Still rolling with the 321 Ed White which I've had for 10 days. I've had many Speedmasters over the last 48 years and this is probably the nicest one overall, in my view. You get all the styling and mechanical cues of the 60's models from NASA's heyday in a modern construction, and there will be zero issues with ever servicing the 321 movement. Just a joy to wear, worth every penny for the price paid.
