First Seiko Automatic Advice

Hi.

I am looking to get something to replace my Citizen NY2300. I love this watch, and it has kept the time very well but it is just too small now. Even on a different strap it just doesn't feel right for me. Unfortunately, Citizen don't make a NY2300 that is slightly bigger!

I have found two Seiko's I like but I am not sure what are the differences. One as the 7S26 movement and the other has the 7S36. What does this mean?

Thank you!

The 7s26 has 21 jewels while the 7s36 has 23 jewels. The extra 2 jewels in the 7s36 don't really add anything performance wise. Both are considered tough or robust, that's why Seiko puts them into the '5' series of watches.

Thank you for your reply.

That's what I was wondering why the difference of two jewels! Would you say the 7s26 is an accurate and reliable movement?

Thanks!

The 7s26 is a very reliable movement. That's why it's in all of the skx___ iso diver models.

As for accuracy, it can be hit or miss. There are some folks on here who have monsters that run about 30 seconds fast a day. I personally have a SNKA05 with the 7s26 that is -1.5s/day right out of the box. It's been like that for over 3 months now. The good news is that these movements are easy to regulate if you decide that the accuracy should be held to a tighter tolerance than what you are getting.
