Cal. 9051 movement uses anti-magnetic materials for the balance spring and surrounding components to boost the overall magnetic resistance of the watch. This new Promaster Auto Diver is capable of maintaining performance even when placed 1 centimeter from a device emitting a magnetic field of 16,000 A/m. The watch is also resistant to magnetic fields from everyday devices, including smartphones, and it can even be used aboard ships with magnetic compasses. In addition to magnetic resistance, the watch also has ISO compliant*2 water resistance up to 200 meters. It can run for 42 hours when fully wound, with daily accuracy of -10 to +20 seconds – solid performance for a mechanical watch. The hour hand, minute hand, and indexes have a luminescent coating to ensure high visibility.The bold trapezoid indentations around the edge of the case are both stylish and functional, providing a rugged look and a sure grip when using the bezel. The case has a two-piece structure and uses Super Titanium™ with CITIZEN’s proprietary surface-hardening technology, Duratect*3, making the watch incredibly light for its size. The rugged and tough good looks of this model are enhanced by an intricate almost stud-like pyramid pattern on the bezel and the dial with shades that shift depending on the viewing angle.

Water Resistance

Defining Water Resistance in Terms of Smartwatches and Connected Watches

Various terms are used for expressing water resistance performance. If you want to be able to easily compare watches, you need to understand these terms first.

Commonly used units of measurement include "m (meters)," "bar/atm (atmospheres)," "WATER RESISTANT/W.R.," and "Daily Water Resistance". We're going to explain in detail the level of water resistance required in the performance of daily activities.

Take a look at the following table of regular wristwatches to easily understand how water resistance is defined.

Name Specifications Indication Description Features
Dial or Case back Mark
Non-water resistant watches Watches that don't have WATER RESIST(ANT) engraved on their case back should not be put in direct contact with water.
Everyday-use water resistant watch Water resistance of 3bar WATER RESIST(ANT) Water resistance of 3bar Can withstand perspiration, drops of water when washing the face, rainfall, and other sources of moisture found in everyday life. Cannot be used under conditions involving huge changes in water pressure. Not designed for working with water or diving, but enough for providing water resistance for daily activities.
Upgraded everyday-use water resistant watch Water resistance of 5bar WATER
W.R.5BAR Water resistance of 5bar Recommended for people who often come into contact with water such as those whose job involves water and those who participate in water sports; however, it cannot be used for skin diving. Provides a higher level of water resistance than water resistance for everyday-use.
Water resistance of 10bar WATER
W.R.10BAR Water resistance of 10bar A wristwatch that can be safely used by people who often come into contact with water such as those whose job involves water (fishing and agriculture industry, car washing, restaurants, etc.) and those who participate in skin diving and other water sports (swimming, yachting, sport fishing, etc.).
Button operations not possible when covered in drops of water.
Comes with a screw-down crown or a double-gasket crown.
Water resistance of 20bar WATER RESIST
W.R.20BAR Water resistance of 20bar
Water-resistant watches for diving Water resistance of 200m WATER RESIST
Water resistance of 200m Can withstand pressure to a water depth of 200m to 300m and extended immersions in water. Can be used for skin diving, scuba diving, and the like;
however, it cannot be used for saturation diving.
Comes with a mechanism for measuring dive time and decompression stops (except digital watches).
Water resistance of 300m WATER RESIST
Water resistance of 300m
Water-resistant watches for saturation diving Water resistance of 300m PROFESSIONAL
Water resistance of 300m Can withstand pressure to a water depth of 300m and comes with a helium release valve. Comes with a unidirectional rotating bezel for measuring dive time and decompression stops
Water resistance of 800m PROFESSIONAL
Water resistance of 800m Can withstand pressure to a water depth of 800m and comes with a helium release valve. Comes with a unidirectional rotating bezel for measuring dive time and decompression stops.
Water resistance of 1,000m PROFESSIONAL
Water resistance of 1,000m Can withstand pressure to a water depth of 1,000m and comes with a helium release valve. Comes with a unidirectional rotating bezel for measuring dive time and decompression stops.

Four Types of Water-Resistant Wristwatches

Four Types of Water-Resistant Wristwatches

Many people want a water-resistant wristwatch, but the level of water resistance required varies from person to person. This includes those who simply worry about sudden rain showers, those who need to wear a wristwatch while doing work involving water such as washing cars or dishes, and those who wish to wear a wristwatch while swimming, skin diving, scuba diving, or other forms of water and marine sports. Here we introduce water resistance functions in various scenarios.

  1. 1Water resistance for daily use against rain, perspiration, etc.

    While situations in which we get soaked with water are rare, people will find a wristwatch with a water resistance of 3bar sufficient if they are simply worried about the effects of rainwater or perspiration. Watches with this setting are not suitable for work involving water or swimming, but their level of water resistance is just enough for performing daily activities. They will be fine if you happen to splash a little water on them while washing your hands whenever you get home, or if you get them a little wet in light rain showers.

    A water resistance of 3bar is the minimal level required to proceed with daily activities. On the other hand, it is best to remove your watch if you wish to enjoy water sports or expect to get wet in water rides and attractions at amusement parks and the like.

  2. 2Water resistance against splashes

    A water resistance of 5bar or more will ensure that the watch remains safe even if you participate in water sports or other activities where you can get splashed with water. Wristwatches with this setting can be used not only for sports and recreation, but also for work that requires frequent contact with water. Although they have a higher level of water resistance than those designed for everyday use, 5bar is still not enough for skin diving.

  3. 3Water resistance for water sports and fishing

    Wristwatches with a water resistance of 10bar to 20bar or more can be safely used in the fishing, agriculture, and car washing industries, and when doing water sports such as swimming, fishing, yachting, surfing, and motorboating. They can also be used for skin diving.

    However, button operations are often not possible when water drops have adhered to the watch. People who wish to fully use their smartwatch or connected watch while doing water sports must take particular care. If you wish to listen to music while swimming, then you need to check whether the watch you want has that function before buying it.

    Although watches with a water resistance of 10bar are basically considered as suitable for swimming, this usually only applies to careful entry into swimming pools and swimming. Many people enjoy diving when swimming, but water may seep inside the watch if they do so because more water pressure is applied to the wristwatch when diving. Seeping may occur not only when diving, but also when doing other intense activities, so care must be taken.

  4. 4Complete water resistance

    Watches with water resistance for skin diving and saturation diving are completely safe to use in all situations involving water.

    Water-resistant models for diving (water resistance of 200m to 300m) are recommended when scuba diving. Except for the digital models, these wristwatches are equipped with a mechanism for measuring dive time and decompression stops.

    Water-resistant models for saturation diving (water resistance of 300m to 1,000m) can withstand pressure to a water depth of 300m to 1,000m and comes with a helium release valve.
