The Luminox Bear Grylls Survival XB.3729.NGU embodies rugged practicality and survival-ready reliability, a timepiece built for the adventurous, the prepared, and anyone who demands performance under pressure. Its 42mm case is crafted from Luminox’s proprietary CARBONOX™-carbon composite, exceptionally light, hypoallergenic and highly resistant to impacts, corrosion, and the wear of demanding environments.
Set within a unidirectional rotating bezel (with a diving-zone count-up insert in black and orange) and topped with a hardened mineral crystal, the XB.3729.NGU features a dark, legible dial marked with bold Arabic numerals and luminous hands, minute and second markers, all enhanced with Luminox Light Technology (LLT). This ensures a constant glow for up to 25 years, granting clear readability 24/7 without needing external light sources.
Powering the watch is a Swiss-made quartz movement (Ronda 515), offering dependable timekeeping and a long battery life (around 50 months). A date window at 3 o’clock adds everyday practicality. The black rubber strap (24 mm lug width) paired with a secure stainless-steel buckle balances comfort with durability, ideal for both field use and daily wear.
Built for serious conditions, the XB.3729.NGU offers water resistance to 200 metres (20 ATM), a screw-down crown with double security gasket and protective crown-guards, and a screw-in 316L stainless-steel case back ensuring integrity even under pressure, moisture or dust.
A Watch for the Prepared and the Resolute
More than just a watch, the XB.3729.NGU channels a survival-ready ethos. Emblazoned with the motto “Never Give Up,” it’s crafted to support diving, outdoor adventure, and urban commutes alike. Rugged yet wearable, reliable yet resolute, it’s a trusted companion for those who value function and resilience over flash.

- Handling or clearance fees from the courier.
These charges are set by your country’s customs authority and are payable by you before delivery.
You’ll be contacted directly by DHL with a secure link to pay any applicable charges. Once cleared, your parcel will be released and delivered promptly.
