Your average no compromise space watch

Of course, there’s nothing average about the Space Discovery. It is an instrument that redefines what a watch can and should do in space. We are very proud of it. In fact, we wouldn’t wish your average astronaut to wear anything less.

The Halda Concept

The Space Discovery marks the inception of the Halda concept with interchangeable units for different purposes. It consists of one time platform and two time modules. Each module provides optimum performance in its respective environment. On earth for the Mechanical Module, in space for the Space Module.

The journey: developing a watch for space

You can only do so much testing on earth. Sooner or later you have to try it out in its designa­ted environment. A space mission is the result of many years in planning and preparation. From the moment of lift-off, time is the most precious commodity and every single second is a vital measurement used to its fullest. The only time the astronaut is not working is when he or she is asleep, providing the Halda prototype countless opportunities to show its worth.

So, when the crew of STS-128 returned to earth, we were eager to evaluate the data and feedback. The prototype had performed better than expected. It accurately counted MET, kept the different earth times, measured G-Forces and counted particles. The Halda prototype was a gem to have in space. We also received invaluable feedback on a few key areas we could improve upon. From lift-off to touch down, the following improvements have been made as a direct result of the mission.


The Flight Strap; material upgrade.

We have improved the flight strap to make it even stronger, and also added material to the inside of the strap to make it more comfortable to wear.

The Display; enhanced legibility.

We fine tuned the wavelengths of the colour of the light in the display. This might seem like a minor detail, but in reality it greatly improved the usability of the watch.

Docking Mechaninsm; upgrade to Triple Security.

Now the Space Module locks to the Time Platform by using a three step process. This is more or less the same system that astronauts use when locking their helmets to the space suits before working in space. When “engaged” the module is safe. When “locked”, the triple-safety docking-system eliminates any risk of the Space Module accidently coming loose.

Shuttle
Halda Watch Co. Where space is an in-house speciality.

The various functions that truly make the Space Module an astronaut’s instrument have been researched and developed in-house by the Halda team.

Inside the TECAMAX™ case, cutting edge technology is driven by a low power consumption microprocessor for ultimate efficiency. This better serves both the LCD display and LED backlight as well as the specific space functions: the G-Force sensor and the Particle Counter.

Safety First: fool proofing your next space trip.

It is mandatory to change the glass of the Space Module from the earth standard sapphire chrystal to the space standard Hesalite Crystal when going to space. The reason for this is safety. The way other crystals normaly used in watches can shatter when broken can become a hazard in space. Changing to Hesalite Crystal takes care of this problem, and of course this is a service we provide free of charge.

The Halda Space Discovery comes with what we call The Flight Strap, a velcro strap made to secure the Space Discovery to your arm when a metal link is undesirable. It is designed to meet the toughest requirements. Each Flight Strap comes individually numbered, just as the watch itself.

Bezel

The part of a watch most exposed to external stress is the bezel, the ring that protects the case and the sapphire crystal. Therefore we equipped the Space module with a bezel made of the best suiting material given its purpose – 316L-steel. This type of steel is a material that does not break or shatter – clear advantages for space use.

Triple Safety
Backlight

The backlight

Extensive research has been made in order to optimize the wavelengths of the colour of the backlight, which is controlled by an automatic light sensor. The backlight adapts to the surrounding light to deliver optimum legibility in all situations.

A new material

The case of the Space Module is made of TECAMAX™, a material developed for military and space use. It is certified by NASA and meets the toughest requirements of durability and precision. TECAMAX™ is extraordinarily light with outstanding isolation capabilities and strength, such as enduring high temperatures and exposure to acid and chemicals.

A new material

The G-force sensor

The integrated 3-axis accelerometer measures G-forces in three dimensions. This gives the astronaut access to critical information during key times of the Space Mission, such as take-off and landing. Max recorded G-forces are stored for evaluation.

Earth Time

In orbit you cover a lot of ground fast – in 24 h you go around the world 16 times. This is why we have developed The Earth Time function. It allows for easy access to local time and time zones of 192 countries on earth. In addition to this, the Space Module display shows Dual Times (two world times shown simultaneously) and full calendar functions, a chronograph and splits down to 1/10 s. Add to that Mission Elapsed Time (MET), Countdown, MET and UTC Alarm, 24 h timer and an Event log and you are ready to go.

Timekeeping and split time presented down to an accuracy of 1/10th second.

Timer

24-hour timer.

Alarm set relative to MET (Mission Elapsed Time).

Event Log

Logging function for various events. For each event the date, UTC-time, and a serial number is stored. Log up to 99 events.

Reveille

An alarm clock adjustable to sound either once at set time or same time every day, or only on weekdays.

Countdown

A countdown to a certain point in time/a certain day. Shows number of days, hours, minutes and seconds remaining until selected time.

Mission Time

Countdown for lift off can be set for a precise time. At the set time, the watch automatically begins measuring acceleration during lift off, displaying current G-forces as they occur. Once acceleration stops, the function automatically displays Mission Elapsed Time (MET). This function is based on the NASA Countdown 101 protocol, the official framework for space shuttle lift-off. It is also prepared to accommodate the countdown protocol for the new generation of Are rockets.

Earth Time

Earth Time lets you know what the time is in various parts of the world. Here you will find all the countries of the world, see their local time and their time zone.

G-Force

Acceleration, the G-force, can be measured automatically during liftoff, during the re-entry phase, or be initiated at a chosen point in time. During measurement, the highest G-force value is stored in a separate memory.
