Seiko 5 Sports SRPD93
42.5mm dive-style sports watch with 4R36 and day-date · Reviewed by Drew · amazon.com live, Sept 24 2026
Why it scored a 79
The Seiko 5 Sports SRPD93 pairs Seiko's proven 4R36 caliber with a 42.5mm steel case, rotating bezel, day-date and 100m water resistance. Reliability scores 82 and the 3-year warranty scores 78. Satisfaction is 88 because 223 ratings at 4.5 stars trigger our small-sample deduction. Features is the lowest factor at 72: a Hardlex crystal and a push-pull crown, while the Orient Kamasu RA-AA0003R adds sapphire and 200m for $262.22. Value is 78 at $280.00. The listing also mixes variant descriptions, so confirm the dial color before you buy.

Should you buy the Seiko 5 Sports SRPD93?
The Seiko 5 Sports SRPD93 is for someone who wants a Seiko automatic with a sporty bezel and does not need dive-grade specs. At $280.00 (list $350.00) it ranks #7 of 10 in our Automatic Watches category. Check the photos, because the listing text describes a black case on a green nylon strap while the SRPD93 reference is blue on silicone. For sapphire at a lower price, get the Orient Kamasu RA-AA0003R. For a proper Seiko diver, see the Seiko Prospex Turtle SRPE93.
Where it earns its score
- Same engine as the Turtle. The 24-jewel 4R36 is the caliber in the $420.00 Seiko Prospex Turtle SRPE93, for $140 less.
- Day-date and bezel. A unidirectional rotating bezel and day-date window cover everyday timing jobs.
- 100m rating. Ten bar handles swimming, twice the 50m of the Seiko Presage Cocktail Time SRPB41.
- 3-year warranty. Seiko USA covers it for 3 years from an authorized dealer, versus 1 year on the Orient models.
What to know first
- Features is the lowest factor at 72. Hardlex instead of sapphire and a push-pull crown fall short of the Orient Kamasu RA-AA0003R.
- Variant confusion. The bullets describe a black-coated case with a green nylon strap, but Seiko lists SRPD93 as a blue dial on black silicone.
- Smaller rating base. 223 ratings is enough to trust the 4.5 stars, but our rubric trims Satisfaction to 88 below 300 ratings.
Our verdict
The Seiko 5 Sports SRPD93 scores 79, a Fair Buy and #7 in our Automatic Watches category. Satisfaction (88), Reliability (82) and Warranty (78) lead, while Features (72) holds it back. Buy it if you want a Seiko 4R36 sports watch at $280.00 and like the blue dial. For sapphire and 200m for less money, the Orient Kamasu RA-AA0003R (83) is the better buy.
