Time Since Launch
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.
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.
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.
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.

I picked up a TSL to mark the "launch" of our baby and couldn't be happier with the experience. Not only is it a unique and special heirloom that I can pass down to my daughter someday i.e. "this clock was right there at the hospital when you were born", but it has also turned out to be unexpectedly handy for checking the status on those newborn milestones at a glance since it is not uncommon as new parents to be so tired that we don't know what day it is, let alone how many have passed! Highly recommended. :)
I loved the concept ever since I discovered this product years ago. I haven't had a life event momentous enough to warrant one of these until now (still a few months from my launch date). The item comes in what I can only describe as appropriate packaging that is entirely in keeping with the character of the brand. It adequately protects the item within and is of high quality without feeling extraneous and wasteful; a hard line to walk. The product itself is simple but has a solidity that (surprisingly) makes the high price understandable. I thought I was initially paying mostly for the concept, but this is a solid piece of kit. I have no reason to doubt that this was genuinely designed with longevity in mind. Overall, this is an item that is more than the sum of its parts and exactly as advertised.
I love how it looks!
Very nice design and it feels well made. Even the packaging is super minimalistic, clean and eco friendly - I just love it. It’s a gift for my brother’s wedding and I’m pretty sure they will love it as well.
Just incredibly innovative. Very emotive product and everything is thought of! Fascinating way to capture time. Highly recommend.
Time Since We Met
I love it. I got this retro-futuristic industrial-looking elegant timepiece to mark the meeting with this handsome French man I had matched with on my first day on a dating app driven by my desire for our relationship to last at least till the batteries die 40+ years into the future, right? and I gave it to him so that no matter what, he will always remember this trip he took from Bordeaux to Madrid to meet me as soon as the borders opened on this covid year. It was so thrilling to pull the trigger together. About the device: First of, the packaging. It is a solid, reliable, and environmentally concerned simple cardboard box, but more importantly, it gives you the feeling of getting something really serious, like a secret weapon, which in the end it is what I’m using it for... The directions inside the box, so cute and well explained. The font you use is so perfect. I am keeping it myself –along with the ring that triggers the timer. It looks so mysterious. Love it. Then the device itself!! it is larger than I imagined. An object you want to take in your hands, feel its weight, swing it, turn it around and stare at the little LCDs of this awesome timepiece to count the days passed... to remember the beginning of something remarkable. Whatever ends up happening in this relationship, I am confident I bought the most romantic device and will have him remembering the day we first met, our first dance, our first kiss. Thank you, CW&T sooooo much for creating this gem. I feel so honored to finally have one of your timepieces, yay!!!!
