1. Check the Movement Sweep

A genuine automatic movement produces a smooth, continuous sweep of the secondhand — the result of a balance wheel oscillating at 6-10 beats per second. Most counterfeits use cheap quartz movements that produce a distinct "tick-tick" stepping motion. Hold the watch steady and watch the secondhand: if it steps, it's not a genuine automatic. This single check eliminates the vast majority of fakes sold as automatic watches.

2. Feel the Weight

Genuine watches from established brands use quality materials — solid stainless steel cases, sapphire crystal, proper mechanical movements — all of which contribute to substantial weight. A genuine Tissot PRX weighs approximately 130g with bracelet; a counterfeit of the same watch often feels hollow or significantly lighter. Pick it up and compare against published specifications. If it feels surprisingly light, that's a warning sign.

3. Examine the Crown Resistance

On a genuine mechanical watch, the crown has distinct "click" positions for winding, neutral and setting. Winding the crown should produce felt resistance as the mainspring coils. On a counterfeit powered by a cheap quartz movement, the crown often turns loosely with no meaningful resistance, or produces uneven, gritty feedback. On screw-down crowns (common on dive watches), the threads should feel smooth and even — not rough or cross-threaded.

4. Inspect Dial Printing Quality

Under a loupe or even a magnifying app on your phone, examine the dial text, logo and indices. Genuine watches have crisp, even typography with no bleeding, uneven spacing or font inconsistencies. On counterfeits, logo lettering is often slightly blurred, applied indices are misaligned, or lume plots are inconsistently sized. The brand logo on genuine watches is a registered trademark and is applied with industrial precision — fakes frequently get this slightly wrong.

5. Verify the Caseback

Exhibition (see-through) casebacks on genuine automatics reveal a properly finished movement with a branded rotor. If a watch claims to be a Tissot Powermatic 80 but the movement visible through the caseback has no rotor decoration, incorrect finishing or a rotor marked with a different caliber name, something is wrong. Solid casebacks on genuine watches are typically engraved with model number, serial number, water resistance and case material — check that these match the watch's published specs.

6. Cross-Reference the Serial Number

Most established watch brands maintain serial number databases or can verify authenticity through their customer service. The serial number should be present, legible and consistently applied (not stamped unevenly or laser-engraved poorly). For watches purchased from Amazon.com directly or from authorized Amazon sellers, you have platform-level purchase protection — fakes are far more common in private sale markets.

7. Apply the Price Reality Test

A new Tissot PRX Powermatic 80 retails at around $675 on Amazon.com. If someone is offering one for $150, the mathematics of counterfeit detection are simple: no legitimate seller can source a genuine Tissot for less than wholesale. Extreme discounts on prestigious models are the single most reliable predictor of counterfeits. Prices somewhat below MSRP are normal for grey market dealers; prices 70% below MSRP are not.

8. Buy From Verified Sources

The most reliable protection against counterfeits is purchasing from verifiable sources: authorized dealers, brand-owned stores, or established platforms with return policies and authenticity guarantees. Amazon.com's "Sold by" and "Fulfilled by Amazon" designations, combined with their A-to-z Guarantee, provide meaningful purchase protection that private sales cannot match.
