Buying tips
- 01IWC Pilot watches suit padded leather or canvas straps best — matching the aviation heritage.
- 02The Portugieser is a dress watch — slim, un-padded leather that tapers to 16mm looks most correct.
- 03The Big Pilot at 46mm and 22mm needs a substantial strap — thin leather will look wrong.
- 04The Aquatimer takes rubber or sailcloth — it's a diver and deserves a sport strap.
