What makes a Good Dive Watch | Beginner’s guide 2021

Dive watches have surpassed standard timepieces in the modern era due to their luxurious, smart features.

Over time, watch companies have developed low-cost diver’s watches.

There is no doubt that a dive watch can catch anyone’s attention, but shopping relying on its appearance is a fool’s game.

Before you get it, you should be aware of some essential info. Otherwise, I am confident that you will be puzzled and select the wrong one after seeing so many gleaming watches. And it won’t go away for two months. 

I answered it in such a simple way that it will only take 5 minutes to read, and then you will be able to get the reliable dive watch of your choice at a reasonable price.

What Makes A Good Dive Watch- Beginner Guide’s


You’ve seen a watch face, but in a diver watch, the timepiece contains many more essential features than regular watches.

So you must know all details advantages of belonging and be able to purchase a fantastic watch.


It is obvious a dive watch should have protection from water and water pressure. Ultimate a watch also be a gadget, so it has to protect from seawater. The part of water resistance is crucial itself.

Water-resistance measures by Meters or feet. Suppose a watch claimed ” water resistance 100m or 330 feet,” then it implies you can go up to that particular point wear the watch.

The higher the water resistance value, the deeper you can go. Water resistance is basically a certificate of protection for you and your watch.

For example, you wear a watch with a water resistance rating of 200 m. It means you can go about 200 meters deep, and your watch will be fine, as well as able to withstand the water pressure.

In most scenarios, professional divers go very deep, require more than 300 m water-resistance watches.

However, if you only enjoy sea-levels sports, such as scuba diving, snorkelling, and surfing. You can go to a minimum level of the sea by simply using water resistance between 100 and 200 m.

3. Crystal

After water resistance, crystal is another crucial point to check. The crystal means the face glass of a dive watch. It is necessary because you have to see the time, depth, how much you spend time in the deep sea or how long you can stay more.

The crystal material is mainly made of three different materials: acrylic glass, minerals, and synthetic Sapphire. Each material has pros and cons.

Acrylic glass or crystal is cheap and can withstand breakage very well. But the disadvantage is Acrylic glass easily scratches though the scratches are gone quickly by polishing agents.

Minerals or hardened minerals are more water-resistant and scratch-proof than acrylic glass.

Sapphire is expensive and more scratchproof but not strong as hardened crystal.

Many companies mixture sapphire and hardened glass to enhance legibility, scratch-proof, resistance against water. But a little expensive.

NOTE- Hardlex is a kind of crystal mineral made by Seiko, so the crystal glass comes cheap and maintains the quality.

4. Bezel

You’ve probably heard the term “bezel” before. In a diver watch, the Bezel is very important.

The Bezel is usually a round-shaped ring that sticks out from the watch crystal and contains some marks. It rotates either clockwise or anticlockwise.

The role of a Bezel is to calculate the elapsed time. The ‘zero’ marks align with a minute hand, so one diver can easily access it by seeing the minute hand.

The Bezel is sometimes in different colors for better legibility. Bezel act as a stopwatch or reminder for divers.

Rotating Bezel may be unidirectional, bidirectional, stationary, Tachymeter. A unidirectional bezel is the best for divers because it rotates one way, counterclockwise. Hence the error is minimized.

5. Luminous/ Legibility

Everything you packed and went to the deep dark sea, how the hell you can see the dial at the dark.


Luminous work there as an angel. You can see the dial so crystal and clear.

Lumens are inbuilt in the dial marks, watch hands, and bezels (zero) marks. In the dark, it glows like an angel.

Luminous like- Radium based, Tritium based, and Photoluminescent.

Radium is no longer uses because of health sake. 

Most use Lume is Photoluminescent which is common and does not react as radioactive elements.

Illuminated screens are used on digital diving watches to improve visibility in low-light conditions.

6. Display

The display comes either analog or Digital.

Analog or Digital both have advantages and disadvantages. But maximum divers like Analog dial. 

An analog dial looks much beautiful and standard than digital.

Other hands Digital direct show the number of time which found quick read than analog.

Picking a display is complete to you.

I always prefer an analog one, which will you like, Analog or Display?

7. Marks and Crown

Marks help a lot to watch time, notably Bezel Marks.

Crown- The crown and crown material has to be water-resistant. This is the way water can goes to watch.  Crown set for the time and wind the movement. Crowns are two types push/pull and screw down.

Which one is good for you to know all facts 

The push/ pull crown Screw-down crown
The push/ pull crown can bear up to 200 m or more securely. They are great at water resistance than screw down. The push/ pull crown can bear up to 1000 m or more securely. They are great at water resistance than screw down.
The advantage of push/pull crown is- more secure, more water resistance, one push-pull set, you can manually set anytime. Advantages– waterproof, cannot open accidentally, For secure crown screw down for a set time. 
Disadvantages– The biggest drawback of push/pull is if you forget to push after pull then jump into the water, water easily enters the watch. Disadvantage- you can’t operate it underwater.

In my opinion, nobody operates anything underwater if you want a watch for regular or casual looking push/to pull crown best for you. Accessible to one push set.

Those all features are present in the watch dial.

Now move to the material.

Material is a key point cause material is one thing that ensures the watch from the galvanic corrosiveness of seawater.


1. Watchcase Material

The watch case has to withstand water pressure. Therefore the casings are usually composed of austenitic stainless steels, including grade 316L or 904L.

In addition, steel alloy pitting with high resistance like- ceramics, synthetic resin, titanium, and plastics. 

Stainless steel is more prominent because of its 

  • Cheap
  • Lightweight
  • more water resistance
  • unbreakable
  • rustproof

2. Band Material ( Watch strap/Bracelet)

If the band is made of metal, then the material should appear the same as watchcase material. Suppose our band is metal-based and watch case stainless steel, then the band material has stainless steel.

In this way, able to endure the galvanic corrosiveness of seawater.

Most watch straps are made of polyurethane, rubber, silicone, etc. Titanium metal band or mesh bracelet of sufficient length to make it easier to wear your watch on a sleeve.

Metal watch strap- more common and look expensive glossy, and shiny. Leather straps have many advantages. The leather and its soft, comfy feel make it a great choice to wear all day long also. Nato – Nato becomes more popular day by day after Omegas are worn on James Bond’s wrist.
Mainly stainless steel use as metal in a watch band.
Leather band lighter than metal straps
The advantage deployment clasp doubles security lock system;

It ultimately protects the watch from falling.
Advantage– soft
Best for daily wear
· The watch won’t fall off since the spring bars and the watch itself are linked together.
· A wide variety of color selections are extremely inexpensive prices point.
Metal straps are heavier than other materials. The negative point of the leather band is- 
· too expensive, 
· leather will deteriorate over time
· wrinkle appear after excessive wear 
· You may take care of leather
Due to their dirt, moisture, and odor absorption, they will need to be washed on a frequent basis if worn every day.

Rubber-Rubber straps are most typically seen on watches that are known for their durability, including Casio G-Shocks.

Thump up- 

  • Best choice for everyday wear
  • A rubber strap is handy and less absorb moisture and dirt
  • You can roughly use it in wet condition
  • Down side- Though rubber bracelets are cheap yet over time, they can smell bad. You can feel sweaty in a hot climate.

Which band material you go for will depend on what you use the watch for.

3. Bezel Material

Bezel usually rotating either clockwise or counterclockwise. The bezel material  Metals were the only material utilized for the bezel for several years.

Followed by Aluminium and ceramic have become widely famous materials in many aspects of watchmaking.

Stainless steel is more dependable for its longevity and strength. Stainless steel can protect from rust.

The negative point of stainless steel is weighty and discolor than other materials.

Aluminum is exceptionally lightweight and cost-effective. The down point of aluminum is less durable.

In today’s watchmaking industry, Ceramic bezels are becoming increasingly widespread. Ceramic is less scratch resistance and more expensive than the other two.


Watch movements implies the power source of the watch that keeps moving and showing the correct time.

Watch movement is another crucial thing to be careful about before choosing a timepiece.

Watch movements mainly three ways Quartz, Mechanical, and Automatic.

Quartz  Automatic Mechanical
It ultimately depends on battery power.  Energy comes from the wearer’s wrist 100 small springs and parts
Energy comes from the hand-winding
· accurate time
· low maintenance
· Quartz can last up to 5 years
· Lightweight
· Less expensive
· No need for Battery
· Self-winding
· Regular wear
it can go a lifetime.
· No battery headache
· Aesthetics and fascinating looks.
When you review any dive watch, it claims either swiss quartz or Japanese quartz. Automatic watches are thicker than quartz Where the quartz hand rotates like tick tick, the mechanical timepiece rotates smooth butter.
In Japanese movements, negligible errors occur
Swiss assemble by hand made.
A rotor is present power metric by a mainspring wound either manually or by a self-winding
Japanese movements provide lower-priced luxury, swiss maintains higher quality; Japanese and Swiss automatic movementJapanese and Swiss movements ( hand-winding)

1.Quartz – 

When you review any dive watch, it claims either swiss quartz or Japanese quartz.

Japanese Quartz mainly focuses on functionality while swiss more focus on its appearance. Japanese quartz is less expensive than Swiss watch movements.

In Japanese movements, negligible errors occur as it assembles by robotics. Whereas swiss assemble by hand made.

Japanese movements provide lower-priced luxury, and another hand, swiss maintains higher quality; thus, it comes more costly than Japanese movement watches.

2.Automatic Movement

In the Automatic movement mechanism, the Automatic energy comes from the wearer’s wrist by creating a motion kinetic energy. Automatic watches are thicker than quartz or manual ones because of the rotor. And it is weighty.

A rotor is present within the parts. When the wearer move or the watch moves, the rotor moves and creates energy to the mainspring. As a result, the watch gives time.

Mechanical Movements:

In a mechanical watch, there are more than 100 small springs and parts built. Each has a significant role. Mechanical watches look slim and weighty.

Where the quartz hand rotates like tick tick, the mechanical timepiece rotates smooth butter.

A mechanical watch is a power metric by a mainspring, which must be wound either manually or by a self-winding mechanism regularly.


Every Diving watch has an elapsed time checker that is Rotating Bezel. A rotating bezel acts as a stopwatch or reminder watch.

Before diving into the water, the bezel point zero aligns with the minute hand. This way, divers maintain their time in the water.

The bezel of diving watches is “unidirectional. A Rachet present for turn into counterclockwise. Some timepiece contains chronograph.


ISO- International Organization for Standardization. A diver watch standard regulates by ISO- 6425.

ISO 6425 stands for this particular watch how well it is sealed against water incursion or water resistance.

The water pressure measures the units such as bar, atmospheres, meters, and feet.


  • Watch case standard size- 40- 42 mm
  • The best size for small wrist- 36-39 mm
  • For medium- 40 to 44 mm
  • Large size- Above 46 mm


It is so essential after purchasing any timepiece; you need some care of them. Every watch is made with some precise things. 

Here are few tips for Easy to Maintain Dive watch

1. Polish the crystal

2. Check the crown

3. Clean the Bezel, checks time to time its rotating movements

4. Take care of the watch case by watch polishing kit.

5. Wash the watch bracelet after all-day wear.

6. Service every 3 years if needed 2 years.


Everyone has different preferences and needs. What about you?

If you want to buy a watch for regular wear, then you have to look at these five features – 1. Water resistance, 2. Movements, 3. Watch materials, 4. Crystal legibility, 5. Brands.

You can check this is best for regular wear.

You want to buy for deep diving; then you have to look at ISO Certified, Bezel, Legibility and buy a little expensive.

It’s like these watches are very useful.
