The main materials of the solid Omega Speedmaster replica watches are stainless steel. Their Cal. 3603 are the first movements that are carried with co-axial escapements. The co-axial system can be called an important turning point in history of Omega brand. This innovative technique is invented by George Daniel who has a close relationship with Omega.
In 2005, Cal. 3603 adopted a new co-axial technique to reduce the friction between components. This innovative design can ensure the durability and precision of the calibre. And the Swiss movements can support GMT functions. The 44.25mm round cases are solid enough to provide a full protection to the excellent movements. Their hour markers and hands are all made of steel . And the central GMT hand has a red tip with white luminescence. There are three sub-dials used for chronograph functions.
There are some red elements on the silver dial. These red details are obvious to add extra energetic feelings. Besides, Omega copy watches with Swiss mechanical movements have witnessed the return of classical design elements which are the iconic “broad arrow” hands. The remarkable Omega timepieces are worth collecting.
