Our take on the SEIKO 5 Sports series SBSA291/SRPL55J1/SRPL55 Automatic Mechanical Men's Wrist watch

The Seiko 5 Sports SRPL55 is a mechanical automatic dive-style watch with the 4R36 movement, which winds itself as you wear it and can also be wound by hand. It has hacking seconds, a day-date calendar and about 41 hours of power reserve when fully wound. Accuracy is rated at +45 to -35 seconds a day, which is normal for this movement class and looser than the sub-10-second specs of pricier Swiss automatics. It suits buyers who want a real mechanical movement, a day-date and a rugged everyday look without paying luxury prices. Against rivals like the Orient Kamasu or the Citizen Promaster, it trades some accuracy and water-resistance specs for Seiko's broad parts support and the 5 Sports line's huge variety of dials and cases.

Questions and answers

Is the Seiko 5 Sports SRPL55 a true automatic?
Yes. It runs on the 4R36 mechanical self-winding movement and also accepts manual winding through the crown.
How accurate is it?
Seiko rates it at +45 to -35 seconds a day. Real-world examples often do better, but expect some drift compared with quartz.
Does it have a day-date?
Yes. The calendar shows both the day of the week and the date, and the seconds hand hacks for precise setting.
How long does it run off the wrist?
About 41 hours when fully wound, so it keeps going overnight and through a day off.
Is it a real dive watch?
It has dive-style looks but is not rated as a professional diver. Check the case back for its stated water resistance before swimming.
What is in the box?
The watch on its stainless steel bracelet, with Seiko's standard documentation. Confirm the included items with the seller.
