The Tissot 27-21T watch movement is a manual wind calibre that was in use around 1943. It is considered equivalent to other similar movements such as the Aurore-Villeret 120, Bulova 6AH, FHF 120, and their variants. Specific design details differentiate the Bulova calibres from the FHF calibres, suggesting that the ebauches for the Tissot 27-21T may have originated from Aurore-Villeret. The differences between the various calibres listed, including 120 through 122, 122N, 124, 125, 127, 1220, and 1221, are not known.
