The mechanical movement is just that, where it functions because of a machine and not a battery. So to try and help I would like to explain the mechanical movement and how it pertains to you, skipping most of the technical talk that even sometimes goes over my head.
The watches sold and shipped out from Watch Chest are held to Rolex factory standards and expectations, but – to be completely honest – I’m not sure what these specs would mean to you if I just sat here and gave you a list of what’s inspected and required of a Rolex before a sale. It’s not that the customer is annoying at all, but I would get frustrated that their lack of knowledge would cause a rift in the experience of owning their Rolex – because usually there is nothing wrong and they are just unaware of how a mechanical Rolex watch works.
These are statements I’ve heard in the Watch Chest office and it can get quite annoying.
