Import Tips

Classify as parts not complete movements; provide diagrams showing missing escapement per note 1(e)

Ensure documentation specifies watch caliber compatibility (e.g

ETA 2824, Sellita SW200)

Avoid bulk packaging that suggests general industrial use; retail watch part presentation preferred
