Seiko7A38-xxxx Variations: Updated Jan 2021

The bulk of the data on this spreadsheet was originally copied from Seiko’s Oceania (Australia) database, as far back as 2009. (Unfortunately they discontinued public read only access in 2020). I’d noticed at the time that a few known 7A38 models / product codes were missing and there were other obvious errors, so over the years I’ve made a number of revisions to it. See comments at the foot of the spreadsheet.
