The data includes both men's and ladies models and attempts to record the details for all models released. There are currently over 700 individual models included.

Modern Grand Seiko Information Update

The data is broken down into the following fields and has been classified as below.

Model The model number of the watch. This is traditionally 4 characters and then 3 digits e.g.  SBGA001. Occasionally the last 3 characters include a letter and not numerals but this is usually reserved for special models. Model numbers may also include a trailing character to differentiate sales region but this I excluded as the model features themselves remain consistent between areas.
Movement Type General type of movement used in watch e.g. Quartz, Mechanical or Spring Drive. The mechanical models are broken into Automatic, Manual (Hand Winding) and Hi-Beat Automatic. If an automatic model also supports hand winding it is still listed as Mechanical Automatic. Spring Drive models are Automatic or Manual.
Calibre Movement calibre number. If there are multiple generational versions e.g. A, B, C this is not specified.
Case code This is the second part of the code on the case back of the watch. The first half of the complete code is the calibre (4 characters) and the second half (4 characters) is the case code. These codes are not unique as models that share the movement and case design will have the same MVMT-CASE code.
Case Material The material of the main case body.
Bezel Material and design of the bezel. If the material differs from the main case material it is noted, if the bezel and case material are the same it is not noted. If the design of the bezel is different than a standard smooth design it is also noted.
Width (mm) Width of the watch in millimeters excluding the crown.
Strap/Bracelet Is the watch supplied with a bracelet, strap, both or multiple straps.
Part#/Size Part # for the bracelet, if supplied with a strap the lug width in millimeters is noted.

Edition If the watch is a Special Edition, Limited Edition or limited distribution it is noted. If a model is limited distribution but available through multiple retailers then the widest distribution channel is noted. For example if available through GS Boutiques, GS Premium Salons and GS Mastershops it is listed as a Mastershop model as the GS Salons and Boutiques have access to all Mastershop models.
