- Does it need a battery?
- No. It runs on Seiko's automatic movement, wound by the motion of your wrist. Wear it regularly and it keeps going; leave it off for a day or two and it stops.
- Can you wind it by hand or set the seconds?
- The 7S26 movement has no hand-winding and no hacking. You set the time and date with the crown, then wear it to build power.
- How accurate is it?
- Seiko rates this class of movement within roughly -20 to +40 seconds a day. Real-world owners often see better, but expect it to drift more than a quartz watch.
- Is it safe for swimming?
- Treat it as a daily-wear watch, not a dive watch. Its water resistance suits hand washing and rain, not swimming or showering.
- What is in the box?
- The watch on its stainless steel bracelet, with tags and paperwork. It arrives new in box.
- How does it compare with the Seiko 5 Sports SRPD models?
- The SNK623K1 is smaller and dressier, with a simpler dial and the older 7S26 movement. The SRPD line is larger, sportier and uses the 4R36, which adds hand-winding and hacking.
