Most individuals think it is different that, if the water pastime could be used to shop for a watch, why suggest them water-resistant watch more than 100 m. "I have done not dive for a lifetime of greater than 50 meters," a dive instructor say together with the author. In fact, this question is not only present in the general consumers buy watches, watches a few years ago the majority of the master salesman and repair 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, but not know why.
Whenever the water detail enhanced by 10 yards, it will raise the same in principle as an individual natural environment stress. According to this principle, so that the general watch factory are pressure gauge to test the watches are waterproof. So some watch factory will be marked compression values, namely unit marked bar or atm, to represent the value of its water. 1bar is the same as 1 kg every sq centimeter bear the pressure, it may possibly resist the pressure in the compression 10bar comparable to a interesting depth of 100 m underneath the water exterior that occurs, pressure 20bar water equivalent to 200 meters. Pressure 3bar 30 yards water comparable, which often called the life water. Normally watch the most popular scenario is only labeled "Water Amount of resistance" devoid of water level beliefs, the fact is in line with world-wide benchmarks are regarded to water-proof 20 meters.
Why tag height additionally, the exact application of this kind of a major 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 rain and sundirt, rain and dust will make waterproof apron inside the case the case even aging itself over time. Also try out water watches is actually adopted sampling product, each set get just a couple of manufacturing facility evaluation verdict. This can be the brand's reliability
Have awesome meaning, I had explored a producing labeled 200 yards water-proof plunging watch sellers, admitted making use of a force test gauge will only try out to 10 atmospheres.
So The above considerations, considerations should be waterproof case according to simple test at the factory and then Richard Mille Watches 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.
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, together with the pre-determined time would mean that: for you to stand against accidental rotation, and good use all through the plunge and maximum deepness. Meaning every single 5 minutes need to be distinctly noted. Generally the most common is the timing of the outer ring, in order to resist accidental rotation, they are mostly designed to only rotate counter-clockwise.
2. Exposure: 25 cm extended distance in the dark, nevertheless observed with all the time depending on the time indication means that pre-picked out time establishing, which enable it to make sure the watch is in operation.
3, the magnet resistance: with magnetic potential to deal with withstand 4800 amperes each meter (DC 60 Gauss (Gauss)) of the above.
4, impact reluctance: can put up with 1 meter lose stature of consequence.
5, salt water: a day placed into 23 ℃, power of 30 grams every liter of salt water, the actual situation cannot afford to transformation, and natural business.
6, placed under demand stability: positioned in the water compartment, and pressurized within the claim in just 1 minute 1.25 days the atmospheric anxiety watertight anxiety marked, that will bear as much as 2 numerous hours.
7, the water move results: interesting depth of 30 centimeters, the motions will not be seriously affected (such as the timing for the outside ring, light keys, and so forth.).
8, anti-surprise level of resistance: a, lugs (band and after that place title) protected from 200 Newtons worthy of pressure. b, water weight inside the water level of 1.25 moments the pressure for the pressurized emitted 10 a short time afterwards, the crown deserving opposition energy straight covering 5 Newton.
9, potential to deal with environment adjusts: 30 cm in water and after that intended to endure 40 ℃ to 5 ℃ 40 ℃ 10 a matter of minutes each and every abrupt alteration in heat. Should not more than one min times.
10, anti-strain, demand level of resistance: first to the pressure to 2 bar pressure test. In order to reduce the .3 bar per minute way pressure relief for 1 hour so far, 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. As an illustration, the outcome labeled water resistant 200 meters, you must have pressurized to 250 yards.
Plunge watches designated detail is required to be an integer of one hundred or so, and all features ought to be operation inside this height to take care of its characteristics at the very least to acquire a certain time, which includes water-resistant 100 m will be very effective at holding 1 hour or so each and every day at 100 meters water detail, water 200 m shall be kept two hours each and every day ... et cetera. At last, whether or not the typical attribute also needs to be observed in helium-fresh air natural environment, the watch causes harm.
