Good day everyone,
Does anyone know if steel bracelet of Speedmaster '57 chronograph 38.6mm (The 1957 Trilogy) can be fitted to FOIS Speedmaster Moonwatch Chronograph 39.7mm without any modification? Thank you.

Well Adam @ LewisWatch told me the Trilogy bracelet will fit perfectly on the FOIS (bracelet part # 020STZ006241). My OB ordered one for me, but I won't be able to swap it on for a couple months.

I've read on these forums the FOIS cannot get a hesalite crystal swapped on without machining the case, but that's not true. Adam replaced the sapphire crystal on my FOIS with hesalite and it was direct with tension ring and can be switched back no problem.

Please post pictures and an update if this works. Thanks.

Will do. I plan to make a thread in about 8 weeks (July 4th weekend) when I get to see it in person for the first time as I'm out of town for now. Lug to lug the FOIS is supposedly 47mm while the Trilogy and Speedy Pro watches are 48mm. The Trilogy lugs are visually longer to my eye as well compared to the FOIS which points to it not fitting if the pinholes are the same distance to lug tip. The end links on the Seamaster Trilogy are different (shorter) than the Speedmaster so I may have to tell my OB to get that one instead of the Speedy one and try install first before spending $720 for it...

@nismo what are your plans with endlinks? I have been looking for a bracelet solution for the FOIS as well. A lot of threads on this forum has led me to the Omega 1125 with either 560 or 617 endlinks. I like the trilogy bracelets much more! Please do update us on your bracelet. Thanks in advance!

I bought my modded FOIS from Adam @LewisWatch. He said the 60th Speedy Trilogy will fit no issue (including endlinks). So for now my OB has that bracelet in stock waiting for me when I get back in town July 4th.

Per my conversation with Adam:

"The best bracelet to suit the FOIS is the one from the 60th anniversary Speedmaster. The part number is 020STZ006241 This bracelet will fit perfectly and looks relatively period correct without being too fragile for daily wear."

I'll let you guys know if it works or does not, but I may ask my OB for a Seamaster Trilogy bracelet to be in stock as a backup if the Speedy doesn't work. Only takes a couple weeks for them to get in. Price for that part number I listed is $720 USD excluding sales tax.

Here is a Trilogy Seamaster bracelet on an original Ed White. I know the FOIS case is different, but there is some hope.

The endlinks on the three Trilogy watches are different based on that photo I linked above with SM vs Speedy.

Just found someone fitted an Aqua Terra 19mm bracelet to FOIS! Not sure if this is workable or no any modification needed. Anyone tried that before? Thank you.

It looks like an original 7912 bracelet with #6 end links.

Edit: it's a 1035 with aftermarket #6 end links per him in an IG post.

Hi Bro, hope this msg finds you well! Hopefully you will tell us a good news about fitting the Trilogy Speedmaster bracelet to your FOIS. Can't wait! 😉

About to start a thread on it...it does not unfortunately. I just came back from my OB. He said the #6 endlinks are about 1.6 mm too short and would not abut the case securely. It would need the pin holes redrilled and I am definitely not doing that. 🙁 However, we may have a new 19mm bracelet available from Omega once the new 321 releases and there is a SS version. 😀

That Trilogy bracelet is absolutely gorgeous up close. I was heartbroken seeing it in between the lugs on my watch and not lining up correctly.

Thank you very much for sharing your findings, and sorry to hear that the end-links did not fit into the FOIS.. You are right, i won’t re-drill the end-links too. Really don’t understand why Omega always
making different end-links for Speedmasters. i had a bad experience on changing the bracelet (1171633) for my ST1.. Hopefully there will be a workable new bracelet that is similar to the Trilogy’s. Good luck everyone!

Hi everyone, I dust the thread to tell you that my jeweler has confirmed to me that the 19mm stainless steel Speedmaster 57 bracelet (60th anniversary) fits perfectly to the Speedmaster first omega in space FOIS the shape of the case back is the same.
