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

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,
