Many fashion and department stores offer a variety of less-expensive, trendy, " costume " watches usually for women , many of which are similar in quality to basic quartz timepieces but which feature bolder designs.
In the s, the Swiss Swatch company hired graphic designers to redesign a new annual collection of non-repairable watches. The zero-gravity environment and other extreme conditions encountered by astronauts in space require the use of specially tested watches. The first ever watch to be sent into space was a Russian " Pobeda " watch from the Petrodvorets Watch Factory. It was sent on a single orbit flight on the space ship Korabl-Sputnik 4 on 9 March The watch had been attached without authorisation to the wrist of Chernuchka, a dog that successfully did exactly the same trip as Yuri Gagarin, with exactly the same rocket and equipment, just a month before Gagarin's flight.

The International Organization for Standardization issued a standard for water resistant watches which also prohibits the term " waterproof " to be used with watches, which many countries have adopted. Water resistance is achieved by the gaskets which forms a watertight seal, used in conjunction with a sealant applied on the case to help keep water out. The material of the case must also be tested in order to pass as water resistant. None of the tests defined by ISO for the Water Resistant mark are suitable to qualify a watch for scuba diving.
Such watches are designed for everyday life and must be water resistant during exercises such as swimming. They can be worn in different temperature and pressure conditions but are under no circumstances designed for scuba diving. The standards for diving watches are regulated by the ISO international standard. The testing of the water resistance is fundamentally different from non-dive watches, because every watch has to be fully tested.
Besides water resistance standards to a minimum of metre depth rating ISO also provides eight minimum requirements for mechanical diver's watches for scuba diving quartz and digital watches have slightly differing readability requirements. For diver's watches for mixed-gas saturation diving two additional requirements have to be met. Some watches use bar instead of meters, which may then be multiplied by 10, and then subtract 10 to be approximately equal to the rating based on metres.
Therefore, a 5 bar watch is equivalent to a metre watch. Some watches are rated in atmospheres atm , which are roughly equivalent to bar.
There is a traditional method by which an analog watch can be used to locate north and south. The Sun appears to move in the sky over a hour period while the hour hand of a hour clock face takes twelve hours to complete one rotation. In the northern hemisphere, if the watch is rotated so that the hour hand points toward the Sun, the point halfway between the hour hand and 12 o'clock will indicate south.
For this method to work in the southern hemisphere, the 12 is pointed toward the Sun and the point halfway between the hour hand and 12 o'clock will indicate north. During daylight saving time , the same method can be employed using 1 o'clock instead of This method is accurate enough to be useful only at fairly high latitudes.
