Thank you for pursuing this with TAG Heuer and thank you for sharing your findings here. It would be interesting to try to sort these "batches" and see which version of the printing goes with which serial numbers. But this may not be realistic.

Sorry that others did not reply, but the Solunar remains a bit of a niche watch, without a big following. So it may have been a conversation with yourself, but I know that others will benefit from your postings.

Thanks again,

Jeff

: were more loose, so different batches might have different
: printings..." So much for precision time keeping! I was
: correct in my assumption that the Swiss are not into oceans...

: Great conversation with myself!
