Ditto panerai153's comments. What you have looks very good now. I cannot think of any gen parts that will be cost efficient in terms of their relatively high cost vs low improvement over your current parts. Yes, you can swap your bracelet, crown & xtal for gens, but, from an arm's distance, I doubt I could tell the difference & I am pretty familiar with them. On the other hand, if you have the financial (& testicular, if building your own) wherewithal to enter the V72-powered arena, I would start from scratch, gathering as many gen parts as you can find/afford & either keep (as a back-up) this watch or sell it.
