March 14, 2020 at 9:43 pm - Reply I have an old Seiko aviator watch with 4 chronographs circa 1995. The E6B computer will not turn or is very hard to turn. I would like to take it apart and see if I can fix it. Seiko repair over in Mahwah said they couldn’t do it.

How can I get it fixed Esslinger Staff December 16, 2020 at 6:06 pm - Reply It sounds like maybe the stem is broken or at least no longer engaging with the mechanism to move the hands.
