It’s 16 mm and adjustable. I like the fit of my 3861 Moonwatch bracelet, but wouldn’t mind having some on-the-fly adjustability. Has anyone looked into whether the chronoscope clasp will be available separately (I.e., without having to buy the entire bracelet)?

Wow thank you for this write up! I am going to call my boutique tomorrow and put an order in for this. Would be nice if Omega offered some kind of exchange program even at a discounted rate. Frustrating they would leave it out and then come out with this so shortly after. Not even about the money but makes the watch having felt rushed.

Just had my sapphire 3861 Moonwatch clasp updated to the Chronoscope clasp at an Omega AD.
Nice that the Omega AD just did the work in ten minutes without question (very different than how my Rolex AD responded to a similar non-standard request: "We are not authorized to do any non-standard work on any Rolex product."). The Omega AD that I ordered the parts from only said, "Substituting this clasp is non-standard, so these parts are non-refundable if they don't do what you want."

Note the required Chronoscope bracelet replacement link doesn't have the polished, narrow inner links that the sapphire bracelet has, however it's barely noticeable to my watch nerd eyes (probably already mentioned earlier in this thread).
2.3mm is a small adjustment for sure, but it's been better than no quick adjustment, and I'm happy with it.

Thanks so much to all the people that contributed to this thread !

Just to make sure you have all of the info, the Chronoscope bracelet link isn't actually required. You can just swap the folding arm from your old clasp to the new one and use your standard Speedy bracelet link if you'd prefer and maintain the polished bits. Works either way, totally your call.

Woops, I missed that ! A cheaper way to go too,
I ordered the parts when this thread was very short, possibly why I missed the approach of using the Speedy link, I should have checked this thread for updates after I received the parts. Using the Speedy link would have meant I could have easily swapped the clasp myself too I bet.
Thanks for your reminder, sir.

Actually I would recommend you to use both parts. Chronoscope deployant arm is intentionally widened to create space to fit around the adjustment push-button, furthermore it has an indentation to accommodate such button:

Wood Rectangle Tints and shades Metal Leather

Wood Reptile Terrestrial animal Eyewear Font

If you swap the deployant arm with the original 3861 one, there will not be enough space to accommodate the push button, leaving a small gap when the clasp is closed:

Sleeve Wood Collar Personal protective equipment Helmet

Note that the clasp will close securely, but the fit will not be perfect.

My issue here is that the chronoscope end-link is not available in all markets (Here in Spain, for example, the clasp can be obtained through the Omega Extranet, but not the end link).

Since I'm looking for alternative ways to ger that specific part (i.e. Part 118STZ013110), Can I ask the zone (e.g. USA) from where you sourced that?

Sure, it is probably ideal to use the arm which comes with the Chronoscope, but has anyone actually encountered any issues in practice from just swapping the Moonwatch deployant arm onto the Chronoscope clasp or is this just theoretical on your part?

It is from my personal experience swapping the clasp (that terrible picture from my previous post is my own watch 🙃 )

The clasp closes securely and, in my eyes, there's an inprovement with respect to the standard clasp (i.e. not weird gap when the second microadjustment slot is being used), but with the chronoscope link, the clasp would be "perfect".

I'm righ now in the hunt for the chronoscope link (i.e. Part 118STZ013110), since at least in Spain is not available through the extranet :-( ...If you do not want yours, I'll be more than happy to buy it ;-)

In addition, in this post from OF you can find further details about this topic (with much better photos than mine).

Here some pictures where hopefully it may be appreciated how the push button prevents the arm to completely fold into the clasp:

which leaves a small gap with the clasp is closed:

My Omega AD mistakenly said I needed two links, in addition to the clasp, so I have an extra one. IM me if you're interested.

Can someone direct me to an ad who can source the chronoscope clasp and any needed parts for the new speedmaster? The ad where I purchased the watch is unable to order this clasp. Thanks!

I got mine from Topper's (this sub-forum's sponsor). You may want to reach out to them to see if shipping to you is a possibility.

I already did- as that is where I purchased the watch! This was Jay's reply:
Apologies Avi,
We tried to use the chronoscope moonwatch clasp before. Omega won’t sell us the clasp attachment.

I'm lost now? what's going on? I ship to NJ not to Israel, so that's not the issue...

Just call an Omega Boutique. Whenever in doubt and unable to get any part from an AD just call a boutique or go to one.

I cannot get to a boutique as I'm currently overseas... can I just call and order over the phone and ship (to either Baltimore or NJ)? If you have done this and can recommend a boutique, I'd appreciate.

That's very interest! And I can't believe I never noticed this (as someone who has suggested swapping the folding arm). I'll have to take a closer look tonight because I'm curious to see it in person, but it definitely doesn't look like it's closing all the way. I'm very surprised the clasp secures at all with the button interfering with the arm. I guess I will be hunting down an accompanying end link now...
