Not sure if this have been discussed before. Anyway, I am doing my research on A384 Revival, my particular interest with this model is the utilization of a screw-down caseback. I have never been a fan of the production chronomaster's little screws fitted caseback, that was a big concern stopping me from shopping for an El Primero. Meanwhile, both a A384 Revival and a Chronomaster have a pull-out crown IIRC?
But then, I am surprised to find out that A384, despite of the screw-down caseback, actually has a lower WR rating (5 bar) than Chronomaster (10 bar).
Has any member taken a closer look to these two yet? Is it more o-rings on the crown/pushers for the chronomaster, or simply Zenith is playing it safe and rate the A384 very conservatively this time?
I know that according to Zenith official website, their 5 bar WR is already sufficient for swimming, while 10 bar WR is apparently good for "any water sports". But my WIS part of me still wants to understand how it works, for a peace of mind.
Welcome any inputs!
