Cool watch. I went through the 1962 to 1964 Linebooks and came up empty.
1963 Unknown for me as of now.
Closest I could find is this 1968 Lady of Fashion "AU" advert.

1967 Linebook confirmation. Suggesting it was still this model in 1963.

Same model #71204 as the LoF, but before 1967 this was the Heiress of Time "A"
1964 LB 156

Wow, well found Ken. Pre 1967 appears to be
1963 Heiress of Time "A"
