**Model:** Seiko Credor GCLL992 / 5R77-0AA0 **Year:** January 2006 **Album**: [https://imgur.com/a/SK83oFJ](https://imgur.com/a/SK83oFJ) **Timestamp:**  [https://imgur.com/a/9PCympI](https://imgur.com/a/9PCympI) **Features:** **The Design.** Its rich chocolate dial is paired with a solid 18kt rose gold bezel and indices, creating a warm, opulent aesthetic. The additional weight of the gold is perfectly counterbalanced by the lightweight titanium case, ensuring exceptional comfort for all-day wear. The finishing is immaculate, and small details like rose gold moon shouldn't go unnoticed. And what does a face as stunning as this one deserve? Only the smoothest sweep imaginable, of course. Thankfully, Credor delivers, equipping the GCLL992 Moonphase with the exceptional 5R77 Spring Drive movement. **The Complication.** One common complaint among collectors is the inclusion of date windows on most Grand Seiko Spring Drives. While I’m not opposed to date windows, I understand the complaint - Spring Drive watches exude elegance, and date windows can feel jarringly intrusive. Luckily, Credor’s Spring Drive offerings tend to forgo date windows, preserving their dressy heritage.  **The Balance.** It strikes a masterful balance. Its Moonphase and Power Reserve indicators are tastefully understated, ensuring the twinkling, zaratsu polishing is the star of the show. **The Movement.** The GLCC992 houses Credor's 5R77 movement, which is one of very few Spring Drive Moonphases in existence. Accurate to +/- 15 seconds per month, and with a 72-hour power reserve. **Details:** **Condition:** In very good condition overall. A clean dial and crystal, with minor marks on the case and bezel.
