Time Since Launch

Time Since Launch


It's time to launch your personal epoch.

Time Since Launch is a single-use, long-scale launch clock.

Pull the pin to begin counting for 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, two LCDs show days, hours, minutes and seconds since launch. This timepiece is built to count for 2,738 years.

Elevate an otherwise arbitrary moment to super awesome status.

Minimal Time Since Launch wall mount. Made of bent aluminum with a glass bead finish.

Available for purchase with your Time Since Launch or here.

1962. Mercury Atlas 6. John Glenn. A stopwatch. A shared global timezone.

When John Glenn became the first American astronaut to orbit earth, the only piece of technology on his body, other than a spacesuit, was a 12-hour stopwatch. Soon after launch, Glenn started his stopwatch in sync with tracking stations across the world. At that moment, Mission Elapsed Time (MET) began counting up from zero. A launch timer was not only required for a successful mission (ie. to calculate position), it also created a shared global timezone.

Quietly situated at the center of a tremendous collaborative feat of human innovation, the launch clock marks an arbitrary Moment Zero. A moment shared by humans scattered all over the world and one hurling through space.
What's your moment zero? 

Time Since Launch ships with its LCDs in pre-launch mode, this rhythmic cycling through each of the segments ensures even wear and tear.

To launch, pull the stainless-steel launch pin to initiate the timer.

You can only do this once!

This action burns that instant 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.

Electronics specified for longevity and low power consumption. Time Since Launch consists of only essential electrical components to mitigate potential failure points. Mounted on a matte black PCB with gold plated traces, Time Since Launch has 2 chips, a few passive electronic components (resistors, diodes and capacitors), two 6-digit LCDs and batteries. That’s it.

It draws less than 6uA (microamps) of current running at 3.3 volts. This gives us an energy usage of about 20 microwatts (millionths of a watt). 

A 20+ year battery life. 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 20+ year battery life estimate, we take Energizer’s stated capacity of 3,500mAh and round down to 3,000mAh (to be conservative), divide by 6uA and then take off another 30% (to account for external factors). This gives us an conservative estimated run time of 40 years.

A real time chip with ±2ppm accuracy. To keep time, Time Since Launch uses an Epson RX8900 chip. This real-time clock chip with a temperature-compensated crystal oscillator is extremely stable at room temperature. It can hold its frequency at less than ±2 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 ±2ppm accuracy, you’d miss by less than 10 inches.

Safely change batteries without losing time. 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.

During COVID: Launch your own calendar - New Years in August

This is such a profoundly understated and elegant concept design. Since hearing about the item, and discussing with some friends (one of whom had must moved to the area from New York), we decided it was time for a Skype- virtual New Years Eve party, right in the middle of August, 2020. Summers are generally full of fun, vacation time with friends and yes the 4th of July and accompanying fireworks is rivaled only by New Years Eve, at least here in the states. So, given the respectful social distancing and safety precautions my friends and colleagues have taken, a virtual mew years party in August was just what we needed. This incredible device was the catalyst, and it did not disappoint. We already have one scheduled for next August, just for fun. Side note: I had the virtual gathering scheduled for 2 hours, yet friends were so happy to reconnect over a celebratory event, it went over three hours. In short, incredible tool and I highly recommend it. -CTC

Great build quality and all that. But the best thing is that the clock makes me look for special moments in everyday life. Waiting for the right time to pull the pin and start the timer. Thought about it yesterday when my youngest of three went to the toilet for the first time by himself. Or should I wait until I marry their mother? It's a great piece of art this timer!

Very thoughtful design

It's clear the Che-Wei and Taylor thought through every detail of the design, all the way down to the packaging. Respect.

Well packaged and fast!

Haven’t opened it up yet as it is all part of an anniversary present! The products are well secured and came in quickly!

The perfect gift

I bought this amazing item for the 26th birthday of my boyfriend and it was the perfect gift: original, beautiful, (very) long lasting... He loves it!
