ALL FERMI ON SALE NOW! The first sale of its kind in Reactor history. We are overstocked, so now is your chance to own a great, versatile timepiece at an unbelievable price. Fermi is Reactor's tribute to fine Italian design, and bears the name of the Father of the nuclear reactor. It's a classic design in a modern 45mm size, made so easy-wearing by its 12mm slim profile. Equipped with a Swiss quartz movement, it is as precise and accurate as its namesake, and the 200M depth rating and Reactor DNA means Fermi is ready for anything.

Since our founding in 2003, Reactor has endeavored to push the limits of sport watch design. We believe we have reached a new pinnacle with Poseidon Titanium. A natural extension of the highly successful stainless model, Poseidon Ti offers all the same toughness with a 40% reduction in weight, absolute resistance to corrosion from salt water and Never Dark^® technology in every model. Taking it even further, the limited edition model features a first for Reactor - a true mechanical automatic movement. While normally too fragile for our standards, Poseidon Ti Limited is fitted with the newest mechanical movement from Japan, the incredible Miyota 9015 - the first mechanical movement to withstand our testing and remain highly accurate. Also available in a quartz model with 10-year power cell.
