IWC Portuguese 3718

The Portuguese Chronograph reference 3718 represents IWC's chronograph offering within the Portuguese collection, distinguished by its white gold case construction and silver dial configuration. This reference positions itself as a precious metal variant within the chronograph series. The 40.9mm case is crafted from 18k white gold with a fixed bezel design. A sapphire crystal protects the silver dial, while the automatic movement provides the timekeeping mechanism. Water resistance extends to 30 meters, suitable for basic daily wear protection. This reference appeals to collectors seeking a luxury metal chronograph with restrained dial aesthetics. The white gold case material and moderate sizing make it suitable for formal occasions, while the automatic movement eliminates the need for battery replacement. The silver dial provides clear legibility against the precious metal case.
