The Sea-Time Limited Edition uses
an ETA 2824-A2 automatic movement,
as you're probably aware.

The Yellow Dial version has a COSC
movement on the display case back.

COSC: Controle Officiel des Suisse Chronometre.
         
About Chronometers:

A chronometer is a high-precision watch capable of displaying the seconds and housing a movement that has been tested over several days, in different positions and at different temperatures, by an official neutral body (COSC).
Each chronometer is unique, identified by a number engraved on its movement and a certification number given by the COSC.
Each movement is individually tested for several consecutive days, in 5 positions and at 3 temperatures.
Each movement is individually measured. Any watch with the denomination "chronometer" is provided with a certified movement.         



            


The 2009 Sea Time Limited

However the main difference is
that the L.E. has blue screws.
Rather than the usual silver that are
commonly seen.

There is also a individual serial number
that's painted on the dial up to 100.
This is to indicate that 100 of this model
will be made.

Cheers,
Simon
