In the place where I grasped how to handle Lew's, I explain laying upon of concrete time. The procedures of the laying upon of the time are as follows.
 I leave Lew's open
In the case of a clock of Rolex, most adopt threaded Lew's. At first let's cancel rock to be able to draw Lew's.
The lock comes off because of the state that I added a watch to when I turn Lew's several times in this side side (counterclockwise direction). Please be careful to pull it by force here, and not to be going to take it off.
 I pull Lew's
If a lock comes off, I pick up Lew's and pull it. Because we can do it in the state of the pull, let's do two steps of adjustment of the time in the state that we drew to the maximum.
In the case of a non-date model, one phase is all right if I draw it. Because there is not it, the second phase, please be careful not to pull it by force.
In addition, let's draw by one phase in the date model. It is NG to draw two phases at a stretch. Because it causes the trouble, please avoid it.
 I adjust the time
I adjust the time if I draw Lew's.
I turn Lew's counterclockwise to put the time together. Please adjust it when you turn it counterclockwise because an hour hand, the long hand advances clockwise.
In the case of a date model, a date changes at hour hand 2 rounds.
In addition, it is repeated, but prevent Lew's from turning in reverse. I will put a burden on a clock and cause the trouble
 I push the Lew's and go back up
I turn it clockwise and lock it while pushing the Lew's if adjustment of the time is over. Let's completely lock it so that water and dust do not enter.
In addition, it is necessary to push back two phases in the date model. I push back by one phase, and let's be careful not to put a burden on a clock.
