    As I recall, no. The clasp itself is 18mm inside.

    However, a more modern bracelet might fit?

    Ok this confuses me because the 1471/815 bracelet is 18mm non-tapered. Thoughts?

    Also, great suggestion on an alternate bracelet. The Seamaster bracelet 1612/932 is known to fit the Speedy Reduced 3539.50 and that bracelet is good with the 4666 clasp.

    Ah, I had assumed the older ones were 18/16. Glad you found an alternate you like.

    I’ve added the micro clasp to my Speedy Pro and 300mc. They make a lot of difference, I highly recommend them.

    I don't think the overhang of the clasp would work for me - don't have am issue yet with lack of microadjustments. Good info all, thanks...

    That's exactly the information that I'd like to know, too: if I should purchase an X-33 Skywalker, what exactly I would need to have a micro-adjusting clasp; from 2019 I'm a proud owner of a Seamaster 300m and I use the micro-adjusting clasp at least twice every day, so I already know that I can't live without it.
    Did you find the solution to your own question?
    Thanks.

    I researched years ago putting an adjustable clasp on old ref. 2298.80 Seamaster Chronograph Titanium with a titanium ref. 1504/826Ti bracelet. It was not fruitful.

    I determined the following was required:

    P/N 117TIZ004664 - titanium version of 6-position steel 117STZ001154
    P/N 117TIZ001159 - titanium version of w/diver's extension steel 117STZ001159
    Smaller/shorter 2-4mm (3-position) micro-adjustable steel 117STZ004666 does not seem to be available in titanium
    P/N 124TI3307 titanium screws, and
    P/N 128ST0166 steel pins

    Conspicuously missing are the clasp links. The reason is that they don't exist for the "Bond" bracelet. My research also concluded that titanium clasp links for the "Speedmaster style" Ti bracelet affixed to the ref. 2232.80 Seamaster Titanium "Electric Blue" are also nonexistent.

    This info may.have changed as it was over five years ago. The only hint of a part that I ever found was P/N 118TI1515 for the titanium "Bond" bracelet but it is not in the catalog.
