case caliber 46.00 mm x 17.00 mm.

The revolving diving bezel can be easily removed after diving for proper cleaning. The outer „skin“ of the „grip-well“ bezel has a rough texture caused by laser cutting process, which gives every timepiece an unique appearance - like its own finger print.


Angular Momentum has found a new solution for water resistant watch cases.In stead of a screwed on back, the Dive-Tec/500 is built with a back crystal of 3.00 mm bombé ground sapphire crystal of 48.200 ct weight. The crystal is fi xed on the watch case with a Hytrel I-Gasket. The back

crystal can be removed in the Angular Momentum ateliers with a special tool. This simple technique avoids of any water resistance problems which can appear on conventionally constructed watches with screwed in steel backs with rubber O-rings, especially after several years of use. The sapphire back crystal is available in different colors or transparent.


Every DIVE-TEC/500 timepiece is completely manufactured in the Angular Momentum ateliers, piece for piece and not in large series. Therefore small differences appear from piece to piece.

Staybrite® 1.4435 NCu represents a new alloy composition, which has been developed to meet the advanced requirements of the high-end Swiss watch industry. It is a Swiss made stainless steel and is considered the best purest steel which dominate the stainless steel world of today.

Èmail Lumineuse

The Èmail Lumineuse is a recent development of Angular Momentum and a fusion of enamel and a non-radioactive, organic substance which is in the position to glow for many hours after being loaded under light for a period of 10 minutes. The Èmail Lumineuse used on the Dive-Tec/500 is „Aqua Blue“ for the secondary information indexes and hour hand and the quick loading „Pale Green“ for the primary information: indexes dive time and minute hand. The glowing capacity of the Email Lumineuse exceeds those of the the luminous substances used in Horology today by far.
