| Notes: | Twin quartz crystals for greater accuracy. Note that the original 1980s catalogues state ±20 seconds/year, however Seiko later produced a "Value Checking List" with battery cross-reference chart. The latest public edition of this (available here: https://service.seiko.com.au/i/seiko/documents/batteries/Seiko%20Battery%20Guide.pdf ) states an accuracy of just ±10 seconds/year. I believe they revised it based on past data, so I'm using this as the official accuracy figure. |
