Is a 100m Water Resistant Watch Enough for Scuba Diving?

Is a 100m Water Resistant Watch Enough for Scuba Diving?

Are you confused about the depths you can dive with a 100-meter watch? Or maybe you’re just wondering if it’s safe to take your watch diving with you?

Well, you’ve come to the right place! In this blog, we’ll be diving into the depths of watch technology (no pun intended!) to explore the features and functions of a 100m watch and how it can be used for diving.

A 100-meter watch, also known as a water-resistant watch, is designed to withstand water pressure up to 100 meters. But just because a watch can withstand water pressure at a certain depth, does that mean it’s safe and suitable for diving?

In this blog, we’ll be separating fact from fiction, and diving into the nitty-gritty of what a 100m watch can and cannot do while diving. So, grab your dive gear, and let’s dive in!

Diving clock water and volatility

Improvement is usually indicated by the number of meters (fixed water column). Sometimes the implant is shown in turn or ATM (icon spare), which is equivalent to 10 times or 10 ATMs of a 100m fixed water column.

The higher the number of meters (or bar/ATM), the higher, the deep divers can be. If it just says ‘resistant to water, the clock is just spraying!

The resistance of the diving clock to water depends on the model and the price, but diving watches are usually resistant to a depth of at least 100 meters (according to ISO 6425).

This is fine for the single and the shallow. Today, most diving watches are resistant to water against 200 meters (20 times/ATMs).

Beule and Marker

One of the features of the classic diving watch is certainly its rotating ring. This ring is also known as a bezel. Almost all of them are analog dive watches.

The ring turns only on the left (sinewave) and graduates in minutes. Often the great units are 10, 20, 30, etc., large and/or different colors. In the dark, needles and time units also shine. Often a clear marker in 60 minutes (or zero line).

The marker keeps the water in the large needle of the time when entering the water. It can be read quickly and especially during diving how many days you are already diving. There are similar models in which diving time can be adjusted and read separately.

Other features of diving watches

A classic, uniform diving clock is heavier than a normal clock. This is because the external bezel must be made of high-pressure-resistant materials and seawater snacks. Titanium and stainless steel are the most commonly utilized materials. There are also diving watches made of artificial materials.

Clock strap is often made of rubber, polyurethane, or stainless steel. Remember that the belt is adjusted so that it can be put on the diving suit. Glass can be made of acrylic glass, mineral glasses, or sapphire crystals. The classic diving watches contain a threaded crown that allows (out of water) to set time and date through “screw up the crown”.

The other work of the nilogo diving clock

It is impossible to enumerate every possible use for the dive clock. The market is also more modern and the difference with diving computers is sometimes small. There are some functions that may be found in analog diving watches (digital joints).

  • Date and/or calendar
  • Chronometer: measure the passage time and on/off
  • Load mode: indicates that when the battery is required to load/replace
  • Water sensor: When the watch gets in contact with the water, the diving functions begin.
  • Diving Timeter: Possibly with an alarm function
  • Depth: diving and/or maximum diving depth measurement
  • Dumped Alarm: When the height is high, the alarm seems.

100m water resistant watch means

A watch that is rated as 100m water resistant means that it has been tested and certified to withstand water pressure at depths of up to 100 meters.

This rating is typically given to watches that are suitable for swimming and snorkeling, but not for diving.

It means that the watch can withstand accidental splashes of water or brief immersion in water, but should not be worn while diving or performing activities that would expose the watch to prolonged or heavy water contact.

Watch water resistance chart

Here is a general chart for watch water resistance ratings:

  • 30m (3 ATM or 3 bar): This rating means that the watch is splash-proof and can withstand accidental splashes of water, but should not be worn while swimming or showering.
  • 50m (5 ATM or 5 bar): This rating means that the watch is suitable for swimming and snorkeling, but not for diving.
  • 100m (10 ATM or 10 bar): This rating means that the watch is suitable for swimming, snorkeling, and water sports, but not for diving.
  • 200m (20 ATM or 20 bar): This rating means that the watch is suitable for diving in shallow waters.
  • 300m (30 ATM or 30 bar): This rating means that the watch is suitable for diving in deeper waters.
  • Professional dive watches: These watches are designed for deep sea diving and typically have a rating of at least 500m (50 ATM or 50 bar).

It’s worth noting that these ratings are not absolute, they are guidelines and the actual performance of a watch will depend on the construction, quality, and maintenance of the watch. It’s always recommended to consult the manufacturer’s instructions for more specific information about the watch’s water resistance.

Is 100m water resistant enough for diving

A 100m water resistance rating on a watch is not considered to be enough for diving.

While a watch with this rating can withstand water pressure at depths of up to 100 meters, it is not specifically designed for diving and may not have features such as a unidirectional bezel or a screw-down crown that are necessary for safe and accurate diving.

Additionally, the watch may not be able to withstand the pressure and conditions of deeper dives.

It is recommended to use a watch with a minimum rating of 200m (20 ATM or 20 bar) for diving in shallow waters and 300m (30 ATM or 30 bar) or higher for deeper dives.

Professional dive watches typically have a rating of at least 500m (50 ATM or 50 bar) and are specifically designed for deep sea diving.

It’s also worth noting that diving watches are tested to the ISO 6425 standard which is a more severe test than the regular resistance test and has more requirements for the watch to be considered suitable for diving.
