Available in diving watches, a screw down crown is a special feature which aids in water resistance. This type of threaded winding crown screws tightly into the case and protects the case from any form of dust and water. The crown has gaskets which create an air tight seal when it is screwed in. It was invented in the year 1926 and tested in 1927 when Mercedes Gleitze used it while swimming the English Channel. The screw down crown protects the watch from water and dust. While the wearer should always make sure the crown is left in the locked position, it can easily be used to set the date, day, time, etc. To change the settings, release the crown by turning it in a counter clock wise direction, towards the 6 o’ clock point. The stem will be extended and you can set the time, date, day etc. To lock it again, ensure the stem is pushed all the way in and turn it in a clockwise direction.
