Hamilton Khaki Navy BeLOWZERO 1000m Auto

Expressive design with a functional core

With a case diameter of 46 mm, the BeLOWZERO is one of the largest watches in the Hamilton collection – and with good reason. The oversized size ensures maximum legibility even under challenging conditions. The matte black case is available in titanium with a PVD coating – extremely lightweight, durable, and corrosion-resistant.

The dial features a minimalist design, with large Arabic numerals at 12, 3, 6, and 9 o'clock and bold luminous hands. A discreet date display at 4 o'clock completes the look. The unidirectional rotating diver's bezel is easy to grip, clicks precisely, and can be operated even while wearing diving gloves.

A screw-down case back and the integrated helium escape valve on the side guarantee professional pressure resistance for deep-sea operations. The sapphire crystal is anti-reflective and scratch-resistant. Whether during a dive or as a statement on your wrist: the BeLOWZERO makes an impressive impression – without compromise.

Mechanics for use under extreme conditions

Inside is the automatic caliber H-10, based on the ETA C07.611, which boasts a power reserve of up to 80 hours. This extended running time makes the watch particularly low-maintenance and reliable—an important factor for professionals who rely on their equipment.

The movement is shock-resistant, operates reliably despite temperature fluctuations, and can withstand even extreme underwater conditions. The watch winds automatically through wrist movement, but can also be operated manually using the screw-down crown.

Despite its solid construction, the titanium material makes the BeLOWZERO surprisingly comfortable to wear – a rarity for watches in this size class. Technically, the watch impresses with its simplicity, efficiency, and durability.

Variants with iconic presence

The Khaki Navy BeLOWZERO is available in several versions – including classic black models with white or blue luminous material, as well as limited special editions with red or beige accents (e.g., the Tenet Edition). The strap selection also varies: From a textured rubber strap with a pin buckle to a solid titanium bracelet, Hamilton offers options for individual wearing habits.

Regardless of the style, the BeLOWZERO remains an uncompromising diving watch with cult potential – for adventurers, collectors and all those who want to not only measure depth, but also live it.
