## FAQ
**Q1: What movement is inside the IW3902 Yacht Club Chronograph?**
A: The IW3902 series is powered by the IWC Caliber 79320 automatic chronograph movement, which is based on the ETA Valjoux 7750. This movement features a 44-hour power reserve and beats at 28,800 vph (4 Hz).
**Q2: After installation, the pusher feels tight or won‘t press. What should I do?**
A: This usually indicates the internal lever is misaligned or the pusher is screwed in too deep. Remove and check the movement side lever alignment. Also, verify the gasket thickness is not excessive. If unsure, consult a professional watchmaker.
**Q3: Do I need special tools to install this pusher?**
A: Yes. Pusher installation requires movement removal and specialized tools. Professional installation by a watchmaker is strongly recommended to avoid cross-threading or damaging the case.
**Q4: Why does my IW3902 have two pushers? Are they the same?**
A: The IW3902 features two pushers: the upper pusher (2 o‘clock) starts/stops the chronograph, and the lower pusher (4 o’clock) resets it. Both pushers are typically identical in size and design. This replacement pusher fits either position.
