what about the 1152 ?? nt
In Response To: more 1154/1164 info from ch ()

: I forgot to post this second message I received
: from Omega.ch earlier this month about the
: differences between the two calibres 1154
: and 1164. This message contains info a
: little different from that I posted earlier,
: hope it is informative to all interested
: parties.

: Mus.

: Dear Sir,
: >
: Further to your above enquiry, we have
: following details available to explain the
: difference between the indicated movements
: of caliber 1154 v. 1164 : ( automatic
: chronographs )

: in order to improve the quality of our
: movements, it has been decided to switch
: from the past partly goldplated movement
: parts or having a simple rhodium plating, to
: an improved version in quality and entirely
: rhodium-plated

: * these changes have started to be effective in
: 1995 ;
: Therefore, the former calibre 1154 was
: originally having 17 jewels and gilt-plated
: movement parts. This caliber is the
: "chronometer " version of the
: basic movement of calibre 1155 ( base
: :Valjoux 7750 ). However, some newer
: movements of calibre 1154 have been partly
: delivered with 25 jewels and simple
: rhodium-plating.

: * in 1995, the calibre 1154 has been replaced
: gradually, by the new version of calibre
: 1164, which is an improved version,
: completely
: rhodium-plated, and having of course, 25 jewels

: * it goes without say, that all spare parts of
: cal. 1154 cannot be used on the movements of
: cal. 1164 ...

: We hope sincerely that you have now a clearer
: view of the situation between cal. 1154 and
: the present cal. 1164.
