I would keep on saving a bit more for an IWC Pilot chrono - they are great watches and can be had for a good price pre-owned.
My advice would be not to worry about rotor wobble, when I used to have my LPP chrono before giving to my brother, the feeling of it moving as one wears it was actually most enjoyable (and something I sometimes miss with my diver) although it’s obviously different for other wearers.
It’s also a very widely used and reliable movement.
