Understanding Seiko Watch Models and Variations

Seiko is a Japanese watch brand known for its innovative technology and craftsmanship. The brand has produced a wide range of watches, from affordable quartz models to high-end mechanical timepieces. To identify your Seiko watch, you need to familiarize yourself with the following aspects:

1. Model Number

   • Location: The model number is usually located on the back of the watch case. It is often inscribed directly on the case or on a removable case back.
   • Format: Seiko model numbers typically consist of a combination of letters and numbers. For example, a common model number format is “SKX007” or “SARB033.” The letters often denote the type of watch, while the numbers can indicate specific features or design variations.

2. Serial Number

   • Location: The serial number is also usually found on the case back. It can be a separate engraving from the model number.
   • Format: Seiko serial numbers typically consist of a series of numbers that may include a letter. The letter often represents the year of manufacture. For example, if the letter is “A,” the watch was made in the year 2000; “B” corresponds to 2001, and so forth.

3. Caliber Number

   • Location: The caliber number, which indicates the specific movement used in the watch, can be found on the case back or sometimes on the movement itself if you remove the case back.
