Timekeeping: The Dive Watch, Deconstructed

It is ironic that  while watch companies are turning out more capable dive watches  helium release valves  absurd water resistance  innovative bezels  fewer and fewer SCUBA divers are wearing watches at all. Go on any dive boat and youre lucky to find one person wearing anything besides a dive computer on his wrist. The fact of the matter is  dive watches have become anachronistic novelties to all but a few old school divers who still rely on memory and math skills to calculate no-decompression limits. But dive watches are more popular than ever for even those who will never dip a toe in the ocean. Perhaps because of this surge in their popularity  combined with their lack of real world use  dive watches suffer from numerous misconceptions. People love to wear them but dont know a helium release valve from a no-deco limit. Were here to help. This article explains some of the basics of the dive watch  debunks some myths and sets things straight.

How Is a Dive Watch Used?

Even if you never plan to back roll into the Caribbean or explore a Great Lakes wreck  you should know how a diver uses a dive watch. For a diver  there are three primary pieces of data he needs to know at all times: his depth  his remaining air pressure and his bottom time. While all three can now be displayed on a modern digital dive computer  the traditional means is using gauges and a timepiece  the first two on analog brass and glass gauges attached to a regulator hose or strapped to a wrist and the latter via the dive watch. While the importance of remaining air pressure is easy to understand  depth and time are more theoretical and inextricably linked.

The deeper you dive  the more nitrogen from the compressed air you breathe is absorbed in your body tissue. As you ascend this nitrogen is released slowly but if you spend too long too deep  you have to stop on your way to the surface in order to decompress. Fail to decompress replica watches   or ascend too quickly and you risk getting the bends  which can be painful and even deadly. Scientists long ago devised tables that tell divers what the maximum times they can spend at each depth before they must decompress on their ascent. So knowing your depth and your time is vital.

In the early days of diving  the way to track dive time was to pull out the crown of your watch before descending  set the minute hand to twelve oclock  push in the crown and then start the dive. Of course  this was clumsy and always meant having to reset the time once back on the boat. The introduction of the rotating elapsed time bezel was a big leap forward. Contrary to some misconceptions  the bezel does not track the amount of air in the SCUBA tank. The bezel allows a diver to twist the bezel so that the arrow  or descent marker  aligns with the minute hand. As time passes  the minute hand is read against the bezel markings to quickly tell elapsed dive time. Knowing his depth and this time  along with the no-deco limit for his depth  a diver can safely carry out his dive.

Why Does the Bezel Only Turn One Way?

On early dive watches  the timing bezel turned both directions. But now  it is de rigueur for all dive watch bezels to only turn counter-clockwise. The reason for this is so that if the bezel is bumped accidentally during a dive  it will only move one direction  subtracting time from the dive and prompting the diver to end his dive early. If there was the possibility of extending a dive (as a bi-directional bezel could) a diver could be in danger of surpassing the no-deco limit.

Why Are the First 15 Minutes of a Bezel Marked Differently?

On many dive watch bezels  the first 15 or 20 minutes of markings are colored  yellow  orange  red  and have individual minute markers shown. This is again a remnant from past usage. Upon ascent  if a diver needs to time a shorter interval with more precision  most likely a decompression stop  it is helpful to be able to reset the zero marker to the minute hand and use the more finely marked area to track his time. Some dive watches  such as the military versions that Rolex and Omega built for the British Royal Navy  display minute markers on the full bezel.

How Deep is Deep Enough?

The first dive watches of the 1950s from Rolex  Blancpain  Omega and others had rather meager depth ratings by todays standards  about 100 meters. In the decades since  a sort of depth race began among watch companies and 1 000 meter depth ratings were seen on dive watches as early as the late 1960s. Today  there are some dive watches with ratings as deep as 12 000 meters. These ultra-deep divers appeal to watch fans for the same reason supercars with high top speeds appeal to car enthusiasts  displaying engineering prowess and ultimate performance. But for the vast majority of recreational or even professional divers  a 200 meter rated dive watch is more than enough. The International Standards Organization  or ISO  has a detailed standard for dive watches. The document specifies exactly how a dive watchs water resistance is to be tested and says that to be called a dive watch  a timepiece must have a minimum water resistance of 100 meters and have a method to track elapsed time (see above). And no  moving your arms underwater does not significantly increase water pressure on your watch.

How Does a Helium Release Valve Work?

One of the most misunderstood aspects of a dive watch is the helium release valve. Along with extraordinary depth ratings  many modern divers feature them yet most watch owners couldnt explain how they work. The fact of the matter is  for 99.9% of dive watch owners  the helium release valve is utterly useless. It was developed to solve a peculiar problem faced by a very small and elite group of divers.

Professional saturation divers are those who work at very deep depths for days on end. The air mixture that they breathe replaces nitrogen with helium  an inert gas that is harmless to breathe and doesnt cause the narcotic effect that nitrogen does at depth. In order to continue to work for long periods of time underwater  these divers live in a dry  pressurized chamber suspended from a ship or platform at the surface. They enter the water to work via an airlock and breathe the same pressure and mix of air as they do inside the chamber. When their work is done  the chamber is hoisted to the surface and pressure reduced gradually for days until the divers can emerge to surface air and pressure.

The problem with helium is  while it is safe to breathe  its molecules are very small. They can penetrate inside a dive watch while the diver is in the dry chamber between stints in the water. As the chamber is depressurized  the helium molecules expand inside the watch and look for any means to escape. The quickest route is usually by blowing the watch crystal off  an obvious hazard to both man and watch. So Rolex patented a one-way pressure relief valve that will pop open to allow helium to escape safely. The valve fake glashutte watch   some manually unscrewed  some automatic  can be found on many dive watches nowadays. If you think you will ever need this valve  chances are youre not reading this article right now.

Why Do Some Rubber Straps Look Like An Accordion?

Maybe youve noticed on many dive watches that the rubber straps have a section  typically near its attachment points on the watch case  which is rippled or vented. Contrary to some misconceptions  this is not to allow your wrist to breathe. Rather it allows the wearer to pull the strap tight over a wetsuit sleeve at the surface but remain tight as the diver descends. You see  neoprene wetsuits compress as water pressure increases. Even a strap that was tight at the surface will loosen up around this shrinking circumference causing the watch to flop around on the wrist. By pulling the vented strap tight at sea level  the vents will contract to take up the slack as the diver descends.

The Dive Watch is Dead. Long Live the Dive Watch.

Despite its absence from dive boats  the dive watch is alive and well  as a nod to history  an exercise in extreme engineering and a symbol of adventure. It is a talisman from days of exploration  when men descended into the sea for the first time to explore wrecks  discover reefs and do clandestine battle. And just as watch collectors are keepers of a tradition of a mechanical art  so too are dive watch owners keepers of a legacy of rugged instruments that accompanied man on some of his greatest adventures. Wear your dive watch proudly. And know how it works.

Design Spotlight LEAP

The living ecological alpine pod  or LEAP  wears its heart right on its name tag and provides all of the benefits of traditional mountain shelters  think trekking basecamps  not lavish homes  but with a significantly smaller environmental footprint. Much of the LEAPs green gains are derived from construction technologies for building planes and ships. Each LEAP is comprised of up to five modular living units  plus a biological toilet. The entrance units thermally isolated inner door  storage/drying rack replica watches   and rescue equipment hangar is optimized for the risks of high-alpine conditions. In terms of creature comforts  the refined living interior is fully customizable and includes a pantry  interior lighting  an electric induction cooker  adjustable bunks and optional panoramic windows. On the technology side  each LEAP can be outfitted with a variety of self-sufficient core systems to automatically diagnose structural issues fake graham watch   monitor weather conditions  maintain emergency communication channels and collect power via photovoltaic films on the exterior.

Once the appropriate prefabricated modules are selected  the entire shelter is assembled off-site and then flown to its desired mountain location via helicopter. In the event changes must be made to the basecamp  modules can be added with minimal crew support later on. At the end of the LEAPs useful lifespan  removing the structure is just as easy and leaves no lasting marks on the surrounding environment. While total cost hasnt been disclosed  the company has stated that these shelters will be highly competitive with the traditional solutions. We take that to mean expensive  but on par with what a horde of sherpas with engineering degrees and hammers might go for.

We’re not exactly sure how this happened, but alas, Victorinox Swiss Army released a glow-in-the-dark version of their most beloved Swiss Army Knife. While the color choice is one that would make grandpa roll over in his grave, it’s certain to be a hit among subcultures from coast to coast. For those of the hipster ilk, be sure to carry this folding apparatus right next to your guy-liner when attending a local Skrillex concert. But beware: hidden within the glowing object that you’re haphazardly twirling like a glow-stick is a sharp object that has been used by far greater men throughout history. If you can stand the name-calling and preconceived notions, this knife will still get the job done. We’re not saying we’d buy it, but we’re not saying we wouldn’t.
