IWC Reference 3714

Ø 40.9 mm, 3 bar, Sapphire Glass, Alligator leather/Stainless steel C L A S S I C TI M E P I ECE , NEWLY INTERPRETED
You might refer to this chronograph from the Portugieser (Portuguese) family as the big brother of Reference 3714: it has a slightly larger diameter and is 2 millimetres higher, although the latter is barely noticeable due to the arched-edge front glass. This traditional type of watch glass lends the design a classic equilibrium, which is further emphasized by the railway-trackstyle chapter ring central to the appearance of the original Portugieser. The Portugieser Chronograph Classic is equipped with the IWC-manufactured 89361 calibre. This movement was designed specifically to record stop times up to 12 hours on a separate subdial, where they can be read off as simply as the time of day. The Reference 3904 is available in 18-carat red gold or stainless steel. Both models have a silver-plated or slate-coloured dial. The rotor, decorated with Geneva stripes, can be viewed through the transparent sapphire-glass back. All models are supplied with a Santoni alligator leather strap.
