Has anyone tried drilling a THIRD adjustment hole in the clasp for enhanced adjustment range? Would a third hole even work with the design of the new push-adjust clasp?
No.
If so, what would the diameter of the hole need to be to match the OEM holes?

Anyone had any recent success? If so, mind sharing where?
I had the updated clasp installed at Brent Miller Jewelers in Lancaster PA a few months ago (they are listed as an Omega Boutique) They adjusted the bracelet length with links so the clasp in the shorter position is my "normal " length, very comfortable 90% of the time. The extended position works well when my wrist swells slightly on hot days. Not a lot of adjustment, but suits my needs. I find the new bracelet very comfortable as I wear it daily, the small adjustment, now easily done, was definitely worth the investment. They were most accommodating and friendly, they have a lot of Omegas on display, including the Gold variations of the Speedmaster and some Seamasters. They indicated that the 3861 Sapphire Sandwich was their bestseller and the updated bracelet and clasp has been a part of that popularity.

The new clasp does not offer any additional adjustment positions. There are two positions on both the original clasp and on the new clasp. As best I can tell, these two positions are the same. That is, after having the new clasp installed on my watch and set to the same position, it fit my wrist exactly the same.

Thanks! Is this everyone's experience? The new clasp with easy adjust is the same dimensions as the original so that it fits the same exactly as the original clasp (i.e. not tighter and not looser)?

The new clasp is slightly longer, haven't noticed that being a problem, does require a length adjustment of the bracelet. The Jeweler was able to install the new clasp and maintain the same length that was comfortable before. I'm presuming they removed a link or two, I have a plastic zip bag that I keep in the original box with ALL spare links, screws and pins, now also has the original clasp, I save everything, ya never know.

Interesting! The reason I ask is the original clasp (without the easy adjust) fits perfect. So I wondering if Omega engineered the new clasp so that it provides a mathematically exact fit as the earlier clasp. So if the new clasp is longer, and one removes a link to accommodate, does this end up providing the same exact wrist opening as with the older non-quick adjust clasp?

I just don't want to go through the hassle of getting the new clasp and find that the fit is slightly tighter or looser than the original!

I don't think Omega went through the mental gymnastics to ensure the bracelet is the exact same length with the new clasp, it'll be close but it might be off a mm or so. If the old clasp fits perfect for you why even bother with the new clasp?

I like the idea of the easy adjust capability. It's a "nice to have" when wrist swells or contracts on hot, humid days or cold days...

My 3861 did not come with the adjustable clasp, but I didn’t need it because the links are small enough to make it fit me perfectly. I ordered the bracelet with the new clasp for my Speedy Tuesday just to see if it worked better. It was not worth it to me. You have one link space that slides out, that doesn’t really work to make a good fit when your wrist swells.

You're right, you only have two positions. So in my case, it would be more convenient if my wrist shrinks in winter vs using a pin tool. Not sure why Omega didn't put 3 adjustment positions in the clasp vs only 2.

Maybe the clasp would have been too long to accommodate the positions with it being so narrow. Who knows?

I visited the same Omega Boutique again today having decided to just buy the clasp kit and see if it works. I felt like I had seen enough evidence online that it should work and while $264 is not nothing to me, it’s a loss I would certainly survive if it didn’t work.

This time I had my Speedy with me. I went upstairs to the service desk. There was a different Associate at the desk, someone I hadn’t spoken with during my previous visits. I explained what I wanted. He was happy to help. I gave him the part number for the clasp kit. He took my watch to the back room. A few minutes later he emerged and my watch had the new clasp installed. Easy!

In fact, the gentleman in the white lab coat also came out and talked to me for a bit. As before, he was gracious and took the time to answer my questions. I didn’t feel the need to crow “Aha! You told me last time it wouldn’t fit my watch!” I think these guys are sincere in trying to help customers. My overall experience probably reveals some residual confusion among the Boutique staff from the days before this particular clasp kit became available and customers were unsuccessfully trying to fit the Chronoscope clasp onto their Speedmaster Pro bracelets.

There are two benefits to the new clasp that I can discern:
1. Adjusting the clasp between its two settings is done via a push-button instead of requiring a spring-bar tool (or toothpick). This makes adjustments much easier on-the-go.
2. The top part of the clasp (the cover) extends a bit further over the end-link to hide the “notch” that had become visible at the extended position on the original clasp. This makes the new clasp appear a bit neater when in that position.

The new clasp does not offer any additional adjustment positions. There are two positions on both the original clasp and on the new clasp. As best I can tell, these two positions are the same. That is, after having the new clasp installed on my watch and set to the same position, it fit my wrist exactly the same.

I do wish the new clasp offered more adjustment positions. Adding and removing links, with those microscopically small screws, is something I would only do at home under bright light with everything on a tray. More adjustment positions at the clasp would cover the sizing needs of more customers when on-the-go.

So, for me, this particular side quest on my watch journey is complete, with a good ending. Thanks for following along. The Speedmaster Pro is a fantastic watch. I hope you all enjoy yours as much I enjoy mine.

To close the loop, I was able to purchase the clasp bundle at the Manhattan OB. A big thanks to SalR for the tip!

The bracelet with the original clasp was phased out. Now one can only buy the 3861 bracelet with the new clasp from the OB. Did you notice any change in fit between the two clasps? Were you able to get an identical fit on the wrist with both?

Update: I ordered a clasp conversion kit from the Omega US parts department on May 23, with a projected delivery in 4-6 weeks. I called to get an update this week, and the new projection is mid-August.

There's no OB near me, and my local AD was weird about ordering parts in the past. So this seemed like my best option. Just sharing, in case anyone else is in the same boat.

Update: Out for delivery this morning. So 10 weeks to the day since I placed my order.

$264 (clasp) + $17.13 (tax) + $10 (shipping) = $291.13 (total)

Got my upgrade to the new clasp today as a surprise from my salesperson in the Boutique. Looks and feels quite good.

Did you have to remove or add any links to maintain the same fit achieved with the original clasp? Or was it a direct swap?

For mine, I removed one link, and it feels just slightly smaller when fully extended.
