Third-party watch brands, using Seiko movements

To most of calibers Calibercorner delivers a list of watch models using certain caliber - but these lists contain only watches by the brand which owns the certain caliber.

That depends on the movement you are looking at. First, it's important to understand that movements produced by Seiko fall into two categories: Seiko-only calibers and non-Seiko calibers (aka ebauches aka wholesale movements). If you're looking at a Seiko-only caliber (4R35 for example), a movement with the specific caliber number only used in Seiko watches, then you will only find watches by Seiko listed in the known models section.

My question: I'm interesting for watch brands, where movements by Seiko are in use - third-party brands, not owned by Seiko. I'm happy and thankful about brand names as well as links.

If you're looking at a caliber made by Seiko but used in non-Seiko branded watches (NH35A for example), then you can usually find other community members listing known models in the comments section, as well as the known models section of the tech chart at the top of the page.

It's not so much about brands using Seiko-produced movements, as much as it is about watch models containing Seiko-produced movements.. because there are brands that make some watch models with Sellita, some with Seiko, some with Miyota, etc. There are hundred, if not thousands, of different watch models using any given movement.

And, if I already there, I have an additional, terminological question - what do you think, is a watch by third-party brand, who uses Seiko movement, automatically a mod?

No. That would mean that everything about the watch comes down to the movement and that's not the case (pun). While movements dictate most of the design language of a watch, there is more to a watch than its movement: The case, dial, hands, crown, strap, branding, etc, etc. You have to look way back in to horology history to see that once the watch industry developed with mass production underway, different parts were produced by different companies and factories. While there were some vertically integrated watch manufacturers (many of which were USA brands) who made the movement and overall watch, it was not uncommon for a watch company to source different elements of the watch to put together their own product. This is where ebauches come into play. So, just using a movement doesn't make a watch a mod of the movement maker. It just means the watch is using that movement.

 

Interesting conversation here.  I am sure by now if you have checked elsewhere, the answer that you were seeking.  The use of Seiko movements by other manufactures is fairly common.  like wise there are other suppliers of movements both quartz and mechanical.  A great variety of options depending on where you want to go.
