For the 3581.EY, Luminox adopts this spirit through the Navy SEAL mantra, “the only easy day was yesterday,” which stresses that every day you should work harder than the last, making the previous day seem easier. From strenuous conditioning on both land and in the sea to 4-hour sleep days, Navy SEALs are constantly pushed to their limits during training. With nearly 2/3 of the class quitting or “ringing the bell” due to pain or fatigue, only the toughest minds, bodies, and souls have what it takes to earn Navy SEAL status. The mantra is even prominently displayed on the dial, inspiring those who have it strapped to their wrist to dig deep and overcome any challenge in their way. Whether you’re training at the gym or on the job, you will be ready to push yourself to the limit.
