Service estimates SMP 300 2531.80?

[Carusoracer]

Hello,

New to the forum and new to me, a vintage SMP 300 reference #2531.80
Question: What would the typical repair estimate be for the watch?
Caliber: 1120 6,000,000 serial number 60000000’s?! 2001 date per warranty card.

The watch runs +6 seconds per minute fast, until about 12 hours later it starts running 16 seconds per minute faster and runs out of power reserve in 33 hours.

Great lune on the hands, indices, clear crystal, wave dial nice patin , and good blue bezel. The scalloped moving outer bezel has a couple marks at various points, while the bracelet is clean, normal stretch, most of the desk dives marks etc have been polished lightly all over the entire piece at one point in it’s life.

Would like to have the bracelet replaced, along with the bezel and most importantly a new main spring installed, oiled, overall maintenance of the running gear.

Any thoughts and relative service period, price, returned to me from Omega USA? I’m here the US.

Thanks in advance for your assistance.
