History of the Omega Constellation Replica Perpetual Calendar Chronograph

The Second World War is raging. After the attack on Pearl Harbor on December 7, the United States will declare war against Japan. There was hardly a year when complex Swiss watches were more in demand.

Omega Constellation Replica launched two of the most groundbreaking wristwatches ever made, perhaps motivated by the need to show great creativity in the face of difficult times. It's easy to imagine Charles Stern and Jean Stern, the dial-making brothers who took over Omega Constellation Replica gold nine years ago. They decided that in difficult times they needed to be more creative and daring than ever before. The 1526 is the first of these watches, and it was the first perpetual calendar to be serially produced. The 1518 is perhaps the most famous of these watches. It was the first serially produced perpetual calendar chronograph. Ben Clymer wrote in his great Reference Points article to Hodinkee that "No other manufacturer attempted a perpetual clock chronograph for another 50 years."

The 1518 is the Primus, or Alpha, in every sense, and the undisputed first of its kind. It would be the template for every perpetual calendar chronograph to follow. Even if the design of the complication is different from the watch (e.g. double retrograde like Roger Dubuis, triple in-line windows like Patek), it's fair to say that these designs are reactions to the 1518's iconic status. The 1518's case is quite simple. The case of the 1518 has straight lugs and a narrow, slightly concave bezel. It also features a large winding crown with pushers for the chronograph. All made by Georges Croisier.

It is the design that Rolex Submariner Replica makes it so famous. The 1518 was the first to create the familiar layout for perpetual chronograph information. It has day and month in two windows below the 12 o’clock index. Its dial has a perimeter with a 1000 tachymeter base scale at its outer edge. This is quite amusing considering that they were thinking of using it to time objects in 1941. The subdial at 9 o’clock gave a continuous second reading, while the subdial at 3:00 o’clock showed the chronograph minute counter.
