IW3750-28Ref

The Da Vinci Perpetual Calendar reference IW3750-28 features a polished stainless steel case paired with a black dial. Debuting in 1985 with the reference 3570, this iconic perpetual calendar movement became a industry benchmark, eventually powering various IWC collections and models from JLC. The 39mm by 14.3mm timepiece includes hinged lugs and evolved through several movement iterations, starting with the caliber 7906(0).
