In Response To: And........if so............ ()

while there may have been some overlap in the production, the 17 jewel movement was used in the earlier divers watches and the 25 jewel movement was used in the later ones.

so it's not like Mr. Shelby, offering the Cobra with a choice of the 289 or 427 engine, but a matter of when the watch was produced.



: ....(if they did have two movements for the
: same watch)...was this due to a company-wide
: "model change" or were these
: "interchangable", etc.?

: I'm wondering for the same reason the 1966
: Chris Craft Commander came with a MEL 430,
: Ford 427, Chrysler 426B (it was due to
: necessity that year due to labor strikes in
: Detroit, etc., etc.). Sometimes they would
: even sneak a 427 sideoiler into the marine
: shop and sell it as a "regular"
: marine motor, odd, expensive, same power
: level, same compression, but very expensive
: oil routing internally for "race
: only", and just one of those strange
: things that happen during production and
: meeting delivery dates.

: Since to date, there have been no other 25
: jewel Spiros spotted, I'm still curious if
: this one came off the "assembly
: line" or if it has a movement from
: another Heuer, ETA or not.

: regards, and thanks for the responses,
