Which companies produce every part in-house?

[Submariner SS]

Currently, which watch brands produce every part in-house, including hair springs? I would imagine this being a very short list

[OJONES]

Is seiko the only example?

[benlee]

Rolex? But I am not 100% sure on the hairspring.

Seiko, AP, PP

Do AP and PP grow their own quartz crystals like Seiko does?

AP? Seriously?
They use FP base and DD chronograph modules.

And PP isn’t fully vertically integrated either, iirc.

Or formulate their own lubrications?
Seiko employ chemists to do just that, which is then produced for them under contract.

Seiko and Rolex are as close as you’re going to get, but I believe neither are truly 100% vertically integrated, despite what many believe.

Seiko, for example, grows their own quartz crystals, but what about the precious stones that they use for their Credor watches? Are those grown, too? I bet they’re natural.

[Emmanuel69]

I think JLC might make the cut

[Jay (Eire)]

It's a great question because it just evidences the amount of misinformation out there, even among us whom could be considered the more knowledgeable buyer.

[yessir69]

Seiko is the only one I know. It’s a ginormous company.

[yoast]

Moser

[AzHadEnuf]

Nomos

[_speedmaster_]

Moser definitely does.
JLC as we'll believe.

You or I misunderstood the question. You are correct in some instances. The royal oak thin or royal oak diver for example are both 100% inhouse.

Lol well if you want to use this as the standard then nobody is 100% in house. I don’t think anybody produce the steels themselves either.

But yeah I think Seiko is probably the closest and then Rolex.

Parmigiani comes close i think as they are vertically integrated.

We’re not talking about in-house movements were talking about producing every component in-house. Typically many brands use 3rd parties to make the cases or more commonly dials. Not many brands can make their own dials for example or hair springs. AP definiately does not make every part in-house.

Rolex has their own foundries. They produce their own steel, gold and platinum. I've never heard Seiko or anybody else make that claim.

Some blogs have mentioned that Seiko is 100% in house, but I've never seen an official statement from Seiko.

And you're right. That's my point. Nobody is 100% vertically integrated. That would be, for all intents and purposes, impossible. Being vertically integrated is cool, but it doesn't really matter. It doesn't really speak to the quality or craftsmanship of the end product. Just look at PP and AP. Both are top tier brands and don't hide the fact that they're not vertically integrated.

Moser is the one that came to my mind.

Damasko produces its own ice-hardened nickel free SS

I'll represent the German watchmaker brand, Damasko again with their in-house A35 (Automatic) and H35 (hand wound) movements and in-house Silicon EPS hair springs.They make all their watch components

Nope... Rolex’s (presumably on-site) foundry deals only with precious metal production, especially since Everose is a proprietary composition of RG.
The 904L is standard stuff, so is just bought in.
I’m assuming, with doing the three colours of gold, that they may as well do the standard Platinium also, but it may be supplied too.

Just checked on the web site and indeed you're correct. Thanks for pointing this out
