Care tips for watches
Wear- and Care-tips for watches
|
A watch is a masterpiece of fine mechanics and high precision electronic, which should show the correct time reliably for a long period.
Guarantee claims expire by faulty use, breakage of glass, improper battery exchange, unauthorised interference and similar things. In case of a warranty claim you need to provide the proof of purchase and the certificate of guarantee; please keep both carefully. Notes for the handling of watches: Protect the watch from magnetic fields, strong heat, collision, mechanical abrasion, chemicals and water. For sleep, the watches should be deposited. Waterproof In order to meet demands on the waterproof, there are special constructions with gaskets. These gaskets are subject to a natural ageing process. They are affected by e.a. sweat and acids. Waterproof by DIN 8310 is a design feature, which can be challenged by a collision, temperature fluctuation and the influence of fat, bases and acids. A watch, which is being used for diving and swimming, should be especially kept and taken care of and its waterproof should be checked by a specialised dealer once a year. The watchcases are composed of several different, accurately fitting materials, which have different coefficients of expansion under temperature fluctuation. Waterproof is not an everlasting attribute. It should be checked yearly, especially before the loading, because the installed sealing element may fade in its function and daily use. The limiting value of the capacitance of a watch is measured in bar. Please note that the pressure data on the watch does not admit to conclusions on the diving depth. Especially when jumping in the water and while swimming, shortly higher water pressure than the guaranteed pressure value can be set the gaskets. Extremely at risk are watches, which are suddenly cooled down by a jump in the water after a longer sun bath. While striking the water surface, the pressure adds with the sub pressure caused by the rapid cooling down and can lead to light damages. The following table shows the recommended limiting values.  When an accumulation of condensed water occurs (films or little drops beneath the watch glass) the watch should be brought to a specialised watch store for repair, so that the moisture cannot leave any damage. The battery endurance depends on the construction of the clock unit. If a battery-powered watch stands still or shows the decrease of the battery voltage, the watch should immediately be brought to a specialised watch store, so that the flat battery cannot cause damage to the watch nor harm the environment. A battery change should be done at intervals of one to one and a half years at a specialised watch store. When changing the battery, the condition of the gaskets should be checked and defect gasket should be renewed. The cap should always be impressed, while wearing the watch, and be screwed tightly if possible. When depositing analogue watches for a longer time, the cap should be drawn to save power and to raise the battery endurance. The wristband of the watch is an expendable item, which especially with leather (natural product) is very vulnerable. Mainly sweat, chemicals, moisture and abrasion raise the wear and tear effect. Therefore it has only a very limited durability and should be renewed for hygienic reasons, at intervals of one to two years, depending on the wear-time. Also spring bars and other holding pins should be checked and if necessary renewed, when exchanging the wristband. |
