Cazalea offers an in-depth guide to the diverse movements powering Credor timepieces, building on previous posts about the brand's men's and ladies' lines. This comprehensive overview details the quartz, mechanical, and Spring Drive calibers, highlighting how Credor movements prioritize decoration and style over the more functional aspects often seen in Grand Seiko.

Over the past month I have been introducing the Credor line of timepieces. The first two posts presented the higher-priced Credor men's and ladies' lines of watches, and I showed a few of the Credors that I have owned.

In this post I propose to acquaint our community with the movements used in Credor watches. Like Grand Seiko, Credor offers quartz, hand wind and automatic mechanical, as well as Spring Drive calibers. Because Credor  focuses more on style than Grand Seiko, there is more focus on decoration and less on functions like GMT and sport cases (dive, explore, etc.)

Here's a summary of the movements you are likely to find in a Credor. When compared with the equivalent Seiko units, they are plated differently or engraved with different style of decoration. Some movements claim longer running time and/or higher accuracy. Presumably this is due to small quantities being produced, and more care in regulating the movements.

SPRING DRIVE MOVEMENTS

5R77 Moonphase




NOTE: When I visited the Micro Arts studio, I asked why they used a Spring Drive in the sonnerie and minute repeater - due to the $100-400,000 prices, it seemed an unusual choice. The reply was swift "It is our best movement and it is totally silent; all the better to hear the chimes". Keep in mind that the Eichi and the chiming watches are produced in VERY LOW quantities - perhaps 5-50 units over a 3-5 year span of production. Essentially these are the finest money can buy. And thanks to the studio collaborating with Mr Dufour on finishing techniques, the detailing on these watch movements is just about as good as you can get.

7R06 Sonnerie


7R08 Eichi I





7R11 Minute Repeater


7R14 Eichi II


7R87 Big Date

7R88 Date



SUMMARY

Despite Credor having a focus on fashion and stylish products, there is no shortage of choices when it comes to movements!

However, there is a shortage of good images available, especially in regards to the quartz movements. Please buy a Credor, please open it up, and please share your photos!

Cheers,

Cazalea


About the Seiko Credor Ref. 6899

The Credor 6899 is a distinguished ultra-thin mechanical movement produced by Seiko's Micro Artist Studio, known for its exceptional craftsmanship and precision. This caliber is often found in Credor's most refined dress watches, emphasizing elegance and slender profiles. It represents the pinnacle of Seiko's traditional mechanical watchmaking capabilities, showcasing meticulous finishing and assembly.

This manual-winding movement is designed for extreme thinness, allowing for very svelte case designs. The finishing typically includes polished bevels, Geneva stripes, and blued screws, executed to a high standard. Its compact architecture and precise regulation contribute to its performance within Credor's high-end offerings.

For collectors, the Credor 6899 signifies a commitment to traditional horological artistry and technical mastery. Watches featuring this movement are often limited in production and highly sought after for their discreet luxury and the artisanal skill involved in their creation, making them significant pieces within the Credor lineage.

After reading your series of posts, I have learned so much more about Credor and I respect the brand so much more as well! Can you please tell me, are their movements finished/made at a separate facility from where the Grand Seiko movements are made or are they just finished at the Credor facility? Thank you

I'll try to answer it this way: Let's call "Seiko Watch" a virtual company with many facilities and brands, more than 20,000 employees and billions of dollars in annual sales.. The "Credor Team," "Grand Seiko Team" etc. in Tokyo HQ decides what they want to produce and sell, and they tap other divisions to make the watches for them. The main producers are Seiko Instruments' Morioka Shizukuishi Watch Studio (north central Japan) who make fine mechanical (and some quartz) movements and assemble wa
