A watch doesn't need to constantly be in motion in order for the lubricants to properly circulate - even giving it a wind every month or two should be enough, and this is becoming increasingly less necessary due to advancements in lubricant technology. However, in regards to the watches that you see in the stores, they typically sell long before any possible issues arise. Additionally, the watches you see in stores typically do receive motion - whether it is while a customer is looking at it, or even just at the end of the day when all of the watches get put back in the vault for security purposes when the shop closes.
