“The Seiko SKX013 is a smaller and in my opinion, much dressier version of the SKX007. The build quality is amazing, except for the sharp top rim edge of the bezel, which creates the circular channel for the bezel insert.
The jubilee bracelet is the way to go, and the endlinks can be slightly bent before reinstalling to better hug the case and greatly reduce the jiggly sounds from the bracelet.
With a bit of trial and error, I was able to regulate the 7S26 movement to +/- 2 seconds a day when worn regularly. That's amazing accuracy for such a no-nonsense movement. It can also be back-hacked: temporarily stop the seconds by moving the crown backwards, give it a tap and a slight forward crown turn to restart.
The purchase through Longislandwatch.com was simple, with quick delivery.”
