IWC reference IW329703 is the Big Pilot’s Watch 43 Edition “MR PORTER EDITION 1,” a bronze-cased collaboration with MR PORTER. It pairs a black dial and gold-plated hands with IWC-manufactured automatic caliber 82100, a 60-hour power reserve and an annual production limit of 500 pieces.
What is the IWC Big Pilot 43 MR PORTER Edition?
IW329703 is the exact reference for IWC’s Big Pilot’s Watch 43 Edition “MR PORTER EDITION 1.” IWC identifies it as a collaboration with MR PORTER, rather than a standard Big Pilot 43 or another bronze IWC model. The manufacturer’s official product page lists it as a past-collection watch.
The design combines a bronze case and crown with a black dial, gold-plated hands and a black Alcantara strap. IWC specifies a 43 mm case diameter and a 14.4 mm case height. The watch has a screwed-in crown and convex sapphire glass with antireflective coating on both sides.

Why do listed case-height figures differ?
IWC’s product page gives the case height as 14.4 mm. MR PORTER’s surfaced US product listing gives 13.6 mm. The two listings therefore disagree; IWC’s manufacturer figure is the more appropriate specification to use, while the retailer’s number should not be silently combined with it.
How many IW329703 watches were made?
IWC states an annual production limit of 500 pieces on its official product page. That is a limit per year, not a confirmed total number sold, currently available, or still in circulation. The page does not establish how many examples were ultimately produced.

What strap fits IWC IW329703?
IWC specifies a 21 mm strap width and an EasX-CHANGE system for the supplied black Alcantara strap. The listed buckle width is 18 mm. While these figures help identify replacement options, width alone does not confirm that a third-party strap will attach correctly: check that the strap is explicitly compatible with the watch’s EasX-CHANGE interface before ordering.
