Waterproof Antimagnetic
Waterproofing
Please check the water resistance rating on the watch face or case back and use the watch correctly within its specified range.
Water resistance is guaranteed through various factory inspections at the time of shipment. Water resistance may deteriorate depending on usage conditions.
We recommend regular inspections.
- Watches with everyday water resistance (3 bar) can be used during activities like washing your face, but they cannot be used in environments where they might be submerged in water.
- Watches rated for enhanced water resistance for daily use (5 bar) can be used for swimming, but they cannot be used for any type of diving, including skin diving.
- Watches rated for enhanced water resistance for daily use (10/20 bar) can be used for skin diving (free diving). However, they cannot be used for scuba diving with air tanks or saturation diving using helium gas.

- ：Watches with WATER RESIST (ANT) or W.R. marked on the case back, and watches with 3BAR (3ATM, 30m) marked alongside the above
- ：Watches with a case back marked “WATER RESIST (ANT)” or “W.R.” along with a 5BAR (5ATM, 50m) rating
- ：Watches with a case back marked WATER RESIST (ANT) or W.R. and displaying either 10BAR (10ATM, 100m) or 20BAR (20ATM, 200m)
Caution
- Always use the crown in the pushed-in position (normal position). If the crown is screw-lock type, ensure it is securely tightened.
- Do not operate the crown or buttons while underwater or when wet. Moisture may enter the watch interior, causing water resistance failure.
- For non-waterproof watches, avoid temporary exposure to water droplets (splashes from washing your face, rain, etc.) and sweat. If the watch gets wet from water or sweat, wipe off the moisture with a dry, soft cloth.
- Even for watches rated for everyday water resistance, avoid direct exposure to strong water pressure, such as from a running faucet. Water pressure exceeding the limit may cause water resistance failure.
- For watches rated for enhanced everyday water resistance, after exposure to seawater, thoroughly rinse any seawater from the case. After rinsing, wipe it dry to prevent rust or other issues.
- Due to the nature of leather straps, exposure to water may affect durability and cause issues like discoloration or adhesive failure. When using the watch in water, replace the strap with one made of another material (metal or rubber) beforehand.
- Some moisture may be present inside the watch. When the outside air temperature is lower than the temperature inside the watch, the glass surface may fog up. If the fogging is temporary, there is no internal damage. However, if it persists for a long time or if moisture has entered the watch interior, do not leave it as is. Contact the store where you purchased it or the Orient Product Service Center.
Magnetic Resistance Performance
AQ (Analog Quartz) Watches
AQ watches utilize the force of a step motor (rotational force from an ultra-small magnet) to move the hour, minute, and second hands.
Therefore, if the watch is brought near magnetic products or electrical appliances that generate strong magnetic fields, it may temporarily stop, lose time, or gain time. However, moving it away from the magnetic source will restore its accuracy and normal operation.
This occurs because the rotation of the step motor is temporarily disrupted by the influence of strong external magnetic fields.
Mechanical (Hand-Wound, Automatic) Watches
While not as pronounced as with AQ watches, mechanical watches can be affected by magnetism, causing them to temporarily stop, lose time, or gain time.
This occurs because the escapement's movement is temporarily disrupted by strong external magnetic fields.
Furthermore, prolonged proximity to strong magnetic products or electrical appliances can magnetize movement components. Even after removal from the magnetic field, this magnetization may adversely affect subsequent accuracy. In such cases, demagnetizing the affected parts will restore the watch's precision.
About Magnetic-Resistant Watches
A magnetic-resistant watch is a timepiece with enhanced resistance to magnetic fields.
Magnetic Resistance Properties and Types
| Type | Magnetic Field Strength Tolerance (For DC Magnetic Fields※1) |
Description |
|---|---|---|
| Standard Watches | 1,600 A/m(20 Gauss) ※2 |
Minimum magnetic resistance performance required for wristwatches (ISO Standard) |
| A type of magnetic-resistant clock※4 | 4,800 A/m(60 Gauss) ※2 |
A level where performance is maintained in most cases even when the anti-magnetic watch is placed within 5 cm of devices generating magnetic fields in daily life |
| Diver's Watch※3 | 4,800 A/m(60 Gauss) ※2 |
Magnetic resistance performance divers' watches must meet (ISO standard) |
- ：Direct Current Magnetic Field (DC): Magnetic fields emitted by permanent magnets or electromagnets powered by direct current sources such as dry cell batteries.
Alternating Current Magnetic Field (AC): Magnetic fields emitted by alternating current power sources. These have a greater impact on watches than direct current magnetic fields. - ：A/m (ampere per meter) is the unit (SI system) used to express magnetic field strength.
While gauss is a well-known unit used for magnetism, it is a unit (CGS system) that expresses magnetic flux density. - : Diver's watches (waterproof watches for diving) possess the same level of magnetic resistance as Type I anti-magnetic watches.
- : Mechanical watches possess Type I anti-magnetic performance. This is not specifically stated on the product.
