Perfect “Period-Correct” Restoration: Collectors who own highly valuable, mid-century watches—like a 1950s or 1960s Cartier Tank Louis or Cintrée—will pay a steep premium for an EJ clasp. It allows them to complete a “period-correct” setup, exponentially increasing the total value of their vintage watch.
