Breitling Watch Professional Endurance Pro Ironman X823109A1K1S1. Designed in partnership with the IRONMAN Group, luxury watch brand Breitling extend their ultimate athleisure collection of Endurance Pro watches to bring us the Breitling Professional Endurance Pro Ironman watch. Since its inception in 1978, the IRONMAN triathlon has represented the ultimate test of body, mind, and spirit for athletes. For Breitling, the three competition stages of swimming, cycling, and running are the same activities that feature prominently in the lifestyles of Breitling’s core customer base: men and women of action, purpose, and style. It is these very objective-driven individuals that require a wristwatch like the Endurance Pro Ironman. Measuring to 44mm in diameter, the Breitling Professional Endurance Pro Ironman watch is engineered entirely from Breitlight, an in-house material engineered by Breitling that is 3.3 times light than titanium and 5.8 times lighter than steel as well as being extremely durable, scratch resistant, anti-magnetic, anti-allergic and thermally stable. Topping the case is a bi-directional rotating bezel with engraved compass points and at 3 o’clock a non-screw locked crown delivers easy grip and a healthy water resistant rating of 100 metres. At the centre, the Breitling Endurance Pro Ironman opts for a deep red dial which fades out nicely to black as it reaches the inner bezel with pulsometer scale. To pair, the chronograph counters are dressed in black and detailed with red-accented hands. The hour and minutes hands are coated in Superluminova and the IRONMAN logo is included on the small seconds dial at 6 o’clock. Powering the design is the Breitling Caliber 82, a COSC-certified thermocompensated SuperQuartz movement which claims to be ten times more precise than regular quartz calibre.
