Why do dive watches have a bezel?
Necessity being the mother of invention, the rotating dive watch bezel was introduced by Rolex and Blancpain in the early 1950’s to track a diver’s bottom time, or time spent underwater. Oxygen being limited, the bezel can act as a reminder to prevent divers from exceeding their diving time limit.
What is the 12 o’clock bezel on a watch for?
Its function is actually quite simple: before a diver’s descent, the 12 o’clock bezel marker is aligned with the minute hand, allowing the elapsed time, up to 60 minutes, to be read on the bezel (which is why quite a few dive watches come with a particularly prominent minute hand).
When do you align the bezel on a diving helmet?

Which way does a dive watch bezel turn?
As the evaluation of the remaining air in your cylinder is based on the information of the elapsed time of the dive, the rotating bezel for a diver's watch is designed to rotate only counterclockwise, so that the watch is prevented from displaying the elapsed time shorter than it actually is.
How does a diving watch work?
Dive watches come equipped with a rotating bezel that lets the wearer know how long they have been underwater. In some models, it will also show the diver's depth. Most dive watches have rubber or stainless steel straps. They are the most adaptable to seawater and can withstand pressure, direct sunlight, and humidity.
Why do dive watches have rotating bezels?
What Is A Bezel For On A Diver's Watch? The purpose of a rotating bezel is to warn divers when their oxygen is running low. As most scuba tanks run out of oxygen in around 60 minutes, rotating bezels are split into 60 sections with each section representing one minute.
How does a rotating bezel work?
With a unidirectional bezel, you simply spin the bezel counterclockwise until the zero marker (unusually an inverted triangle) is aligned with the minute hand. As time passes, the minute hand will move around the dial and you simply read the amount of elapsed time against the 60-minute scale on the bezel.

What is a dive watch bezel?
Dive watch bezels are simply used to measure elapsed time; however, knowing how much time has passed allows divers to figure out a number of other important things, such as whether or not a decompression stop is needed.
What is a rotating bezel on a GMT watch?
On the majority of GMT watches, there is a rotating bezel engraved with a 24-hour scale that works in conjunction with an additional hour hand to keep track of an additional time zone. As useful as those are, it is perhaps the rotating timing bezels found on dive watches that are the most important.
How to track safety stop on dive watch?
Should a safety stop be needed on the ascent, the rotating timing bezel on dive watches can be used to track the duration of the stop itself. For example, if after spending a period of time at depth, a diver requires a safety stop of 5 minutes, they can simply ascent to the proper depth (measured with a depth gauge), and then align the bezel on their dive watch with the minute hand to track how long they have spent at the stop. Modern dive computers will do all of this automatically; however, having a reliable backup method that does not rely on batteries can be the difference between life and death in certain situations.
Why do dive watches have rotating bezels?

How a watch bezel works
A watch bezel includes a sexagesimal scale, and its functionality is not anything different from a standard timer. When diving, please align the minute hand to the zero markers engraved on the bezel.

How to protect the time on a dive watch?
In the late ‘60s, several watch companies decided that the best way to protect the timing bezel was to move it under the crystal. This not only kept it from getting knocked, it also put the elapsed time markings closer to the dial and hands. To control the ring, an extra crown was needed and one of the iconic forms of dive watch was born—the twin-crown diver, a style that has remained to this day in watches like Alpina’s Seastrong Heritage or the Longines Legend Diver. The twin-crown design is an attractive one but not the most ergonomic for real world use since it requires twisting a tiny crown, often with gloves on.
What are bezels made of?
The earliest ones were simple printed aluminum rings, pressure-fitted in place. Some were made from Bakelite, an early form of plastic that was susceptible to cracking, while others, like the Doxa’s, were made from tough, engraved steel. The weakness of all of these materials is in their susceptibility to fading and scratching, so in the past decade, brands have come up with new materials from which to craft their bezels. Sapphire came first, followed by ceramic, both virtually scratch- and fade-proof. Omega, meanwhile, has made use of a proprietary material called LiquidMetal that has all the advantages of ceramic but allows for more flexibility in color and appearance.
How does the Hublot Oceanographic work?
The Hublot Oceanographic is a technological tour de force with a central minute counter chronograph, massive titanium case and 1,000 meters of water-resistance . The bold timing ring sits under the sapphire crystal and is controlled by a crown at 10:00 that locks in place with precision cut meshed teeth and capped with a hinged lever. While well protected, it also presents a challenge for the diver when it comes time to operate it, perhaps a case in point of the best solution being left to the simplest one.
Which way does the inner ring of a watch rotate?
This outer grippy ring is linked to the inner rotating scale by a geared clutch mechanism on the left flank of the watch.

Is Blancpain a unidirectional bezel?
Blancpain was the first company to make its timing bezel unidirectional, only ratcheting counter-clockwise. A unidirectional bezel is useful since, should it get bumped during the rough and tumble of diving, it will only subtract time from a diver’s bottom time and not put him in danger of overstaying his no-deco limit. Until Blancpain’s patent ran out on this feature, other brands had to make do with bezels that spun both ways. Today, unidirectional bezels are virtually universal.

How to count up dive watch?
A dive watch bezel is typically the "count-up" type, meaning there are marks at 5- or 10-minute intervals ascending clockwise, and a "pip" or marker to indicate zero, which is typically aligned with 12 o'clock on the watch when the bezel is not in use. If, say, you enter the water and then reach deepest part of your descent at 12:30, you would simply align the pip, or zero mark, at 12:30 on your watch. This way, as the bottom time ticks by, you have a running gauge of how much has elapsed. (At 12:40, for example, the time will be aligned with the "10" marker on your bezel, meaning you've been on the bottom for 10 minutes.) Easy enough.
