How do these and the Spirotechnique watches relate to watches with a 'Squale Master 100atmos' case? The design of the case is exactly the same and the bezel inlay has the same markers and font (but no inlay at 12 o'clock). Is it possible that the Heuer 1000m and Spirotechnique cases were made by Squale and had a specific case back?

: Sorry for the double post, but it's a heavy
: case watch very similar in appearance to the
: Spirotechnique 200m automatic. I bought one
: new in 1986 for around $300 I think, and at
: the time it was my understanding the
: Spirotechnique "look alike" with
: the automatic ETA 17 oir 25 jewel movement
: (they offered both, depending on the year)
: cost about $1000 more than the quartz
: version.

: The image with the blue band is the 1000m. The
: black band is the Spiro, you can see the
: obvious similarities. Both are GREAT
: watches, I wore my quartz from 1986 to 2004
: when a pin failed and I lost the watch and
: didn't know it fell off due to the physical
: activity at the time, sadly. I looked and
: looked for it, but never found it, so I
: embarked on a worldwide search for a
: replacement, and became aware of the
: Spirotechnique line, etc.

:
: Here is one of mine, with a replacement non
: sapphire crystal, which I will have
: replaced. It gives a good view of the dial
: face.

:
: Here is a side view, comparing the 1000m with
: the Spirotechnique automatic watch. Quartz
: is blue band, Spiro has the black band.

: deployment band.

: Hope this helps clear up what the 1000m is.
: It's a big heavy case with their classic
: dial face, and the cool 4-oclock protected
: crown, but with a lower cost quartz
: movement. All said and done, I'd still be
: wearing mine with great pride if I had not
: lost it.
