Self-winding chronograph

Regatta function (continued)

For a yacht race, the chronograph should be started at the warning signal by pressing pusher A. Once the 5 circles on the display have changed colour to blue, this means that 5 minutes have passed since the warning signal. Once the circles have changed to red, this means that 10 minutes have elapsed and that the starting line can be crossed.

NOTE: If the chronograph function is stopped, the regatta function also stops, since the two functions are synchro- nised.

Apnea function (cal. 3601)

Pusher A: start – stop, start – stop etc. Timing to 1/8th of a second.

Pusher B: reset (after a stop).

Apnea function based on a 14 minute dive:

In addition to the hours and minutes hands, this movement has an indi- cator that displays the elapsed time of a dive. This indicator operates simultaneously with the chronograph seconds hand. Each circle on the display corresponds to 1 minute.

Before a dive, the chronograph should be started. Once the 7 circles on the display have changed to red, this means that 7 minutes have elapsed. Once the red colour has disappeared from the 7 circles this means that 7 more minutes have elapsed.

The Omega SA 1400 is recognized for its automatic movement that embodies reliability and robustness. This model features a classic design bolstered by a stainless steel case, ensuring durability while maintaining a sophisticated appearance. The 1400 utilizes an intricate balance wheel, which enhances its accuracy and provides a power reserve that withstands the test of time.

The Omega SA 1530, meanwhile, is a standout for its pioneering co-axial escapement technology. This innovative mechanism, developed by George Daniels in the 1970s, offers greater precision and stability, as well as reduced friction between the moving parts.

This model is equipped with anti-magnetic technology, protecting its inner mechanisms from electromagnetic fields, thus ensuring its continued accuracy in everyday life.

The Omega SA 1424 is particularly notable for its bold design and robust construction. It is often viewed as a new generation of dive watches, equipped with luminous markers for visibility in low-light conditions. The water resistance of the 1424 ensures it can withstand the rigors of underwater exploration, making it an ideal companion for adventure enthusiasts.

Lastly, the Omega SA 2520 model stands out with its sophisticated chronograph function. This timepiece is optimized for precision timing with additional features such as a tachymetric scale, allowing users to measure speed over distances. The 2520 boasts a dynamic design, often adorned with a striking bezel and a combination of polished and brushed finishes, ensuring it remains a statement piece on any wrist.
