What to know
The 2025 Endurance Pro IRONMAN World Championship edition uses grade-2 titanium for its 44mm case, reducing weight while retaining the Professional collection’s large, legible architecture. An anthracite dial is interrupted by blue and light-blue details, oversized luminous numerals, a pulsometer scale and the event emblem at six. A bidirectional compass bezel and blue rubber strap reinforce its role as a multisport instrument.

Breitling Calibre 82 is a thermocompensated SuperQuartz movement certified by COSC. It drives a 1/10-second chronograph, 30-minute counter and date display. The case is 12.5mm thick and water-resistant to 100 metres. Reference E823105A1M1S1 was introduced in August 2025 as a limited edition of 500 pieces.
