First off all hello and congrats on your new watch and yes there are some ways to mod this watch.
Hand stack can be corrected using a A3187,Genuine 3185 to 3187 or you can ask your modder to build a Modded 3185 movement using a Yuki 3135 or SH3135 as a base movement parts inorder to make a SH3185 is gonna cost 500-700$ if i remember it correctly and SH3135 costs 200? (I'm not sure about the price of the Sh3135 or the yuki movement i don't want to misguide you about that.)depending on the place and from the seller you buy at the same time if you want to have a CHS (Correct Hand Stack) you will need to find a genuine handset from places like chrono24 or our forums modders can get you one. Bezel can be cleaned inorder to make it much more smoother i think. If you want to go to the franken route on the movement side of things it would be the best to get your date wheel changed as well and some parts with it to make it stable whole franken movement.

If you dedicated enough to spend the amount of the money for the movement and for the hands congrats and it would be nice if you replace the dial because of gen rolex indices at 12,6,9 are rounded but on the replica dial it is not and i adivse you to get a Xtal crystal or buy a genuine crystal fro chrono24
As i said earlier if your are dedicated for this project in order to get a sexy watch good luck and enjoy your franken watch.
Ps: There are modders at uk but sadly can't remember their account so sorry about that.
