Historical significance
- Science Museum Group describes a Waltham International digital watch with a quartz movement made by Société des Gardes Temps (SGT), Switzerland, in 1972. This specific attribution is not a continuation of an American factory claim inferred from the Waltham name.
- The museum places it among early LCD wristwatches and contrasts lower display power consumption with LED designs. The exact photograph shows its rectangular display and bracelet. The consulted record does not specify its LCD mode, calibre, case alloy, dimensions or serial number.
- Seiko’s history separately describes dynamic-scattering and field-effect LCD technologies. That general history must not be used to assign a particular mode to this Waltham without object-specific evidence.
- Present operation, service history, battery condition and current public display have not been verified. The photograph is an identification view, not a condition report or an accuracy test.
