Throughout history, men and women have set their sights on exploring the highest peaks, the deepest valleys and any part of the world not yet before ventured.
When doing any type of exploring, a person must be prepared. One detail that isn’t overlooked by explorers is the usefulness of a wristwatch.
A watch can not only do simple things — like telling the time or the date — but can also be the difference between death and survival, being remembered as a pioneer or just as one who succumbed to the conditions.

Historically, Rolex was the go-to watch for explorers. Rolex was the brand on the wrists of Sir Edmund Hillary when he became the first man to stand atop Mount Everest in 1953.
When Reinhold Messner climbed the summit without oxygen in 1970, he too was wearing a Rolex. Robin Knox-Johnston traveled around the globe nonstop in 1969 wearing a Rolex, as did Ranulph Fiennes.
In New York City, the Explorers Club celebrates everything having to do with exploration and its members include the likes of Buzz Aldrin, Will Steger and Sylvia Earle. Rolex underwrites the club, which helps plan expeditions to all corners of the world. If an expedition is approved, Rolex will loan watches to the individuals to wear during the adventure.
Rolex watches aren’t the only ones on the wrists of explorers.

The Omega Speedmaster famously had helped the Apollo 13 astronauts safely make their way back to Earth by using the watch to time 14-second course corrections.
The Omega watches continued to work correctly after being in space and in the cold capsule after it lost power.

In 2012, Austrian skydiver Felix Baumgartner broke the speed of sound after free falling from 120,100 feet during a televised event.
On his wrist while he was falling back to Earth after being at an altitude with a brisk -65 degree Celsius forecast was a steel-cased Zenith El Primero Stratos Flyback Striking 10th. The watch became the first to break the speed of sound after the nine-minute descent.

Can a watch save your life? For one hunter in Alaska, it certainly helped. Hunting in Alaska, Mark Spencer became stranded along the mighty Susitna River. He was able to activate a frequency on his aptly named Brietling Emergency. The frequency transmits on the aircraft emergency channel, which led to rescuers finding his exact location.

Another interesting blog post thanks. I would add Eterna and Thor Heyerdahl. I had an Eterna Kontiki 20 for a while.

Something not quite right here.
To fall 120100 feet (22.7 miles) in nine minutes, means you will reach the terminal velocity of 122 mph.
No skydiver could travel at the speed of sound (Around 700 mph) and survive.

And yet, he did. The incredibly thin atmosphere allowed him to exceed terminal velocity and break the sound barrier. See https://www.guinnessworldrecords.com/records/hall-of-fame/felix-baumgartner-first-person-to-break-sound-barrier-in-freefall

Well Felix Baumgartner did exactly as stated. What you fail to forget when you state that the terminal velocity (TV) is around 122 mph is the density of the air at an altitude of 120,000 feet. At sea level the density of air numerically is 23.77 and indeed the TV is about 120 mph. I won’t state the units on density since they likely would not be understood. The density of air at 120,000 is on the order of 0.04. That is about 600 times “thinner” than air at sea level and thus the drag, especially when the release was initiated, was very low. Gravity changes as well, but not as much.
NASA has a nice online calculator at https://www.grc.nasa.gov/WWW/K-12/airplane/termv.html. It is limited to a maximum altitude of 100000 feet but will give you an idea how the variables such as drag, gravity, etc. interact and make Felix’s record possible.

Great story I never gave it a thought. Thank you.

Thanks Mark. Another interesting story that I had not thought about before

One watch that has a rich history, is seldom mentioned, the Glycine Airman. It was very popular with Pilots and air crew during the Vietnam war, even more popular than the GMT. It was the perfect watch for Pilots because it was a true 24 hour watch. Zulu time could be set on the face of the watch was linked to the calender, Zulu time was a different day in Vietnam, and local time could be set on the outer locking bezel. Unlike the GMT, the bezel could be securely locked. The hacking mechanism precisely stopped the second hand at 12, no fumbling around, just pull the crown and a small wire popped up stopping the second hand at exactly 12. The movement was a 25 jewel self winding adjusted for position, extremely accurate. Durable? I am still wearing mine 61 years later.
