  1. A 7750 has the following measurements for the pinions:

    Hour 2.00mm

    Minute 1.20mm

    So, the center hole of the dial needs to be a slight bit larger than 2mm.

    If you are able to broach the center hole, it may work.

    The center hole looks to be bang on 2mm... A touch of a file should take care of that :) I'm still having trouble accessing Cousins, but would I be right in thinking they'd sell the correct handsets for the movements as well?

  2. Dial looks like it's for a Seagull. I think I gave one to Toad that was just like it.

    Dunno that an A7750 mod-tricompax would fit it properly... The 7750 has large hour/minute pinions- That dial that you have has a small opening at the center and I don't think it will fit over the pinions regardless whether the subdials lined up with the pinions or not.

    The center hole shouldn't be a problem, I've enlarged the center holes on Sub dials to cram the dial over GMT movements before ;) (although I didn't broach the subdials) Thanks for the feedback though :)

  3. I can shot some pics of the 2 dials I have when I get home tonight. One is sec. @6 the other sec @9. will get you measurements as well.

    To Toads comment, there is a seller on eBay that comes from time to time that has the sec @6 movements.

    From your pic, it looks like a tricompax movement would work.

    That'd be awesome, as I can then compare dimensions with mine :) I know the dial's less than pristine, but it's really taken my fancy (especially after I lumed the markers :lol: ) so I'd really like to try and use it in the project :) Since the above pic was taken, I re-enameled the bezel scale, and overall, I think it's looking pretty sharp on its new strap :)

  4. A standard Valjoux/ETA and Asian 7750 has:

    -Minute counter at 12:00

    -Running seconds at 9:00

    -Hour counter at 6:00

    A tricompax Valjoux/ETA 7753 has:

    -Running seconds at 9:00

    -Hour counter at 6:00

    -Minute counter at 3:00

    Most reps with the tricompax layout 775x watches are in fact modified 7750's with the minute counter output shifted to 3:00. Because the minute counter is not a constantly running gear like running seconds, the shift in output for this function is less critical. And some reps do in fact have true 7753's inside (they are quite pricey, however).

    Modified A7750 movements that shift running seconds output to 6:00, 12:00 or 3:00 may exhibit some problems over time; how soon or long that takes is really luck of the draw.

    For more information regarding these movements, have a look at some of the articles Zigmeister has done on the 7750's. Lots of good reading and disection which outlines where these movements go wrong.

    Thanks for the information, that's reassuring to know, as Project Daytona has the seconds @ 9 subdial, and I figured if I was going to build a wearable Daytona using that dial, I might as well have one with working chrono features, rather than day/date/24 hour, simply because it had the correct detailing on the sub-dials (I'd be quite happy with the d/d/24 movement, providing the subdials reflected those measurements :) )

  5. yeah i remember that too.. wasn't it an episode of CSI or something?

    If I remember, it was something more like Judge Judy, and I think the guy tried to use a rep to pay a debt, but I'm a bit fuzzy on the details. The thing I thought was nice, was although the expert explained that it was a rep, he didn't just say "This is worthless..." he did acknowledge that it did have some (although not much :lol: ) financial value :)

  6. Today's my first wedding anniversary, muchachos :tu::drinks:

    In honor of this, I'm wearing the watch my bro Sixx generously gave me as wedding present :)

    As the first year is traditionally a paper gift, this is what I made for Emily...

    In town, I treated Project Daytona to some new shoes, all it needs now, is a Rolex buckle :yeah:

    Have a great day, my brothers :drinks:
