Take control of time with the Time Since Launch Clock. This single-use device allows you to mark the start of your epoch. Additionally, the long-scale Time Since Launch clock can count up to 2,738 years. Simply pull the pin to mark the beginning of any occasion, like your wedding day or the birth of your baby. The Time Since Launch clock comes with two LCDs, displaying seconds, minutes, hours and days since launch. Designed to live much longer than you, the clock comes in a durable borosilicate glass tube. Likewise, gasketed aluminum caps are used to seal both ends. Intended to celebrate the presence instead of the past, the clock is a continuous reminder of our brief existence. When you are ready, just pull the stainless steel launch pin to start the timer.
