A lot of people locate it peculiar that, whenever the water pastime enables you to purchase a watch, why endorse them waterproof watch above 100 meters. "I did so not jump forever greater than 50 meters," a dive tutor say considering the contributor. Not know why, though in fact, this question is not only present in the general consumers buy watches, watches a few years ago the majority of the master repair and salesman of the watches are also very concerned about this issue, until recently the market movement is taken seriously, began to pay attention to water mark distinction.

Once the water deepness elevated by 10 yards, it will increase the same in principle as an individual ambiance burden. So that the general watch factory are pressure gauge to test the watches are waterproof, according to this principle. So some watch factory will be marked compression values, namely unit marked bar or atm, to represent the value of its water. 1bar is equal to a particular kilogram every different square centimeter survive pressure, it might tolerate the stress on the pressure 10bar comparable to a level of 100 yards beneath the water top that exist, pressure 20bar water equivalent to 200 m. Compression 3bar 30 m water similar, which commonly known as the existing water. Quite often watch the most popular challenge is only labeled "Water Amount of resistance" without the need for water symbol values, the reality is as outlined by world wide guidelines are regarded as to water resistant 20 m.

But why ingredients label interesting depth and then the actual usage of this sort of a big difference? First of all, the general so-called stress tests are just a static measurement, within a few seconds the pressure reaches the pressure data can be marked, but the actual wear on the user watches Shell is exposed environment is dynamic. If engaged in scuba divers, even if only within 30 meters of recreational diving, in a short time and under rising latent as frequent as in compression, decompression changes, hand is generally the most frequent site of human action, whether or water activities of daily living, physical action often substantial.

Besides, the general public does not watch regular maintenance or cleaning habits, although time in the sun and raindust, dirt and rain will make waterproof apron inside the case the case even aging itself over time. Also evaluate water watches is generally followed sampling structure, every one batch extract only a couple of manufacturing facility assessment verdict. This really is the brand's durability

Have very good importance, I have viewed a creation labeled 200 yards water resistant scuba diving watch vendors, confessed getting a demand evaluate meter can only evaluate to 10 atmospheres.

So, according to simple test at the factory and then deducted the safety factor of many times, over the years most of the watch factory also see this as a matter of course, and still in use up, the above considerations, considerations should be waterproof case.

First, dive watches requirements designed to waterproof it can actually be placed in the water at least 100 meters, and subject to the following requirements before called diving watch:

1, with the pre-determined time means that: as a way to ignore unintended rotation, and the right use through plunge and maximal interesting depth. This means that every last five minutes ought to alange sohne Watches be properly designated. In order to resist accidental rotation, they are mostly designed to only rotate counter-clockwise, generally the most common is the timing of the outer ring.

2. Profile: 25 cm space at night, always observed while using time based on time indicator suggests pre-picked time configuration, that will ensure the watch remains functioning.

3, the magnetic amount of resistance: with magnetic potential to deal with hold up against 4800 amperes per meter (DC 60 Gauss (Gauss)) of the aforementioned.

4, surprise resistance: can stand up to 1 gauge tumble elevation of impact.

5, sodium water: a day put into 23 ℃, concentration of 30 gr a liter of sea salt water, the outcome can not manage to transformation, and average surgical procedure.

6, with stress and strain reliability: placed in the water carrier, and pressurized into the situation around 1 minute 1.25 conditions the atmospheric force water-proof force designated, which enable it to tolerate roughly 2 hours.

7, the water circulation efficiency: range of 30 centimeters, the actions will not be disturbed (for instance the timing of a exterior band, lumination switches, et cetera.).

8, zero-jolt strength: a, lugs (strap after which you can location label) protected from 200 Newtons worthy of anxiety. b, water tension inside the water symbol of 1.25 conditions the stress in the pressurized unveiled 10 a matter of minutes after, the crown worthwhile resistance push vertical covering 5 Newton.

9, resistance to heat level transforms: 30 cm in water and built to stand up to 40 ℃ to 5 ℃ 40 ℃ 10 short minutes each individual abrupt improvement in temp. Ought not more than one moment intervals.

10, anti-anxiety, anxiety opposition: first, to the pressure to 2 bar pressure test. Then pressure test, placed in a container and pressurized water within one minute to the case of the water pressure of 1.25 times the indicated pressure after 2 hours, in order to reduce the .3 bar per minute way pressure relief for 1 hour so far. One example is, the reality noted waterproof 200 meters, you may need pressurized to 250 m.

Leap watches noted height is required to be an integer of a single hundred, and all of the tasks will need to be operating in this depth to keep its performs at least for that some specific time, similar to water-resistant 100 m shall be proficient at carrying 1 60 minutes daily at 100 yards water degree, water 200 yards will probably be saved 2 hours everyday ... et cetera. Eventually, whether the general characteristic needs to be known in helium-breathable oxygen setting, the watch may cause damage.
