Seiko’s 1968-inspired diver gained a second time zone in 2023 without losing the broad shoulders and four-o’clock crown that make this family so recognizable. The GMT hand adds a useful point of contrast, while the rotating bezel remains dedicated to elapsed time: this is still a dive watch first.
The original pairing makes a good starting point: SPB381 has a green dial and bezel, while SPB383 keeps both black. For something more distinctive, SPB385 pairs an ice-blue, textured dial with a dark bezel—a noticeably different character within the same case.
The important distinction is inside. The 6R54 lets you adjust the 24-hour hand independently, not the local hour hand. That suits tracking another time zone from home; frequent travelers should understand the difference before choosing it over a GMT with a jumping local hour.
What owners love
- The short, downturned lugs make it wear more compactly than the 42mm diameter suggests. It still feels substantial, but the case sits neatly rather than sprawling across the wrist.
- The broad hands and strong lume keep the main time easy to read, even with the extra GMT hand and 24-hour scale. Owners appreciate that the GMT addition hasn't made the dial feel crowded.
Common Criticisms
- The 6R54 has an independently adjustable GMT hand, not an independently adjustable local-hour hand. That's convenient for tracking another time zone from home, but owners who travel wish they could jump the main hour hand without stopping the watch and resetting the local time.
