Seiko is resurrecting the iconic Marinemaster name with a fresh perspective for 2023. This new trio of watches seamlessly blends elements from the original Marinemaster and Seiko’s legendary 62MAS diver, offering enthusiasts a dive watch that marries the best of the past and the present.

Embracing the Legacy: The 2023 Marinemaster Trio

Seiko originally introduced the Marinemaster to the world in 2000, positioning it as a robust, fully-equipped diver’s watch. With a formidable 44mm monobloc case, 300 meters of water resistance, and helium-proof construction (sans valve), the Marinemaster quickly became a favorite among enthusiasts. The last iteration, the SBDX017, bowed out in 2018, leaving a void that Seiko has now decided to fill.

For 2023, Seiko has reimagined the Marinemaster to broaden its appeal. The iconic one-piece case is replaced by a more modest 39.5mm size, measuring just 12.3mm in thickness. This redesign draws inspiration from the 62MAS and its reissues but maintains a distinct identity with brushed surfaces and prominent polished bevels. Notably, the Marinemaster now boasts an exhibition caseback, a first for Seiko divers.

The new Marinemaster offers a trio of dial options to suit diverse tastes. The blue (SJE099) and black (SJE101) dials secure a permanent spot in Seiko’s Prospex line, while the silver (SJE097) dial, limited to 1,000 pieces, commemorates Seiko’s 100th anniversary. Each dial features horizontal grooves, with the “Marinemaster” insignia proudly displayed at 12 o’clock and the Prospex “X” at 6 o’clock. A circular date window sits at 4:30, adding a functional touch.

At the heart of the Marinemaster lineup beats the Seiko caliber 6L37. This automatic movement, with a robust 45-hour power reserve and a 4 Hz beat rate, made its debut in the Prospex SJE093 Limited Edition earlier this year.

Complementing the Marinemaster’s refreshed design is a brand-new bracelet. Featuring three rounded links, with the middle links sporting a combination of mirror-polished and brushed surfaces, this bracelet exudes both elegance and durability. A push-button clasp and diver’s extension add practicality to the mix, although the absence of a tool-free micro-adjust might raise eyebrows in a segment where competitors often offer quick-adjust mechanisms. With a slated release in December, the Marinemaster comes with a price tag of $2,800 USD.
