Review: Super classy Seiko - One of the finest Seiko watches. Very classy
Review: Average - The green is not rich and tends more towards a dull black. The numerical and hour marks are not pronounced enough for clarity. Sapphire glass is not clear enough either. Average for me, though there is a cult following for this watch.

## Questions & Answers

**Q: What makes this model limited compare to model spb121j1?**
A: This is not a limited edition.  SPB121JI is an international market release by Seiko, and replaced the popular SARB017. This model  SADC091 is the same model produced for the Japanese market. Maybe that's why they called it a Limited Edition, the model number is exclusive to Japan, not the watch.

**Q: The description says it’s a quartz watch the dial say automatic, love the green dial but I am confused 😐**
A: Hello,

This model is 100% automatic, mechanical movement.

Best regards,

GTJ

**Q: I have small wrists 6 1/4 inch would this  adjust enough to fit me?**
A: Hello,

The OEM strap will not fit your wrist. You'll have to find a shorter strap to use if you like this watch.

Best regards,
GTJ

**Q: Does it have sapphire crystal?**
A: Has a sapphire Chrystal, 6R35 movement and screw down crown
