STORM watches may have various features such as a simple analogue time display with date or more complex features. A Multi model has a number of small dials on the face and displays the seconds, day and month. Other multi dial watches are chronographs, with a large hand acting as a stop watch function, but also usually have a date function. Other models feature dual time, the STORM Technolight (torchlight), tachymetre, compass, temperature gauge, and unusual features such as flip up covers, shutters and rotating cases. Instruction leaflets are supplied for watches with features.
