Shining in Summer Blue

Performed via a crown with two positions (for winding and time-setting), manual winding works in both directions: clockwise for the chronograph, counterclockwise for the watch. 25 turns of the crown are enough to obtain a 100% charge of the chronograph barrel. A star-shaped open worked oscillating weight handles one-way automatic winding of the watch function. Framed by a 44 mm case available in various materials, the closed or open worked dial of the Defy El Primero 21 features an inner bezel bearing a scale graduated from 1 to 100 around which a 1/100th of a second hand sweeps at lightning speed of one turn per second.

What makes the Defy El Primero 21 so innovative (and alluring) is the technology is integral to the futuristic look of the watch. Take for example the Defy El Primero 21 Blue with a titanium strap. The cutaway dial has a crisp, industrial design which showcases the fact that the watch chronograph escapement is wholly separate from the timekeeping one.

This marvellous mechanism is housed in a 44 mm case made of grade 5 titanium and has three, high-tech strap options: black rubber bonded with blue alligator leather; blue rubber; or ultralight titanium. These bracelets are all outfitted with a titanium double folding clasp.
