Built for Extreme Performance

The forged steel case is engineered to improve durability by re-aligning the metal grain structure, eliminating weaknesses found in traditional cast cases. This results in a stronger, more resilient watch designed to handle real-world impact and stress.

A bead-blasted finish improves resistance to scratches and wear, while an anti-fingerprint coating keeps the case looking clean during daily use.

The upgraded sealing system, including double Viton® gaskets and a threaded crown, ensures reliable protection against water, dust, and extreme conditions—tested beyond its 200m rating. (LÜM-TEC)

Comfort and Everyday Wearability

Despite its rugged construction, the Combat B70 is designed for comfort. The curved lug design allows the watch to wrap naturally around the wrist, making it wear smaller and more comfortably than its dimensions suggest.

Includes two heavy-duty nylon military straps built for durability, security, and all-day wear.
