I'm 99% sure there is currently only one 187 available despite different pricing from all of our dealers. Varying price depends on number purchased, number of middlemen, and the time when the dealer purchased. The only other version was the watchonpo version with old 21600vph 7750, AR coat , deeply engraved caseback and engraved "He" valve. I'm also 99% sure the size of the cases would be exactly the same.
As for the Super Avenger reps. The newest one Trusty has looks the best to me. The dial is a bit closer in my opinion but the hands are wrong. If I'm not mistaken though all of the SA reps still use the older 21600vph 7750 movements. Also the bezel pearl may be off, haven't seen very good shots yet. If I'm not mistaken its supposed to be Tritium encased under sapphire. However there are many improvements over previous versions. The case, bezel, crown, case back, and even the pushers all look amazing!
Both will be great looking sporty watches. TTK said it well on another thread. We were discussing a comparision of the Bentley vs. the SA. And we agree that the SA looks more like a tool than a piece of jewelry.
As for me. The 187 is in my watchbox and the SA is on my shortlist!
