ive only worn 2 tourbillons in my life. a RD and a JLC. its quite the feeling.
youll have to ask akatsuki about that one.
I agree with New. Getting a minute repeater/Sonnerie cheap will a exercise in futility. The sound won't be as good, the maintenance will be an issue, etc. Cheap being a relative term, 100K isn't cheap, but it is for a MR/S. I think the best watch complication is the chronograph. Most useful, looks cool and is relatively affordable. A Omega Speedy Pro is a great watch with a classic movement that is quite reasonable. Then again, I wear a Tissot T-Touch as an everyday watch. It has all the functions I need and more, totally accurate and titanium(very light). It's not mechanical, but I like it. I also have a vintage Vacheron sub seconds which I use as a dress watch. Along with a few others.
No disrespect to G&B, but they can't compare to JLC on an horological basis. Just think of these beauties; Gyrotourbillon, Spherotourbillon, Master Tourbillon
If the big brands don't do it for you then the only way to go IMHO is with the independents as the earlier KV post helped demonstrate
