help Seiko Prospex SPB283 FAQ
Is the Seiko Prospex SPB283 actually a titanium dive watch?
No, the SPB283 is a stainless-steel Prospex model from the 1968 Mechanical Diver's Modern Re-interpretation line. Listings describing it as titanium should be treated as inaccurate unless they refer to a different Seiko reference.
What movement is used in the SPB283?
The SPB283 uses Seiko's automatic 6R35 movement with a power reserve of approximately 70 hours. It can also be hand-wound and includes a date display.
Can the SPB283 be used for recreational diving?
It has a unidirectional timing bezel, screw-down crown, sapphire crystal, and 200-metre water resistance. Those are functional dive-watch specifications, although seals should be pressure-tested periodically if the watch is regularly submerged.
How large does the SPB283 wear on the wrist?
Its case is approximately 42mm across, placing it in the medium-to-large dive-watch range. The curved lugs help, but buyers with smaller wrists should try it on rather than judging fit from diameter alone.
