Historical significance

  • Cleveland's record identifies an Engraved Egg Watch designed by Denis Martinot, with decoration attributed to Theodor de Bry. The qualification belongs to the decoration; it should not be silently removed.
  • The museum lists silver, steel and rock crystal. The reviewed photograph shows the engraved exterior, not a complete inspection of its movement or a materials analysis.
  • Its shaped case offers a specific late-sixteenth-century example for studying portable timekeepers as both technical objects and decorated metalwork. It is not proof of a general production pattern or an invention date.
  • Record the collection number when comparing this watch with other egg-shaped watches. An exterior resemblance alone cannot establish that a later auction listing describes this exact object.
  • No escapement specification, running condition or current-gallery location is asserted here because those details were not established by the retrieved record.
