Is your Tudor
authentic?
Tudor is Rolex's sister brand, founded by Hans Wilsdorf in 1926. With growing popularity and value retention, Tudor watches have become increasingly targeted by counterfeiters. Here's how to authenticate yours.
How to authenticate a Tudor
Tudor Shield Logo
Modern Tudor watches feature a shield logo on the dial and crown. The shield should have crisp, precise printing with correct proportions—not too wide or tall. Vintage models (pre-1969) used a Tudor rose logo. Check that the logo matches the production year. Counterfeits often have distorted or poorly defined shields.
Snowflake Hour Hand
Tudor's iconic "snowflake" hour hand has a distinctive square tip, first introduced in 1969 on the Submariner. The shape should be perfectly symmetric with sharp, clean edges. Counterfeit hands often have uneven edges, wrong proportions, or poorly applied lume. Not all Tudor models use snowflake hands—Pelagos uses angular hands, Black Bay 58 uses gilt pointed hands.
In-House Manufacture Movements
Since 2015, Tudor has used in-house COSC-certified movements (caliber MT5602, MT5612, MT5813) with 70-hour power reserves and silicon balance springs. Older models used modified ETA movements. Check the caseback or movement through a display back if present. Counterfeit watches use cheap Chinese movements with poor finishing and short power reserves.
Serial Number & Reference Number
The serial number is engraved between the lugs at 6 o'clock (requires removing the bracelet). The reference number is at 12 o'clock. Both should be deeply engraved with consistent depth and sharp, clean edges. Verify the serial number with Tudor or an authorized dealer—genuine Tudors have verifiable production records dating back decades.
Case & Bracelet Construction
Tudor uses 316L stainless steel (or titanium on Pelagos) with precise machining and finishing. Cases should have a substantial weight, tight tolerances, and clean brushing/polishing transitions. Tudor bracelets feature solid end links, robust clasps with micro-adjustment, and smooth articulation. Fakes feel hollow, rattle, and have visible gaps between links.
Bezel Alignment & Action
Tudor dive watches use 120-click unidirectional bezels with aluminum or ceramic inserts. The bezel should rotate smoothly with firm, distinct clicks and zero back-play. At the 12 o'clock position, the triangle/pip should align perfectly with the 12 o'clock dial marker. Counterfeit bezels often have wobbly action, misaligned markings, or poorly printed/engraved numerals.
Common signs of a fake Tudor
Distorted Tudor Shield
The Tudor shield logo has specific proportions that counterfeiters struggle to replicate. Fakes often have a shield that's too wide, too narrow, or has incorrect angles on the banner. The shield should be symmetrical with crisp edges. Some fakes also misplace the shield's vertical position on the dial.
Poorly Finished Snowflake Hands
Counterfeit snowflake hands often have uneven edges, asymmetric tips, or poorly applied lume that doesn't fill the hand cavity properly. The lume should be smooth, evenly applied, and glow bright green or blue (depending on the model). Fake lume is often grainy, uneven, or glows weakly.
Dial Text Spacing Errors
Check the spacing and font of "TUDOR" and "SWISS MADE" text on the dial. Counterfeit dials often have incorrect kerning (letter spacing), wrong font weight, or misaligned text. The "ROTOR SELF-WINDING" or "MANUFACTURE" text (on in-house movement models) should also match authentic examples exactly.
Weak or Misaligned Bezel Clicks
Genuine Tudor bezels rotate counterclockwise only (on dive models) with 120 firm, precise clicks. Each click should feel distinct with no sloppiness or back-play. When the triangle aligns at 12 o'clock, it should be perfectly centered. Counterfeit bezels often wobble, have uneven click tension, or misalign by several degrees.

Frequently asked questions
What's the difference between Tudor and Rolex?
Tudor is Rolex's sister brand, founded by Hans Wilsdorf in 1926. Tudor uses Rolex-quality cases and bracelets but with different movements (including in-house calibers) at more accessible prices. Both brands share the same commitment to quality.
Does Tudor make their own movements?
Yes, Tudor has developed in-house calibers like the MT5602 and MT5813. These movements offer 70-hour power reserves and COSC chronometer certification. Some older Tudor models used modified ETA movements.
Is the Tudor Black Bay a good value?
The Black Bay line is widely considered one of the best values in luxury watchmaking. It offers in-house movements, excellent build quality, and strong brand backing at prices well below comparable Rolex models. The Black Bay line holds its value well on the secondary market.
