Time Since Launch

Time Since Launch is a single-use, long-scale launch clock.
Pull the pin to begin counting for 1 million days, or over 2,738 years.
Use this very long-scale timepiece to mark the beginning of your epoch. It could begin when you get married, have a baby, quit smoking, launch a rocket, or on an ordinary Tuesday morning.
Your epoch is safeguarded within this unique timepiece designed and over-engineered to outlive you.
Suspended in a durable borosilicate glass tube and sealed with gasketed aluminum end-caps, the display shows days, hours, minutes and seconds since launch.
Wall mount for Time Since Launch made of bent aluminum with a glass bead finish.
Available for purchase with your Time Since Launch or here.
Customize your Time Since Launch with same-day laser marked engraving.
Time Since Launch ships in pre-launch mode. This rhythmic cycling through each display segment ensures even wear and tear up until launch time.
Pull the pin to initiate the timer.
NOTE : You can only do this once!
Pulling the pin burns your launch time into the chip's silicon, making that moment yours forever.
Time Since Launch is off the grid, both in terms of power and its ability to keep accurate time. Unlike your phone, it doesn’t rely on a surprisingly fragile external multi-billion dollar timing and power infrastructure.
Made with precision machined metals, over-engineered and over-specified electronics, Time Since Launch will outlive you. This assembly of parts - from physical materials to electronic components - were selected with longevity in mind.
If anything ever happens to your Time Since Launch, as long as the chip is physically intact, you can recover your Moment Zero and transplant it into a surrogate.
Time Since Launch is made from machined aluminum endcaps and a durable borosilicate tube. The electronics are suspended and deliberately made visible. The enclosure is easy to take apart. If ever something breaks, you can easily identify what went wrong so it can be fixed.
Time Since Launch consists of only essential electrical components to mitigate potential failure points. Mounted on a matte black VT-447 PCB with gold plated traces, Time Since Launch has 2 chips, a few diodes and capacitors, a custom 12 digit LCD, batteries and 2 LEDs for launch time. That’s it.
It draws less than 2uA (microamps) of current running at 3.3 volts. This gives us an energy usage of about 6.6 microwatts (millionths of a watt).
Yes, you read that right. 150 years. Version 2 of Time Since Launch ships with 2 x AA Energizer L91 Ultimate Lithium batteries. These batteries have a capacity of 3,500mAh, and a 20 year shelf life, which means they are guaranteed to have 95% of their original capacity after 20 years of sitting on a shelf.
To arrive at our 150+ year battery life estimate, we take Energizer’s stated capacity of 3,500mAh and round down to 3,000mAh (to be conservative), divide by 2uA and then take off another 10% (to account for external factors). This gives us an conservative estimated run time of 150 years.
To keep time, Time Since Launch uses a low power real time clock chip with a temperature-compensated crystal oscillator that is extremely stable at room temperature. It can hold its frequency at less than ±2.5 parts per million (ppm). This level of accuracy is 10x better than a normal wristwatch crystal which, with an accuracy of ±20ppm.
If you were to shoot a basketball from a court in NYC to a hoop in Philly with ±2.5ppm accuracy, you’d miss by one foot.
About 6 months before it is time to change the batteries, the display indicates your batteries are low. During the swap, backup capacitors keep the real time chip powered and running without losing time.
To change the batteries, pull the aluminum caps out of the glass tube to expose the battery holders. Pull out your old batteries and put in new ones.

We purchased this for our wedding day and had the counter started on "NOW pronounce you married". It's something we love looking back to to see how long we've been married and we plan to use it as a time marker in photos moving forward. Seems incredibly sturdy, but we'll see in 100 years...
High quality and great gift that amazes people when you help them remember a special day!
J’ai acheté cette objet pour notre pacs avec mon compagnon et on l’adore. Le symbole de cette objet est fort, nous en sommes extrêmement reconnaissants
Perfect Wedding gift from the "Techie" Father
My wife, who officiated my daughter's wedding, incorporated the Time Since Launch into the ceremony. The groom held it while my daughter pulled the pin marking their own epoch together. Another memorable moment on the this wonderful day.
We had a family member pull this during our first kiss at our wedding and it was such a cool thing to have that we can look at every day!
