The Luminox Scott Cassell Deep Dive (model XS.1553) is a Swiss-made professional diving watch built for extreme conditions. Designed in collaboration with underwater cameraman and marine conservationist Scott Cassell, it features a 45mm CARBONOX case — Luminox's proprietary carbon composite material that is lighter than titanium and harder than stainless steel. The solid case back and screw-down crown ensure a water resistance rating of 300 meters (990 feet), making it suitable for serious diving.

The blue dial is equipped with luminous white and yellow hands along with circle hour markers and minute markers around the outer rim. A date display sits at 3 o'clock. The watch runs on a battery-operated Swiss quartz movement and is protected by a scratch-resistant sapphire crystal. A uni-directional rotating dive bezel adds an additional layer of dive timing functionality. Luminox's signature self-powered Tritium gas tube illumination system (LLT — Luminox Light Technology) provides 25 years of constant illumination without requiring a button press or external light source.

The watch comes fitted with a dark blue rubber strap secured by a tang clasp. It measures 15mm in case thickness and accepts a 24mm strap width. Swiss Made.
