Model: Seiko Credor GCLL999 / 5R77-0AA0
Year: January 2006
Features:
The Design. Midnight blue and and silver is a colour combination made in heaven. It’s practically a cheat code for creating a sleek, distinguished piece. And what does a face as stunning as this one deserve? Only the smoothest sweep imaginable, of course. Thankfully, Credor delivers, equipping the GCLL999 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-polished indices, hands, and case remain the stars of the show.
The Movement. The GLCC999 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.

Are your watches water resistant?
All of our watch mods are tested by our own pressure depth testing equipment, and are guaranteed to resistant water up to 50m of depth. Seiko Originals have varied levels of depth resistance, which will be stated in the description of each watch.
Can I modify an existing design?
We welcome all ideas! Get in touch via the Contact Us page and we can let you know the possibility and cost of any potential alterations.
What is your returns policy?
Due to the hand-made nature of the Seiko Mods, we offer a 7 day returns period after the watch has been received. The returner must bear the cost of the returns, and the watch must be returned in the same condition as it arrived. We do not offer returns on any bespoke or custom-made watches.
Due to the vintage nature of the Seiko Originals, returns are considered on a case-by-case basis, as vintage items typically have a no returns policy.
