## Description

Seiko, the home of the oldest and prestigious Japanese watches, is now focused on innovation and sophistication. The Seiko watch is designed as a small jewel personal and intimate. The watches are those harmonious with the environment and the wearer, and their functions offer a reassuring and exciting feeling.

Review: Nice watch. Great sizes for casual wear. Robust movement, but not the best water-resistance (100 ft) - It's a good watch. They discontinued that Seiko movement. It's the 7s26 movement. It will not hack or hand wind, but it's a good movement. I love the size of the dial, and in the Seiko 5 older snk/skx watches they have great selections. Good gift for fathers and regular watch wearing people. The timing can be regulated by yourself if you know what you are doing. I got this one to +5 seconds per day.
Review: An attractive and accurate autoamtic watch - I've wanted a reasonably priced automatic watch for a while. Most are very expensive, this is very reasonably priced. I have had it for a week and it seems to keep time very well. The underside is glass so you can see the mechanism at work which is nice. Altogether I'm very pleased with my purchase.

## Questions & Answers

**Q: Do you have to keep setting the day of the month?**
A: Only when changes in the number of days in the month occur. My beef with the watch is because I'm sedentary a lot of the time being disabled, it never gets sufficient automatic winding so I have to wind it like an ordinary watch which is not easy.

**Q: can you fit a leather watch strap?**
A: No you can’t.

**Q: Is the face scratch  resistant?  How accurate is it?**
A: Hello,
The glass is made of Hardlex which is a mineral with scratch resistant properties. 
On average this watch +/- 40 seconds a day.

**Q: Is the steel 316l?**
A: Yes it is but 316 is still only a basic stainless steel. It's used becouse of its properties that allow a certain ammount of corrosion inhibitors while still allowing decent finishing of surfaces. It can still corrode if not cared for with basic maintenance, Rinse off salt deposits etc. Hope this helps.
