What Sets It Apart
Key Features
Sand-Toned DialVintage Palette — Military Time Ring — Arabic Numerals
The black dial with vintage sand-toned indices and hands is the XS.0330’s most immediately distinctive feature — the warm, earthy sand colour creating a high-contrast, vintage-inspired palette unlike any other in the WatchNation Luminox range. Arabic numerals, an inner military time ring, and a date window at 3 o’clock complete the layered, purposeful dial layout.
Ronda 515 — 60-Month BatteryLongest Battery Life in the Range
Powered by the Swiss Made Ronda 515 quartz movement with an exceptional 60-month battery life — the longest of any Luminox in the WatchNation range. Low-maintenance, split-second accurate timekeeping for up to five years between battery changes.
Sea Turtle Shell Case DesignProtected Crown — Structural Outcropping
The 44mm CARBONOX™ case architecture is directly inspired by the biological profile of the leatherback sea turtle shell — a protected crown balanced by a structural opposite outcropping, creating a distinctive silhouette that sets the XS.0330 apart from conventional round case designs. Matte black, 50g, and six times lighter than steel.
LLT — 8 Tubes — 25 YearsConstant Glow — No Charging
An 8-tube LLT configuration of self-powered micro-tritium gas tubes embedded in the hands and key dial markers provides a constant, energy-independent glow for up to 25 years without requiring an external light source — cutting through aquatic depths and total darkness alike.
CARBONOX™ Unidirectional BezelLume Pip at 12 — Elapsed Time
The CARBONOX™ unidirectional rotating bezel provides elapsed time tracking with a luminous timing dot at 12 o’clock for reliable operation in low-light conditions — the matching CARBONOX™ finish maintaining the cohesive matte black and sand aesthetic.
22mm PU StrapDouble-Security Gasket Crown — 100m
A 22mm black polyurethane (PU) strap with 316L stainless steel pin buckle provides a secure, flexible, waterproof fit for swimming and outdoor use. A double-security gasket crown protection system reinforces the 100-metre (10 ATM) water resistance.
CARBONOX™ — 44mm — 50gMatte Black — Robust & Lightweight
The 44mm CARBONOX™ case at 50g is six times lighter than steel, yet remarkably robust, shock-absorbent, and hypoallergenic — the matte black finish pairing with the sand-toned dial for the XS.0330’s distinctive earthy character.
Hardened Mineral CrystalImpact & Scratch Resistance
A hardened mineral crystal protects the dial from the impacts and knocks of active outdoor and aquatic use — durable and clear for a watch designed as an active everyday companion.

The XS.0330 is the Luminox Leatherback Sea Turtle Giant — a 44mm CARBONOX™ case at 50g with a black dial and vintage sand-toned indices and hands, an earthy palette unlike any other in the WatchNation Luminox range.

Powered by the Ronda 515 with 60-month battery life — the longest of any Luminox in the range. An 8-tube LLT configuration provides constant 25-year illumination. The Arabic numerals, inner military time ring, and date at 3 create a layered, purposeful dial. A CARBONOX™ unidirectional bezel with lume pip at 12, hardened mineral crystal, and double-security gasket crown complete the build. Rated to 100 metres (10 ATM).

Sand-toned dial, Ronda 515, 60-month battery, 8-tube LLT, sea turtle shell case, CARBONOX™ 44mm at 50g, military time ring, 22mm PU strap, 100m, and 2-year warranty — the Luminox Leatherback Sea Turtle XS.0330 is the most distinctive and characterful watch in the WatchNation Luminox range.
