Authentication Notes
Bezel
Medium
Dot-over-90 (DON) bezels
Early 145.022 bezels place the dot over the '90' on the tachymeter scale; DON bezels are period-correct for early examples and frequently swapped in.
Caseback
Medium
Seahorse and lunar engraving
Casebacks carry the seahorse hippocampus and 'The First Watch Worn on the Moon / Flight-Qualified by NASA' text; wording evolved over the run and should match the period.
