While it's nearly impossible to reach these people by phone, they are very prompt in answering emails, which helped me (a noob)  a LOT with their winders.
Just an FYI for all Rolex Perpetual date Just watches,these watches require a 650TPD setting, that means to keep it fully wound you will need to keep it on 4-2448-TPD(if you sleep 7hrs a night with your watch still.) or keep it on 1-for 24hrs per day.
If you are fortunate to sleep 8, divide accordingly.
Only had it a couple of weeks if that, but I cannot hear it at all,sometimes I wish it would emit a stop and go beep,to be honest I d not see how it can turn even 650TPD on 1,as it seems like these need to be made to run continuously approx 20-30 mins at a time during the night to ensure a 100% wind.(you cannot over wind a Rolex),and according to mt Rolex Authorized Service Center it makes NO difference what direction it turns to charge the mainspring.
