Authentication Notes
Bracelet
Medium
Hollow vs solid end links
Earlier 16570 bracelets have hollow 501B end links; solid end links appear on later examples. End-link type should match the production period.
Dial
Medium
Black vs Polar white dial
Both black and white ('Polar') dials are factory-correct across the run; the luminous compound (tritium vs LumiNova) must match the production period.
Movement
HighHigh confidence
3185 or 3186 depending on year
Early-to-mid 16570 uses the 3185; later examples use the 3186. The successor 216570 uses the 3187 — a 3187 in a 16570 case is wrong.
