Our take on the Seiko Prospex SRPL81 Men's Automatic Dive Watch — 45mm Blue Dial

The Seiko Prospex SRPL81 is a 45mm automatic dive watch with a blue dial, powered by the 4R36 movement with day and date. It carries 200m water resistance and a sapphire crystal, which is a step up from the Hardlex usually found on Seiko's entry-level divers. The silicone strap and large case give it a bold wrist presence. It suits divers and desk divers who want real ISO-style dive specs without paying luxury prices, though the 45mm case is big for smaller wrists.

Questions and answers

Is the SRPL81 good for actual diving?
Yes. It is rated to 200m water resistance, which covers recreational diving and swimming. The screw-down crown and caseback are part of that rating.
How does it compare with a Seiko 5 Sports diver?
The Prospex line sits above Seiko 5 Sports. This watch adds sapphire crystal and a higher dive rating, while Seiko 5 models typically use Hardlex and a lower water resistance.
What movement does it use?
The 4R36 automatic caliber. It winds from wrist motion, can be hand-wound, and shows both day and date.
Will the 45mm case fit a small wrist?
It will wear large. At 45mm with a thick case, it suits wrists roughly 7 inches and up better than smaller wrists.
Does it come with a bracelet?
No. It comes on a blue silicone strap. Aftermarket bracelets and straps can be fitted if you want a different look.
Is the crystal scratch resistant?
Yes. It uses sapphire crystal, which is harder and more scratch resistant than the Hardlex on many Seiko divers.
