Ref. IW375404
The IWC Schaffhausen Da Vinci Perpetual Rattrapante Rose Gold / Silver / French takes a 20 mm strap: measure between the lugs and that is the only number you need. We list 1,170 straps in that width. With a 41.5 mm case and 30 m of water resistance, a strap of medium thickness keeps the balance. Most straps here come with quick-release spring bars, so the swap takes a minute and no tool.
We do not sell watches. This page exists to find the straps that fit this one.
