This pre-owned IWC Pilot's Watch Chronograph Top Gun IW389101 marks a landmark moment in IWC's watchmaking: the first application of the acclaimed in-house Calibre 69380 flyback chronograph to the iconic ceramic Top Gun Chronograph. Introduced at Watches & Wonders 2022, the IW389101 brought genuine manufacture movement credentials to what had previously relied on a modified base calibre — making it a significantly more compelling proposition for the serious enthusiast.

The 44.5mm black ceramic case provides exceptional scratch resistance and a commanding, purposeful aesthetic rooted in military aviation heritage. The flyback function allows the chronograph to be reset and immediately restarted in a single action — genuine pilot functionality. Presented in good condition with original box and documentation (warranty card dated May 2022).

Ceramic Case Care

Black zirconia ceramic is one of the hardest materials used in watchmaking — virtually immune to everyday scratches from keys, coins, and hard surfaces. However, ceramic is brittle and can chip or crack when struck sharply by hard edges. Take particular care near hard work surfaces. The black colour runs consistently through the ceramic, meaning minor chips will appear as fractures rather than revealing a contrasting colour underneath.

Textile Strap Maintenance

The technical textile strap can be cleaned with a damp cloth and mild soap, then allowed to air-dry thoroughly. IWC's quick-change strap system requires no tools — simply slide and click to fit alternative straps. A wide range of replacement options in rubber, leather, and textile materials is available from IWC boutiques and authorised retailers, allowing you to easily change the watch's character.

Service Recommendations

IWC recommends a full service every 5 years under normal conditions. Calibre 69380 is an in-house movement and should be serviced by IWC's authorised network or a specialist watchmaker experienced with IWC movements. The flyback mechanism requires careful attention during any service — always use a qualified specialist. Budget approximately £600–£900 for an authorised service.

Magnetic Protection

The IW389101 features an inner soft-iron cage providing strong protection against magnetic fields — a genuine engineering benefit derived from aviation requirements. This protection is entirely passive and requires no maintenance, but be aware that extremely powerful magnets (industrial- or medical-grade) can still affect movement over time.

The 44.5mm case suits wrist circumferences from approximately 16.5cm to 21cm (6.5 to 8.3 inches). The black ceramic case and matching textile strap create a visually unified, purposeful look that sits proportionally on medium to large wrists. IWC's quick-change strap system allows tool-free swapping, making it simple to experiment with different strap options without visiting a watchmaker.
