Historical significance
IWC Schaffhausen Pilot's Watch 44 mm Blue Quartz sits within IWC Schaffhausen's Pilot's Watch line, introduced in 1984. It carries the house codes established since 1868 — quartz tpt case, blue "grande tapisserie" dial and in-house automatic, superlative chronometer — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.
- Early production dials show a slightly different minute track, and collectors pay a premium for them.
- The case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.

Brand history
IWC Schaffhausen has spent more than 158 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Portugieser, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Florentine Ariosto Jones established IWC Schaffhausen in 1868, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every IWC Schaffhausen calibre produced today.
