What "Fake Top Gun Mission 45.5" Means
A fake Top Gun Mission 45.5 is a first copy of the IWC Pilot's Watch Chronograph Top Gun family built with a 45.5 mm case. "Mission 45.5" is not an IWC model name. It is shop slang used by replica sellers and collectors to describe the 45.5 mm black pilot chronograph, the size most buyers picture when they ask for a Top Gun. When the phrase shows up in a listing, you are looking at a first copy watch, not a genuine IWC, and it must never be sold or worn as one.
Two parts of the build decide what a Mission 45.5 is actually worth: the case and the movement. A ceramic or ceramic-coated case and an automatic Asian chronograph calibre drive the price far more than the dial, the hands, or the strap.
Before You Buy
- Identify the genuine reference you are comparing against, and note its stated case diameter.
- Have digital calipers and a small kitchen scale on hand.
- Set a budget tier, since the case material is the single largest cost driver.
- Accept that a first copy cannot be serviced by an authorised dealer and carries no factory warranty.
How to Evaluate a Rep Top Gun 45.5
- Measure the case across the widest point at 3 and 9 o'clock with calipers; a true 45.5 mm copy reads 45.2 to 45.8 mm, while anything under 44 mm is a different case size.
- Weigh the bare head. A ceramic or ceramic-coated build lands lighter than a solid steel case of the same diameter, and a heavy head is a hint of a plated steel shell.
- Study the case surface in daylight. Real black ceramic is matte with a faint grain; painted steel looks smooth and glossy, and chips at the lug edges expose grey metal.
- Read the dial print with a loupe. The brand line and the model text should be crisp, level, and evenly spaced, with no ink bleed into the black background.
- Check the subdial layout. Running seconds at 6 and a 12-hour totaliser at 12 match the standard Top Gun chronograph; a swapped layout points to a different movement inside.
- Run the chronograph five times. Press start, stop, and reset each round, and confirm the centre seconds hand returns to 12 with no drift.
- Inspect the date window at 3 o'clock. The number should sit flush with the dial and show no white plastic ring around the aperture.
- Charge the lume with a phone torch for 30 seconds, then check it in a dark room; a weak, fast-fading glow is the most common shortcut on budget copies.
- Work the crown and pushers. The crown should screw down smoothly and the pushers should return under spring pressure without wobble.
- Turn the watch over and read the caseback engraving. Sharp, deep lettering and a flat sapphire window are tier markers; shallow laser etching and mineral glass are not.
- Wear it for a week and log the daily rate against a phone clock before you commit to a second purchase from the same seller.
What Each Price Tier Gets You
Entry-level Mission 45.5 copies usually pair a plated steel case with a basic quartz or low-grade automatic movement. Mid-tier builds step up to a ceramic-coated case, sapphire crystal, and a decorated Asian chronograph. Top-tier builds use a full ceramic case, closer dial furniture, and a movement with a smoother chronograph action. Expect the gap between tiers to show most in the case finish and the reset feel of the chronograph, not in the box or the paperwork.
Red Flags in a Listing
- A claim that the watch is genuine, or that it comes with a valid manufacturer warranty.
- No stated case diameter, or a diameter that changes between photos.
- Stock catalogue images used in place of photos of the actual watch.
- A price far below the tier the seller claims, which usually means a plated case.
Care and Realistic Expectations
Keep a first copy away from hot water, steam, and chlorinated pools, even if the seller quotes a depth rating. Rinse the case with fresh water after contact with sweat or salt, and wipe the strap dry. Have any automatic movement serviced by an independent watchmaker when it starts losing more than 20 seconds a day, since a dealer will not touch it. Treat the watch as what it is: a look-alike built to a price, not an investment.
