I like the fast that the watch is totally a low-key travel watch in that not only can you use the chrono minute and hour subdial as a second time zone (one that can also show time zones that differ in 15min increments), but the watch also has a quick-set hour hand.

Back to the clasp topic, the above video confirms that the Speedy Pro will eventually get an adjustable clasp as well. The question remains will that clasp have the same width as the current Speedy Pro clasp at 15mm, or if it will be the exact same clasp as on the Chronosope, which is apparently 16mm.

I have good news galore. I got the call yesterday that the clasp I ordered was ready to be picked up. I dropped by earyl this morning with my Speedy Pro and handed it over to the OB's watchmaker. Unfortunately I was seated away from him, so I didn't see exactly what he did, which will become more important later.

The good news is that it fits the 3861 bracelet, the great news is that it is a perfect fit in terms of width compared to the bracelet! And the fact that the price was only CHF 200 was just the cherry on top. Even the SA was surprised seeing that apparently a simple pin buckle from a different model already cost CHF 250.

Anyways, there was a couple strange things which made me regret that I didn't see what the watchmaker was doing. First off, as you can see from the pictures below, the Chronoscope clasp (in all pictures the one attached to the bracelet) is slightly longer than the original clasp. When I came in, my 3861 wore slightly loose on my wrist. After the clasp was switched, with the new clasp not set to the extended setting, the watch fit tighter than it did on the old clasp. Yet the watchmaker assured me that he did not remove any links.

Another weird thing is that as you can see on the receipt at the bottom, there are two serial numbers for two parts. And the SA confirmed that there was indeed the clasp and an "attachment piece". As the watchmaker was gone at that point, I wasn't able to get a clear picture on what part the attachment piece was exactly. Also, for some reason the SA told me that they were not able to give me the plastic baggies that held the original parts. As you may know, these show the serial numbers on them. I've purchased parts from them before, and it's the first time they withheld the bags.

Anyways, the watch now fits me better than before, and I am glad to have a quick extension for those hot days when my wrist swells later in the day. I was also able to handle the Chronoscope and the Seamaster 300 while I waited, and both are great looking watches!

That looks great!

So now when they bracelet is extended, is the smaller connection area still covered by the top of the clasp?

I hope this picture answers your question. Left is not extended, right is extended.

Dang, thank you for the great reply and all of the pictures! I have to admit, I’m a little sad I couldn’t be the first to complete this haha. I’m guessing the attachment piece is probably just spring bars or screw bars, right?

I’m actually happy to hear the clasp itself is a little longer (figured it probably was). That should give me a perfect fit with the option of extending if needed. Thanks again!

I have no idea what the serial tz013110 refers to. What I do know though is that the last time I bought an Omega clasp, there was only one serial number for the clasp and another for the endlinks that I needed to fit the clasp to the 1861 bracelet. But this time there's no endlinks that came with it as far as I can tell.

I have a friend who is an Omega AD. I will ask him if he is able to look up specific parts numbers.

thanks for the confirmation that is it the same width as the moonwatch. The price seems a tad high for a clasp, but what are we going to do....a price we pay for being early adopters......

So for the US, which part number it is so I can order? O117STZ013899

I think that should be it yes. Or just tz013899.

thanks, I just saw the Omega receipt you posted....did u order 2 parts?

what is 118stz013110? the end links?

I have no idea what the other item is. It's explained a bit more in my posts.

I think Fratello has the width of the clasp wrong...did they physically measure it? Several people have already installed the Chronoscope clasp to their Moonwatch bracelet and it is is the same 15mm width.

I already ordered the parts (both O117STZ013899 & 118stz013110) with my AD, they actually called me today and told me it should be in next week. In addition, they told me if 118stz013110 is not needed, they can just return it to Omega at no cost to me. Didn't have to pay for the parts up front, they just special ordered it, and they will install it for me. I'll bring my extra links just in case it needs to be added after the new clasp is installed.

Lastly, WatchAdviser had an excellent video with Omega on the Chronoscope. I commented on why no quick release spring-bar on the ref and the moonwatch and he responded......."There will also be a solution coming to quick exchange the bracelets and straps..." Nice...

Please do post pictures of the 118stz013110 if you can - whether it's needed or not. I am curious to see what it is. I have the feeling it may have been a standard Speedy link that was added for free after the OB's watchmaker scratched one of mine while replacing the clasp. It's the only thing that makes sense to me.

Yes, but see the pic in post #22.

For the ones who did the swap with the new link/clasp, did it actually change the overall length of the bracelet ? Did you have to remove some links ?
It looks like the new clasp is a bit longer, but I was wondering if it's only the top part, or if it affects the length of the bracelet when installed.

New clasp is slightly longer. If I remember correctly, I removed one link from the previous setup I had.
