Hello Chuck. I appreciate the information. The date window is at 3 o'clock position. The 12 hour register is at 6 o'clock position. The 30 minute register is at 9 o'clock and the continuous seconds are at the 12 o'clock position. Same position as the automatic pilots watch, so it most likely has the LWO 283 as you suggest. It does have the Royal Oak appearance. I will email Jeff a picture of it for him to post with this message. Once again thank you, Charles.

: Heuer Model 3000 Auto Chronograph
: Posted By: Charles Rush Date: 10/10/05
: 05:09 GMT I have a Heuer Model 3000
: Automatic Chronograph with case reference
: 136.006. Can anyone tell me which movement
: is in this model? It is mint condition with
: the black dial / gold registers and black
: case & bracelet and gold bezel. Any
: information on the movement would be
: appreciated. Thanks, The Buccaneer. Hi
: Charles, I believe this should be a fairly
: straight forward question to answer...
: While having your "3k" in your
: hand, take a gander at the two following
: pictures:
: Pasadena (750.501) Valjoux 7750 based.
: Pilot's (130.006) LWO 283 based.
: If the "3k" has the
: Chronoseconds sub-dial at 12 it's likely a
: Valjoux 7750 based movement, if it has small
: continuious seconds sub-dial at 12 it's
: likely a flavor of LWO 283 movement under
: the dial. Without a picture to go by, I'm
: only guessing, but I'd suspect that since
: the case reference number of your
: "3k" is 13 6 .006 , and the
: Pilot's Automatic model is 13 0 . 006
: that the movement is a LWO 283. But that's
: just my best guess.
: I've written a bit about the Pilot's
: model , and mention the LWO 283 within
: that article in passing. I'll note that this
: movement I've seen 31, 39 and 40 jewel
: versions (hence why I'm using "a flavor
: of the LWO 283 movement" phrase in my
: response). To my knowledge the only way to
: determine which flavor/version is in a watch
: is via direct visual inspection. I hope
: this is helpful. If I remember the
: "3k"'s correctly they have a bit
: of a "Royal Oak" appearance about
: them and are interesting watches. Best of
: fortune with that watch. --
