Omega 125 anni - 378.0801 advice

Hi, need some expert advice on the 125'.

I like the 125' a lot. Big, chunky and out of this world - and beyond... 😎

I 've got an offer on this, but so far as I can se is.-

-The dial an Omega service dial. (so I think)
-Bracelet 3033/213 and not the correct 2112/212 (asked the seller)
-Caliber 1041 (so seller says, but will revify when I see it)

I love the watch and the case seems in great shape.
But should I be cautious when not completely "factory" original, or just be happy with the fact I like the watch as it is?
The price is approx. 2200 euros.

-Thanks for your help!
