After updating the Portugieser Chronograph with a new in-house movement in early 2015 (you can read our article here), IWC is presenting its iconic chronograph on a stainless steel bracelet for the first time.
Thanks to the new bracelet option, this elegant and sporty chronograph becomes even more versatile. The surface of the H-shaped bracelet is beautifully polished and satin-finished. The butterfly-shaped folding clasp enhances wearing comfort.
The new model with stainless steel bracelet (ref. IW371617) has a stainless steel case, a silver-plated dial and blue hands and appliques.
The sapphire crystal caseback reveals the self-winding in-house chronograph movement 69355, with a frequency of 4 Hz (28,800 vibrations per hour) and a power reserve of 46 hours.
