In 1970, Hamilton announced the "Hamilton Pulsar," which revolutionized the way time was displayed on watches. And 50 years later, the "Hamilton PSR" was born. It celebrates the birth of the world's first LED digital watch. A hybrid display and stainless steel case bring this innovative timepiece back to the present. The design is based on the "P2" released in 1973, and reproduces the iconic wide cushion-shaped case. The size is also the same as the original, 40.8mm x 34.7mm. While the crystal has been updated from ruby to sapphire crystal, it has the same three-dimensional form as the original model, giving it a retro-future feeling. The LCD display allows for constant illumination, and by combining it with organic EL, the red 7-segment LED lights up by operating the button on the right side of the case.
