Chopard Happy Hearts

In 1957, Omega introduced model series designed to reflect the needs of specific professions. The Speedmaster with a chronograph and tachymeter scale, later known as the Moonwatch. The Railmaster, the Bienne company's answer to the anti-magnetic Rolex Milgauss (reference 6451), designed for power plant and nuclear research workers. And finally, the Seamaster 300 for divers. However, the very first Seamaster saw the light of day much earlier, in 1948.
