Understanding Seiko watch references?

1. Understanding the Structure of Seiko References

Seiko model numbers are often structured in a specific way, and each part of the reference can give you clues about the type and generation of the watch. Here's an example:

Example: Seiko SRP777

  • SRP : This part of the code refers to the model's series or family. Here, SRP indicates a model from the "Samurai" range.
  • 7 : The number "7" in this case designates the generation of the Seiko movement used. The movement is often a 4R36 , which is an automatic movement with a 41-hour power reserve and a day/date display.
  • 777 : The last three digits designate a specific model within the range. For example, "777" is a reference for a popular version of the Seiko Samurai, which features a blue dial.

Other examples:

  • SBDC : Models from the "Shogun" range.
  • SKX : Popular diving models like the SKX007 , with a 7S26 caliber.
