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.
Classifications
The “Water Resistant” mark has come to replace the “Water Proof” and is now described
by the ISO-Standard 2281: Declaration on dial or watch back.
NO DECLARATION
Watch is NOT water resistant.
Any water contact should be avoided.
WATER RESIST
Watch is resistant to minor accidental splashes.
Greater water contact should be avoided.
WATER RESISTANT 30M – (3 ATM / 100 Feet) *
Protected in daily life activities, bathing, accidental splashes, short swims or car washing – it is resistant to perspiration, water vapor, rain drops.
Tested for water resistance up to 3 ATM, and must be able to survive 30 minutes under water at a depth of 1 meter (3 feet) followed by 90 seconds under a pressure corresponding to 30 meters
WATER RESISTANT 50M – (5 ATM / 160 Feet) *
Protected in daily life activities, bathing, accidental splashes, short swimming, car washing, parachuting, hang gliding and skiing – it is resistant to perspiration, water vapor, rain drops.
Tested for water resistance up to 5 ATM corresponding to 50 meters
WATER RESISTANT 100M – (10 ATM / 300 Feet) *
Protected in daily life activities, swimming, snorkeling, mountain climbing, parachuting, hang gliding, skiing and all kinds of sports challenges
Tested for water resistance up to 10 ATM corresponding to 100 m
WATER RESISTANT 200M – (20 ATM / 660 Feet) *
Protected in daily life activities, free diving without scuba gear, and all kinds of water sports.
Tested for water resistance up to 20 ATM corresponding to 200 m
WATER RESISTANT 300M – (30 ATM / 1000 Feet) *
Protected for scuba diving to a depth of 30 meters, for 2 hours.
Tested for water resistance up to 30 ATM corresponding to 300 m
WATER RESISTANT 500M – (50 ATM / 1650 Feet) *
Protected for scuba diving to a depth of 50 meters, for 2 hours.
Tested for water resistance up to 50 ATM corresponding to 500 m
* The meter values do 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)
Testings
We recommend testing water resistance annually by an authorized retailer or service center, 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 if the inside of the glass becomes fogged up and does not clear within a day, or sea water enters the watch, immediately bring 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.
- If you want to go 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.
Diving Watch
The unidirectional turning bezel on your ZENO Diving-Watch, with its precision ratchet, is for the measurement of dive time. The shape of the bezel is designed for easy hand rotation, even with diving gloves. For safety, the bezel can only turn counterclockwise. If it is accidentally moved it will indicate a longer elapsed dive time. At the start of a dive, turn the bezel so that the zero mark is in front of the minute-hand. The minute hand will always show the number of minutes that have elapsed since the dive started.
The solid construction and the protection system of the diving watch guarantee maximum reliability. To ensure water-resistance, we recommend that the watch is checked once a year by you ZENO retailer. Clean the watch regularly with lukewarm soapy water. This cleaning is especially recommended after contact with sea water.
