- How long do the tritium tubes last?
- Luminox rates the tritium gas tubes for about 25 years of constant glow. They dim gradually rather than switching off, and the watch keeps running on its battery regardless.
- Is it a real dive watch?
- Yes. It is rated to 20 ATM (200 m) with a screw-down crown, which covers swimming, snorkeling and recreational diving. It is not a certified ISO 6425 professional dive instrument.
- How does it compare with the Navy SEAL 3000 series?
- The 3500 uses the same CARBONOX case and tritium lume in a 45 mm case with a cleaner dial layout. The 3000 series is the older, smaller-cased line; the 3500 is the more current pick.
- Does the crystal scratch?
- The hardened mineral crystal resists light marks but is softer than sapphire, so it can pick up scratches with hard use. A screen protector or careful wear helps.
- What is in the box?
- The watch on its rubber strap, a presentation box and paperwork. The battery is already installed and the strap is sized with a standard buckle, so no tools are needed.
- Will it fit a large wrist?
- The rubber strap and buckle fit most wrists, and the 45 mm case is sized for average to large wrists. Very slim wrists may find the 14 mm thickness top-heavy.
