Step 1: Serial Number

All modern Seiko watches have the date of manufacture contained in the 6 digit Serial number. Exceptions are pre-1970 models when the numbers were 7 digits long, and limited edition models may have a number reflecting it's piece number e.g. 90/200 meaning its the 90th of only 200 pieces. Also check that the engraving is neat, evenly spaced, aligned and features sharp edges.

The 2020 62MAS-inspired Prospex SPB line has been one of the most sought after in the market and currently is trading hot in the secondary market.

Step 2: Movement Model

The Seiko movement and model number can be found on the caseback in two sets of 4 digits joined by a dash. The first 4 are the movement calibre number, the second four are the case/model number. Also check that the engraving is neat, evenly spaced, aligned and features sharp edges.

Step 3: Movement Dial

Seiko watches feature the movement calibre and dial code printed at the bottom of the dial near the 6 o'clock position.

Step 4: Logo

Every Seiko watch will feature the Seiko logo on the watch face (dial). Check the size and shape of the letters extremely carefully for any slight variation.

Step 5: Instruction Booklet

If the seller photographed the instruction booklet check that any movement numbers match those found on the watch itself. Also check that the copy is aligned and evenly spaced, and that the colour is sharp. Often counterfeited photocopied booklets lose their colour and definition.

Step 6: Guarantee

New Seiko watches are accompanied by a guarantee certificate. The style and details may vary according to watch model and country. But check that all copy is aligned and evenly spaced. Remember that authentic certificates can accompany counterfeit watches.

eBay provides Authenticity Guarantee and has the largest selection of Seiko watches available online.
