    Hello all, first post on the forum. I'm a member of watchuseek and I was hoping for some quick advice/answers/info but didn't get any responses, so hopefully I can get some here. Not sure if this belongs here or in vintage, I feel as if these flirt on the line.

    I've been looking for a chronograph for some time, as well as trying to find a reason to enter into the vintage watch market and I think I've found that through the 3510.50 or the 3511.50. Problem is, I don't know a whole lot about either of them, more about the 3510, and very little about the 3511.

    I'm aware that the 3510.50 is a reduced version of the original speedmaster with a smaller size and an automatic movement instead of the manual wind movement. The small size is perfect for my smaller wrists and all I've found is positive things about the movement. It seems that more information is readily available on this one.

    As far as the 3511.50, from what I've read, it was released only to a Japanese market in the early/mid 90s, and has a version of the Valjoux 7750 movement, the 1164. I've read that this can be rather loud, and also when the movement moves, it can be noticeable. But I like that it has the date.


    I guess my question is, for a similar cost, similar year, and similar condition, which offers more bang for your buck? also, any other info is more than welcome!

    Completely different watches, the 3511.50 is an ETA 7750 base, full integrated chronograph, the 3510.50 is still an ETA base but with a DD piggyback chrono module, considered to be weaker and more costly to service. The 3511.50 is my choice between the two, I just trust the movement far more.

    Greatly appreciate your response.

    Right right, I know theyre not the same, just like the look of both of them and they're close in price/condition.

    For whatever reason, the piggy backed movement doesn't really turn me off. I've seen people say how it's not a cost effective movement to service and that a watch repairman may simply replace instead of try and fix. That kind of worries me a little. But I think it gives uniqueness.

    I would take the 35115000. The 7750 is a far superior set-up than the 2892 with the DD module stuck on it. The 7750 based watches are some of the most reliable and accurate movements I service.

    Cheers, Al

    Personally I find the layout of the 3511.50 dial more attractive. The dial of the Speedy Reduced looks kinda squished, but maybe that's just me.

    Al,
    I am new to the forum and have a couple of (3) questions about the 35115000
    1. How do you date / determine year of manufacture of each watch? #53884609 is on the back of the watch I am considering
    2. Are the numbers on the Tach Bezel typically "filled" Black or are they intended to be completely stainless / stamped in appearance?
    3. Was there a reason for them only being introduced exclusively to the Japanese market for only a few years?

    Thanks for your time!

    There are serial number charts you can use to date the watch...someone posted one on the forum recently.

    The bezel numbers are filled with black paint.

    Cheers, Al

    I have the speedmaster triple date with what i think is a valjoux movement for twelve years now and hasnt missed a beat. I dont like the bracelet as the one on the reduced moonwatch but a better watch all round. I had a reduced moonwatch from new but omega swapped it out for the triple date. The reduced model had really bad quality issues on everything apart from the movement.
    For that reason i would buy a second hand professional any day of the week. Put up with the diference in size and enjoy a classic.

    Does the 3511.50 has sapphire crystal? manual winding or automatic movement?

    Thanks for confirmation. Does anyone knows if the silver bezel on the 3511 can be replaced with the black one of the 3510 or the 3520.50 ? I prefer the black bezel look over the silver one, guess could just replace the insert

    I ended up just buying the 3513.53 (Japanese only version) which comes with the black bezel since could not confirm if black and silver inserts were interchangeable.
