# Professional Dive Watches The Seiko Prospex Marinemaster SLA079J Revives the 1968 Marinemaster By Amy Duong | Published 2026-07-02 | Fashion Source: Trend Hunter, https://www.trendhunter.com/trends/prospex-marinemaster-sla079j References: [seikoboutique](http://seikoboutique.co.uk/)  The [Seiko](https://www.trendhunter.com/trends/prospex-marinemaster-1968) Prospex Marinemaster SLA079J revives one of the brand's most recognizable [professional dive watches](https://www.trendhunter.com/trends/pam01756), drawing directly from the [1968 6159-7001](https://www.trendhunter.com/trends/prospex-marinemaster-1968-1) and later SBDX001. The new release updates the historic Marinemaster with a monochromatic black finish, combining a textured dial, matching hard-coated rotating bezel, and angular stainless steel case that preserve the silhouette of its predecessors while introducing a more contemporary aesthetic. LumiBrite-filled hands and indices, a discreet date display, and a dual-curved sapphire crystal prioritize underwater legibility without disrupting the watch's clean, high-contrast design. On the inside, Seiko equips the watch with its automatic Caliber 8L35 movement, delivering high-beat performance, manual winding capability, and a 50-hour power reserve. A screw-down crown and case back provide 300 meters of water resistance, reinforcing its professional diving credentials.
