The Electricianz Hybrid E-Code is part of the brand's Hybrid Mechanical Time Display. It is a stunning dual core machine with a self-winding automatic movement and a state-of-the-art electronic in-house module, which consists of a PCB (Printed Circuit Board) powered by a lithium battery. The result is a unique product experience with a stunning night vision of the hours, minutes and retrograde seconds function. The 5 seconds function is activated by the push button at 9 o'clock and flashes for 5 seconds before returning to its initial position with a luminous retrograde movement. Every Hybrid watch comes with 10 LEDs - 5 for chasing the darkness and 5 for having fun with the illuminated retrograde seconds function. For an experience on your wrist that's unique to the market, look no further!
