The 1887 is a damn fine choice for the money, very much genlike, accurate, and under the radar. For over $500 the noob Daytona with a true clone 4130 and working chronos is a great example of the daytona to get. The navitimer is a cool watch but with flaws. There was some good Pams on the 7753 but not sure any of them are in production anymore. I wouldn't hold my breath for a timewalker either. I can't remember the last time I saw an accurate one for sale. The IWC 3777 is a solid choice and very close to gen. I preferred the older style balanced look with triple date but that's a personal preference.
