Watch case: watch bezel, middle case and back cover
Watch bezel here we do not discuss the shinning bezel, because if your eye is right, you can distinguish the good or the bad bezel, as to the dog teeth bezel, the teeth bezel also can be seen easily. For the middle case, you need to see the outer case under the nine o'clock position clearly, as it is the place which is easily scratched. Of course, it will have a film to protect it. The wiredrawing of the back cover also is the same and it also has the film to protect it. But i think the details should pay attention to if you want to have a ideal Rolex watch.
When it comes to the watch dial, there are also the disk and the pointers, and you just keep in mind to maintain it regularly so as to make your Rolex watch has a longer life. For the calendar function of the Rolex watch, most of them are the jumping calendar, that is to say, when it is 24:00 o'clock in the night, it will jump to finish the action of changing the calendar, and for the purchaser, you should try to use this jumping calendar function when you are buying the Rolex watch to see what will happen during this process, and it is ok when happening within ten minutes of 24:00 o'clock.
Although there will have the plastic film to protect the Rolex watch when you are trying the watch in the store, we cannot guarantee the watch we buy will surely be perfect, and we suggest you look at the watch chain and the watch buckle because when you use the watch normally, the watch buckle will be scratched easily, so according to our daily habit, just see the place which is the most easily scratched during our wearing.
