Job Complete – SEIKO 6619-8050 “Sportmatic”

By October 20, 2017 Uncategorized

This watch was a bit of a pain to sort out. The calendar system on the 6619 movement is a little weak, so I ended up replacing and adjusting a few components there to get the date change working correctly. Besides that, the watch got a new crystal, movement service and a new set of seals. The 6619 movement tends to be quite noisy when winding.
