Our take on the Seiko 5 Sports SRPD51 Automatic Blue Dial Watch

The Seiko 5 Sports SRPD51 is a 42.5mm stainless steel automatic dive-style watch with a blue sunburst dial, powered by the 4R36 movement with hacking, hand-winding and about 41 hours of reserve. It is the modern Seiko 5 Sports line that replaced the SKX007, keeping the dive look but adding an exhibition caseback and a 4 o'clock crown. Buyers get a robust everyday watch with 100m water resistance and a day-date at a modest outlay, though the Hardlex crystal, pressed caseback and lack of a screw-down crown are the usual trade-offs against pricier divers. It suits people who want a mechanical beater with real heritage rather than a quartz fashion watch.

Pros
  • 4R36 automatic movement with hacking and hand-winding
  • Day-date complication and 41-hour power reserve
  • Solid stainless steel case with 100m water resistance
  • Classic blue sunburst dial with good legibility
  • Exhibition caseback shows the movement
  • Wide 22mm lug spacing makes strap swaps easy
Cons
  • Hardlex crystal scratches more easily than sapphire
  • 13.4mm thick and 170g, so it sits heavy on smaller wrists
  • No screw-down crown; 100m rating is modest for a dive-style watch
  • Stock bracelet is functional but not a highlight
  • Accuracy is typical entry-level automatic, not chronometer-grade

Questions and answers

Is the SRPD51 a good first automatic watch?
Yes. The 4R36 movement is proven, the watch is tough enough for daily wear, and it has the features beginners want: hacking, hand-winding and a day-date. It is a common entry point into mechanical watches.
How does it compare with the SKX007?
It uses the same dive-style case shape but adds the 4R36 movement with hacking and hand-winding, an exhibition caseback and a 4 o'clock crown. It drops the screw-down crown and ISO dive rating, so it is a lifestyle watch rather than a certified diver.
Does it have a sapphire crystal?
No. It uses Seiko's Hardlex mineral crystal, which is more scratch-resistant than plain mineral glass but less so than sapphire. Many owners accept this at the price.
What is the water resistance?
It is rated to 10 bar, or 100 meters. That covers swimming and showering, but the crown does not screw down, so it is not intended for diving.
Can I change the strap?
Yes. It takes 22mm straps, and the drilled lugs make swapping easy. Many owners replace the stock bracelet with a NATO or leather strap.
How accurate is the 4R36 movement?
Seiko rates it within roughly -35 to +45 seconds per day. Real-world examples often do better, but expect a minute or so of variation daily.
Where is the Seiko 5 Sports SRPD51 Automatic Blue Dial Watch cheapest?
At KICKS CREW, for $366.21, as of our latest check.
What do buyers say about the Seiko 5 Sports SRPD51 Automatic Blue Dial Watch?
Rated 4 out of 5 from 12 ratings.
