The Seiko Prospex SLA051J, known among collectors as the “Willard,” is a modern reimagining of one of the most iconic divers in the brand’s history. Inspired by the legendary 6105 worn in the 1970s and immortalized on Martin Sheen’s wrist in the film Apocalypse Now, this model carries that heritage with a much more refined and contemporary build.

The 44mm steel case retains the classic asymmetrical design that made the Willard so recognizable, offering excellent ergonomics and a strong presence on the wrist. This piece is in excellent condition, preserving its original structure very well, although it shows visible scratches on the side of the case and also on the bezel — marks consistent with use that do not compromise its beauty.

The black dial with highly legible Lumibrite markers, combined with the unidirectional rotating bezel and the crown protected at 4 o’clock, reinforces its identity as a true tool watch. It offers 200 meters of water resistance, an anti-reflective sapphire crystal, and all the solidity expected from a high-end Prospex.

At its heart is the 8L35 automatic caliber, a movement derived from the same base used in mechanical Grand Seikos, renowned for its robustness, accuracy, and excellent construction. A watch that combines history, presence, and real diving performance — ideal for those seeking a serious diver with plenty of personality and pedigree within Seiko.
