Khaki Navy Belowzero Auto Titanium H78535380 Watch

The Watch

Founded in 1892, Hamilton has built a legendary reputation in watchmaking, crafting timepieces that are exceptional in quality, precision, reliability, and elegance. Its creations embody American heritage fused with Swiss design and technology - a perfect wedding of tradition and innovation. Inspired by the pioneers of the sea, the Hamilton Khaki Navy Belowzero Auto Titanium H78535380 combines precision and style to keep you on time, in and out of the water. The watch makes an immediate sporting statement with its cushion case crafted entirely from titanium, delivering outstanding durability without the weight. Its gray tone is elevated by a bold brushed finish that radiates toughness from every angle. The case measures an imposing 46 mm in diameter and 15.70 mm thick - dimensions that make this model a natural fit for larger wrists. It features 4 protruding lugs, each secured by a single thick octagonal screw, adding a distinctly masculine edge to the design. The striking case is fitted with a unidirectional bezel marked with raised dots at every five minutes and subtle white bars for the first 15 minutes. Its knurled edges give wearers a firm grip for easy rotation. A scratch-resistant sapphire crystal with an anti-reflective coating protects the dial while ensuring maximum legibility. On the right side, a large, knurled, screw-down, and carefully protected crown bears the brand's signature and handles hour and minute adjustment for accurate timekeeping. The watch is also equipped with a helium escape valve on the left side of the case, enhancing durability and allowing it to withstand greater water pressure at greater depths. The caseback is a screw-down titanium construction offering an exceptional water resistance of 100 ATM, and is beautifully decorated with a relief engraving of a deep-sea diver's helmet.

The Dial

The watch features a clean, understated dial in dark gray with a striking sandblasted finish. The layout is refreshingly simple, ensuring effortless readability at a glance. A white minute track runs along the perimeter, with yellow markers at every 5-minute interval. Hour indices are bold Arabic numerals from 0 to 11 in white, creating an elegant contrast. The hands are rendered in yellow with a distinctive shape that adds a refined edge. They are paired with a slim gray seconds hand tipped with a yellow arrowhead. These luminescent yellow accents bring energy to the dial and ensure optimal legibility in all lighting conditions, including low light. The brand signature is printed at 12 o'clock, while the collection name, movement type, and water resistance rating appear at 6 o'clock.

The Movement

This watch is powered by a high-performance Swiss-made automatic movement - specifically the in-house H-10 caliber, based on the ETA C07.111, beating at 21,600 vibrations per hour (3 Hz). It features 25 jewels and an impressive 80-hour power reserve. Reliable and precise, it delivers a clean three-hand analog display.

The Bracelet

The watch's elegance is matched by a comfortable yellow rubber strap. Flexible and modern, it creates a striking contrast with the dial's tones. At 20 mm at the lug width, it fastens securely with an 18 mm pin buckle. The textured surface adds a pleasant feel against the wrist.

Water Resistance

Water-resistant to 100 atmospheres - that's 1,000 meters - this watch is built for serious deep-sea diving. A screw-down caseback and crown ensure a watertight seal, so you can explore the ocean's depths with confidence. A helium escape valve manages helium buildup inside the case during saturation diving, keeping pressure levels in check. Whatever the depth, this watch is ready for it.
