路Slightly better rate? I guess that's one way to loom at cutting the deviation more than in half...馃う
From an engineering standpoint, this is an incredible achievement. Unfortunately, majority of buyers will see it as 2s vs 4s - it is not life changing. Let's see who will challenge this accomplishment by Omega...

路Will the Spirate system be Omega only serviced?
If so,I see increased service costs.

o.m.e.g.a
路In case of a Spirate-enabled watch the "master chronometer" certificate has a revised "test limit = 0/+2 s/d" for test "Average daily chronometric precision of the watch".
Different limit is nothing new. "master chronometer" certificate already had different test limits depending on movement size:
0 to +5 seconds per day for movements with a diameter greater than 26 mm
0 to +6 seconds per day for movements up to 26 mm and over 20 mm in diameter
0 to +7 seconds per day for movements up to 20 mm in diameter
Now they just added another technical/technological factor that influences test limits.

路I just checked my two METAS certificates. 3.1s for the Apollo 11 50th Speedy pro and 4.1s for the sapphire Speedy Pro. Life will continue, lol.

路From Omega's press release;
"The innovative solution was a totally new Si14 balance spring which allows the watchmaker to act on the stiffness of the hairspring鈥檚 attachment point through an eccentric adjustment mechanism located on the balance bridge."
That's intriguing, although not being a Materials Sciences guy, I'm not real clear on how to interpret, "act on the stiffness of the hairspring鈥檚 attachment point". And so this does what, precisely? In some way changes the oscillating frequency of the Si hairspring, I would gather, but don't really have an understanding of what's going on at a mechanical level.

路路Omega Qualified Watchmakerso Omega can use lower grade techs?
This is a strange place to go with that conclusion. These watches aren't any easier to service than others - they still have all the same parts that all the others do, including weights on the rim of the balance for gross adjustments to timing. All the same skills will be needed for the new movement as were needed for the old...

路The tech at the nearby Omega boutique (they're closed) would regulate free-spring balances.

By adjusting the tension of the spring, you can make small adjustments to the frequency of the balance system, which in turn will affect the rate.
E.g. A stiff spring will not have much "give", so it will oscillate slightly faster. A soft spring will have more "give" and oscillate slightly slower.
It is another way of regulation besides the inertial screws on the balance wheels.

路From the exploded schematics, it looks like the extra screw will slightly increase or decrease the tension of the balance spring via the flared out bit.

路As this affects the rate in all directions somewhat equally, it's not helping to reduce delta. Unlike the Si14, it doesn't improve thermal, vibrational, nor isochron issues. It seems to only simplify the task of regulating.
You effectively added a regulator screw like in the ye ol' movements without compromising the free-sprung mechanism.
Looks like it offers finer adjustments in addition to the inertial screws on the balance wheel.
