My Seiko uses the 7T34 calibre and was 3 seconds slow in it's first
year some 25 years ago. I don't have an exact current figure but it's
running 8 seconds slow after having a battery replaced about a year
ago. Now you have prompted me I will set it and record the drift
accurately.

What's more it has a slide rule bezel and I'm sure I'm not the only
time-nut who is into slide rules.
