The IWC IW31712-15 is a limited edition of 100 piecs created in honor of the Milan IWC Boutique. It marks a return of the Split Seconds Portugieser – a watch that was last seen in the collection around 2006. The IW371215 features a red gold case and a blue dial with tachymeter and telemeter scales, not unlike the 2004 Barozzi IW3712-12. The caseback is engraved with 01/100 and the Milanese ‘Biscione’.
