What does "in-house" actually mean in watchmaking?
"In-house" means the maker did the work themselves, in their own workshop, with their own hands and machines. That is the whole definition. It is also the whole problem, because nothing requires anyone to say which work.
So here is the sentence worth keeping: in watchmaking, in-house is a claim about where a piece of work was done. It is not a measure of quality. No law defines it. No body audits it. The same two words can cover a workshop that cuts its own plates from raw brass and a company whose every part is made by suppliers to its own drawings, and both can use them honestly.
The same two words doing six different jobs
Designed in-house. The drawings belong to the brand; the parts are made by suppliers to those drawings. That is real work and real cost, and it is not the same as making the parts. "Designed in-house" and "in-house" are two claims sharing a word.
Assembled in-house. Parts arrive from elsewhere. The watch is put together, regulated and controlled by the brand.
Finished in-house. The components are bought; the surfaces are the brand's own work. Bevelling, frosting, striping, bluing.
Modified in-house. A bought base calibre — the trade word is ébauche, a movement supplied as a foundation for someone else to build on — is altered, refinished, or given an added module. That is where we are, and the full list is further down.
Made inside the same group. The movement comes from a sister company under a shared owner. True, and a different thing from a workshop making it under its own roof.
Designed and manufactured from raw material by the same people. The rarest reading, and the one most people picture when they read the words.
All six get printed as "in-house". None of them is dishonest by itself. The distance between them is why the phrase on its own tells you almost nothing.
Nobody audits it
Some things about a watch are defined in law — country-of-origin labelling, for one, with thresholds you can look up and argue about. "In-house" has nothing behind it. Its meaning is set by whoever prints it.
Which is why arguing about the word gets you nowhere, and asking for the list gets you an answer.
Does it matter?
Less than the argument around it suggests, and not in the way it suggests.
For whether the watch keeps working, a well-made bought calibre that any competent watchmaker can open, service and find parts for is an advantage to the owner, not a compromise. A movement that exists nowhere else is a servicing question for whoever owns the watch after you.
Where it does matter is responsibility. Every operation done in our own workshop is one where we cannot point at a supplier when it comes out wrong. That is why we pull work inward. Not because the phrase reads well.
And the defence of a modified base calibre is not that it is secretly in-house. It is this: we chose it deliberately, we name it out loud, we can tell you exactly what we changed, and the movement underneath is one other watchmakers already know.
Our list, in full
The Octagon, Cornerstone series. What we do ourselves, in Jyväskylä:
Design and engineering. Case and crown machining and hand-finishing — 316L stainless steel, octagonal, brushed and polished by hand. The dial: 22 individual parts, a glass-bead-blasted anodized aluminium ground, silver indices, and the mesh woven by hand from 0.4 mm sterling silver wire. The hands: 0.2 mm carbon steel, cut, filed and heat-blued here. Modification of the movement and its "Rippling" finish. Assembly, regulation and final control.
What we buy, and from whom:
The base calibre — a Swiss ETA 6498, manual winding, which we modify and refinish. The strap, handmade in black calf with goat-leather lining, from a Finnish leather artisan who is better at leather than I will ever be. The box, from a specialist. The sapphire crystal — custom faceted — and the gaskets. Both need machinery this workshop does not have.
What I have not done
I am a graduated micromechanic from the Finnish School of Watchmaking in Espoo, 2024. I intend to sit the master watchmaker's examination in the future. I have not sat it, and the word "master" stays away from my name until I do.
We are willing to make every part of a one-off commission from raw material, the movement included, if that is what the client asks for. That is a stated willingness, not a finished track record. The nearest thing I have done is building a wall-clock movement — the whole mechanism — during an Erasmus+ project with a French horology school in Morteau. A wall clock is not a wristwatch, and I won't let the two be quietly confused.
What to ask any maker, including us
Ask which parts were made in their own workshop, named one by one, and which were bought. Ask who made the movement, and precisely what was changed. Ask to see photographs or video of the movement before it is cased. Ask who made the case, and where. Ask whether a competent watchmaker elsewhere can service the watch, and whether the parts are standard. Ask what is in writing before any money moves — ours is five years of warranty from delivery with the first full service included, and fourteen days to return the watch unworn and in its original condition.
Then ask the one that sorts makers fastest: what don't you make?
A maker who does the work knows where their capability stops. Ours is above, in full — reach@reigi.fi if you want more detail, or come and see the place by appointment.
