The Iconic Pilot: A Watch Test of the IWC Mark XX
ArticleHands-on reviewDec 2025Ruediger Bucher
Very positiveRecommends
A thorough WatchTime test calling the Mark XX perhaps the best Mark yet. It praises the refined dial, ideal 40mm size, long power reserve and strong value against the Big Pilot 43, but notes a rickety strap mechanism, a timing outlier and excessive resemblance to the Big Pilot.

What the review says, point by point
- Dialpositive

- The looseness is not noticeable when the watch is worn.
- Movementmixed
- Sees the much longer power reserve as the new calibre's greatest advantage over the ETA-based predecessor.
