Built to last
You may be wondering what the “5” refers to in the name of the Seiko 5 Sports SRPD91. Seiko’s 5 Sports range dates back to the 1960s and is the manufacturer’s promise of the following five attributes:
(1) an automatic movement
(2) a day-date display at the 3 o’clock position
(3) practical water resistance
(4) a recessed crown at the 4 o’clock position that protects it from knocks
(5) a case and bracelet or strap built for durability—and the supplied nylon NATO strap was made to last.
DIVEIN has thoroughly tested the SPRD91 on land and sea. I have worn it both at the office and the gym. I’ve also taken it swimming in the pool and the ocean, and it has held up splendidly.
It’s a do-it-all watch that could quite as easily be worn with a shirt and blazer as with shorts and a T-shirt. I also love that it has a screw-down exhibition caseback, where you can see the mainspring of the movement oscillate like a beating heart.
Price/Quality Ratio
For under $300 USD you are getting a very handsome watch with the excellent build quality you’d expect of a reputable Japanese watchmaker like Seiko. The action on the bezel is extremely smooth yet sturdy. It’s great for timing a run or a swim. For a dive, stick to your dive computer and maybe wear a Casio G-Shock as a back up.
With the Seiko 5 Sports SRPD91, I put my money where my mouth is and bought it for myself back in 2020. It’s one of the few watches I own that gets consistent wrist time because it represents a happy medium between functionality and style. I can throw it on and face the day no matter what it brings.

Final impressions
If I had to complain about something, it would be height. Ideally, the SRPD’s case would be a little bit thinner: on a double-pass NATO strap I do find that it sits high on my wrist. Also, it’s not as accurate as the high-end (and much more expensive) automatic dive watches.
My SRPD tends to lose around 15 seconds per day, which is well within the tolerances covered by the guarantee.
Nevertheless, all in all, this watch continues to bring me plenty of joy after over three years of use and we at DIVEIN wholeheartedly recommend it.
