Seiko Prospex Automatic Men's Watch SPB079J1 Blue Silicone Strap

A black Prospex diver for deep waters: SPB079J1, 42 mm, 200 m

Collection

The Seiko SPB079J1 is part of the Prospex line, the brand's high-end sports range. The Prospex collection has covered diving, altitude, and exploration since the 1960s; this 42 mm black model with 200 m water resistance is a modern and accessible representative.

Case

Made of stainless steel, the case of the Seiko SPB079J1 measures 42 mm in diameter and 13.8 mm in thickness. The unidirectional rotating bezel allows for precise measurement of dive times. The dial is protected by a sapphire crystal, the most scratch-resistant, with anti-reflective treatment. The case back is solid screwed. The water resistance is 200 m, compliant with ISO 6425 diving standards. The indexes and hands are coated with LumiBrite, Seiko's luminous material for extended nighttime legibility.

Movement

The Seiko SPB079J1 is powered by the automatic caliber 6R15, offering a power reserve of approximately 50 hours. The 6R caliber is the high-end of Seiko's production automatic movements: it features hacking and manual winding, and offers a significantly higher power reserve than 4R calibers.

Strap

The silicone strap of the Seiko SPB079J1, closed by a pin buckle, complements the case with consistency. The lug width is 20 mm.
