SBDX001 — I’ve Owned It 10+ Years; These Three Flaws Still Bug Me
I’ve owned my Seiko Marinemaster SBDX001 for over ten years and it still impresses — but the original used a Hardlex crystal, a steel bezel insert, and a clasp/diving extension that felt flimsy. Fratello’s recent video argues the best Seiko diver has improved; here’s what actually mattered to me.

SBDX001: a long-term owner’s paradox
I bought a Seiko Marinemaster SBDX001 more than a decade ago. It still performs and wears like a serious tool watch. That said, three specific details never stopped nagging me.
What I call the three flaws
- Hardlex crystal instead of sapphire.
- Steel bezel insert rather than a harder material.
- Clasp and diving extension that feel lightweight and a bit flimsy on the wrist.
Those are practical complaints, not aesthetics. The crystal and bezel determine scratch resistance and legibility. The clasp governs on-wrist security and confidence during long dives or daily wear.
Context: Seiko didn’t stand still
Seiko produced a number of references after the SBDX001. As Fratello Watches – The Magazine Dedicated To Luxury Watches first reported in its accompanying video, the conversation now is whether the modern iterations have addressed these precise pain points. The piece frames the newer diver as an improvement over the old Marinemaster for exactly these reasons.
Why those three changes matter
Sapphire would reduce long-term scuffs and maintain clarity. A harder bezel insert changes the watch’s perceived and actual durability—important for a dive watch intended to see rough use. A beefier, more secure clasp and extension alter how the watch behaves during activity; a flimsy-feeling system undermines confidence regardless of the movement inside.
Buying angle and short forecast
If you’re deciding between an original SBDX001 and later Marinemaster references, focus on those three items: crystal material, bezel insert material, and clasp construction. Watch Fratello’s video to see the comparisons they highlight, then inspect those elements in person. If later references have indeed upgraded those parts, expect the originals to remain desirable for collectors but to trade on nostalgia rather than functional advantage.
Final provocation: if you value heirloom durability over collector purity, prioritize hardware upgrades (sapphire, harder bezel insert, solid clasp) when you negotiate a purchase.
