www.zeno-watch.ch Water Resistance
The water-resistance is guaranteed by several seals but cannot be considered as permanent protection. They are subject to a natural aging process and need to be replaced after a certain time of use. However, under certain circumstances, the integrity of the moisture resistance may become compromised within a shorter period of time.
Furthermore, impacts to the crown can influence the water-resistance as well.
A perfect long-term protection is given by annual water-resistance tests.
Water Resistance Classification
The "Water Resistant" mark has come to replace the "Water Proof" and is now described by the following ISO-Standard 2281:
Declaration on dial or back
NO DECLARATION
This model is NOT water resistant.
Any water contact should be avoided.
WATER RESIST
This model is resistant to minor and Accidental Splashes.
Greater water contact should be avoided
WATER RESISTANT 30M
(3 ATM / 100 Feet) *
Protected in everyday life, bathing, accidental splashes, short swimming or car washing - it is resistant against perspiration, water vapor, rain drops.
It is tested for water resistance up to 3 ATM, and must be able to survive 30 minutes under water at a depth of 1 m (3 feet) followed by 90 seconds under a pressure corresponding to 30 meters
WATER RESISTANT 50M
(5 ATM / 160 Feet) *
Protected in everyday life, bathing, accidental splashes, short swimming, car washing, parachuting, hang gliding and skiing - it is resistant against perspiration, water vapor, rain drops.
It is tested for water resistance up to 5 ATM corresponding to 50 metersWATER RESISTANT 100M
(10 ATM / 300 Feet) *
Protected in everyday life, swimming, snorkeling, mountain climbing, parachuting, hang gliding, skiing and all kinds of sports challenges
It is tested for water resistance up to 10 ATM corresponding to 100 meters
WATER RESISTANT 200M
(20 ATM / 660 Feet) *
Protected in everyday life, free diving without scuba gear, and all kinds of water sports.
It is tested for water resistance up to 20 ATM corresponding to 200 meters
WATER RESISTANT 300M
(30 ATM / 1000 Feet) *
Protected for scuba diving to a depth of 30 meters, for 2 hours.
It is tested for water resistance up to 30 ATM corresponding to 300 meters
WATER RESISTANT 500M
(50 ATM / 1650 Feet) *
Protected for scuba diving to a depth of 50 meters, for 2 hours.
It is tested for water resistance up to 50 ATM corresponding to 500 meters
* The metres value does not relate to a diving depth but to the air pressure
used in the course of the water resistance test. (DIN 8310, ISO 2281, NIHS 91-10)
We recommend to have your watch tested annually by one of our authorized Service Center’s, especially before summer holidays.
- To ensure water-resistance, gaskets must be replaced every 24 months a part of maintenance.
- If moisture has entered the watch, or it the inside to the crystal is fogged up and does not become
clear within a day, or sea water enters the watch, immediately the watch to a Service Center for repair.
- Avoid contact with water and dampness to prevent discoloration and deformation.
- Leaving the watch in such a state will allow corrosion to form inside.
- Accumulated dust and dirt may cause corrosion and soil your clothing.
- When you want bathing in the sea, always rinse your watch with warm water afterwards.
Condensation can appear in any watch and is caused by a sudden change in temperature i.e.
When a watch is removed from a cold room and placed into a warm room, or vice versa. The appearance of condensation does not mean the watch will not operate but it should be checked by us.
