Wich pocket watch to sacrifice?

[buddhabar]

Hello friends of the forum.
I ask you for advice on which of the two pocket watches to sacrifice?
Let me explain better.
I have a pam372 in which I need to replace the now broken clone P3000, and therefore I wanted to use an authentic Unitas 6497.
I have these two pocket watches (one of the Turkish railways) and (one of Buren) with identical Unitas 6497 movement from which to cannibalize the movement.
What do you recommend I dismantle? I was thinking of the Buren.
What do you think?

Here the photos:

Use the Buren, keep the one with the railroad case intact .

Any movement pics?
By the way, if you use the Buren, could I have the hand set?

a movement pic would be nice to decide. it's not easy, I like the simple case of the Buran but the dial of thd other one .
display CB?

Thanks to All...

Here the others pics.

nice case. as the movements are identical, I would use the better working one for the project. anyway you can keep the rest parts and however you like you can switch the movemen in the pocket watch case

Update of the two movements:
That of the Turkish railways abundantly exceeded 48 hours to reach approximately 53 hours, while Buren stopped at 46 maximum 47 hours.
Both I regulated them with a precision of about +/- 3 seconds a day in a horizontal position.
It is not unlikely that in conclusion I will use that of the Turkish railways.
I will do another proof of charge autonomy, to have a certain outcome.
@dj57 I'll let you know if the hands are available for you.
