# Reference: **Model**: Credor “Pacific” GCBG975 / 4S77-00B0  **Year**: August 2003 **Album**: [https://imgur.com/a/RYQMCc6](https://imgur.com/a/RYQMCc6) **Timestamp:** [https://imgur.com/a/KixNB8Y](https://imgur.com/a/KixNB8Y) # Features: ***The Design.***  The "Pacific" caseback pays homage to Japan’s ancient maritime history.  ***The Movement.*** At the time, the 4S77 was one of the most complicated automatic movements Seiko made. In the early 1990s, the 4S calibre was born from Seiko’s desire to recapture the high precision and excellence of their 1970s Chronometer Certified 52 calibre. Delighted with the results of the 4S, Seiko committed to producing 200,000 units - their largest single calibre production run to date. Thanks to its ambitious production volume and versatile design (with 13 variants in total), the 4S movement found its way into various Seiko models in the '90s and early 2000s - many of which are now considered iconic by collectors, like this GCBG975 Credor. ***The Complication.*** The secondary crown allows you to jump the hour hand in one-hour increments, without affecting the minute and second hands or the 24-hour subdial. While it might not look like a traditional GMT as its 24 -hour hand is on a subdial, the secondary crown makes this watch a "True" or "Traveller" GMT. Additionally, the 4S77 movement offers a 50-hour power reserve, a retrograde day function, and a circular date pointer. It’s a lot of watch for the current price, especially considering originally retailed in Japan at ¥320,000 in 2003 (around $2900 USD at the time, not adjusted for inflation). ***The Shape***. The 39mm wide tonneau case is as universally sized as a watch can be - you’d need particularly large or small wrists for this shape not to suit you. It comes with the original metal bracelet, suitable for up to 7.2 inch wrists. Shown on my 6.5 inch wrist in the video/pictures. # Details: **Condition**: In great condition.
