Paolo,
so, if I understand well, the HLF fit well also in the
1163 cases with serial from 141.000 to 144.500???
Or it is better to use the HLD???
Thanks

: What i know is:

: Autavia 1163 with 141000 to 144500 cases all fit the HLD end
: pieces. Early watches shown on catalogues have the smaller HLD.
: Autavia 1163 with cases serials from 2xxxxx fit the HLF ends (there
: still were few batches of thin cases also after 2xxxxx)
: The 1163V case from 270000 (Schmitz) is very very close to the
: early 143xxx 144xxx style and also should fit the HLD (and often
: we find HLD also on late viceroys, with Gay Freres bracelet or
: cheaper type too)
: The HLF were made to well fit all 1163 cases.

: About date codes this is what i have seen:

: 1-69 : HLD with no fliplock clasp
: 2-69 : HLD with no fliplock clasp
: 3-69 : HLD with no fliplock clasp or fliplock clasp
: 4-69 and later : HLF with fliplock clasp
