Yes the 32 has a greater power reserve by making the spring-barrel thinner,and ball bearing rotor, but will they be more accurate than the 31 series IMHO doubtful.All this Chronergy escapement, 10 14 patent description stuff is mainly clever marketing.Basically yes the new movement has some improved features, but its still based on the older 30 series movement. All of the Rolex movements have proved themselves over the past 50 years with there robustness and accuracy.And the main Achilles heel in most of the Rolex 15 and 3 series movements like the cal 3135 cal 3185/6 was the rotor shaft bearings. and IMHO it's the 15 and 3 series movements weakest link the rotor winding sleeve bearings. Now these needed proper lubrication and its very critical its done right,if it dries out especially in warm climates you will get severe wear in the bearing jewels.Looks like to me Rolex has sacrificed a bit in the engineering department for better winding efficiency. IMHO the small diameter winding post don't offer enough support to the rotor weight, but again some go on for decades without service, but many fail for the lack of.But already on forum some are already moaning they can hear the rotor noise on the 32 series I guess you will never please everyone regarding Rolex watches.

Anyone who complains about rotor noise then can not lust over the Daytona. The 4130 has the same ball bearing noise. Which btw I think at least is a non-issue. Thanks for the good info
