Trying to build my dream Speedmaster: Mitsukoshi dial in Schumacher Legends case

Up front I want to apologize that this might offend some of the purists here, but I hope some of you will be able to forgive me and will help me with advice and knowledge.
After receiving my first Speedmaster 3594.50 I have gotten seriously bitten by the Speedmaster bug.
And while I truly enjoy wearing it and don't mind the daily ritual of winding it, the fear of getting it wet is a problem when you live in a sub-tropical climate and just need some cooling off during the day - aka a dip in the pool.
Hence I started researching other Speedmaster models with better water resistance (the Broad Arrow with it's 30m being the bottom of the totem pole).
And while the newer versions promise improved aquatic performance, they are incompatible with my second itch: a panda dial (preferably a Mitsukoshi, or Apollo 11 35th anniversary) and I actually prefer the 1861 case shape over the 3861.

So while researching the subject I find out about the Michael Schuhmacher Legend series (specifically the 3507.51.00) and it's 100m water resistance.

While a beautiful watch in itself I would still prefer a less busy panda dial instead.
But it felt like the best of both worlds: classic 42mm Speedmaster case and improved qualities as a daily watch
So I looked into the respective movements and they seem very similar in proportions:


Both are 27mm in diameter and 6.85mm or 6.87mm in height.
And my improvised measuring attempts on the computer screen seem to put the subdial centers also in the same locations on both movements.
So I feel a 1861 panda dial should fit the 3301 movement as long as the date wheel is not interfering with the dial.
And with the 3507.51.00 I could even reuse the same hand set (the red seconds hand tip would even make the Apollo11 35th anniversary dial work)
I realize that I have to sacrifice the dial feet but I could live with that if it means I would get my dream watch otherwise.

This could be "THE ONE WATCH" for me

And I have a 2025 GMT Master II Bruce Wayne that I am not really warming up to and which could help get this project off the ground 😀

I would love to hear from the more experienced Omega connoisseurs if this wouid be feasible or if I have overlooked something.

PS: Potential future upgrades could include a lumed sapphire bezel and a low profile display caseback (both from Sidewinder). I have the caseback on my 3594.50 and it brings the watch significantly closer to the wrist:

3594.50 on Watch Steward original series

As will a bracelet with female end links:

3594.50 on Uncle Holzer with upgraded clasp

Both are about 27mm diameter movements but they're going to be different in thickness and the relative placement of the crown and pushers relatively to the case is likely to be significantly different even if it could fit.

Another alternative in the Panda dial with more water resistance might be the FOIS models:

Thank you for the suggestion. I did try on the FOIS and unfortunately it doesn't wear as well for me as the Professional case.
As for the crown and pusher placement: I was under the understanding that the case of the Schumacher Legend is basically the same as the Professional case but I might be wrong there.
I almost feel like I have to bite the bullet and get all the parts involved and give it a try.
Worst case I can always put the Mitsukoshi dial in a newer 1861 case and live with that.
The Schumacher is growing on me more and more anyway but you got chase dreams every once in a while...

I wonder what makes the Schumacher case so much better in regards to water resistance?

I guess I meant the professional case with the lyre lugs. It just hugs my wrist better.

Has anyone ever tried to fit a 1816 dial to a 3301 movement?

I am talking about the 42mm Speedmaster Michael Schumacher Legend series, as you can see from the picture above.
NOT the Reduced version

I took a picture of a 1861 dial and overlaid a picture of the Schumacher Legend and then showed different levels of transparency:



Looks pretty close to me in regards to subdial positions.
What do you think

Do what I did and ask google if the sub dial post positions are the same for the 1861 and 3301 movement. The answer was an unequivocal no. Though AI isn’t always to be trusted it’s true. Close isn’t good enough unless you want to butcher the holes on your new dial to make it fit.

I got a similar reply but it also said that the subdials should be farther spaced and I just don't see it.
I made a little video of the overlay sliding back and forth and to me it really looks like the holes are lining up:


Sorry for the background sound: one of my dogs is a big snorer 😀

I guess only one way to find out 😀 Gonna have to bite the bullet

Yes I will have a regular 1861 dial to try it out first.
Worst case I end up a with a very nice Schumacher and a Mitsukoshi with a 1861 case 😀
