The piece holds because the structure was planned first
When a design has moving parts, hollow forms, or several pieces that must meet cleanly, the difference between a sample that wows and one that comes back cracked is decided long before the first cut. We plan the joints, the wall thickness, and the parting lines up front, so the finished piece behaves the way your drawing promises and survives the life your client gives it.
The problem this solves
What breaks when structure is left to chance
Most rejected first samples are not rejected for how they look. They are rejected because something inside did not hold. A hinge that binds after a week. A hollow form that collapses where the wall thinned. A seam that flashes in the light because it was placed on a visible face. These are not finish problems, they are structure problems, and they are far cheaper to prevent than to discover once metal has been cut and set.
The expensive version is the one that reaches your client before it fails. A launch gets pushed, a batch gets reworked, and the confidence you built with that buyer takes the real hit. None of it shows up in a flat rendering, which is exactly why it slips through until the piece is already in someone's hands and being worn to dinner.
A structure problem is also a trust problem. When a buyer receives a piece that fails in the first month, they rarely blame the drawing. They blame the maker. One weak joint can cost the relationship that took years to build, and the referral that would have come from it. Settling structure early is how we protect both the piece and the account behind it.
We treat structure as the first thing to settle, not the last thing to hope for. Before any metal is committed, we decide how the piece comes apart, where it takes load, and which lines the eye will actually trace. That discipline is what turns a risky design into a repeatable one.
The pieces that fail are rarely the ones that looked hard. They are the ones whose inside was never planned.
What we do instead
Four structure calls we make before metal is cut
We map every seam before the first part
You tell us which edges meet and which parts move. We return a structure note that names each seam, its direction, and whether it is welded, hinged, or assembled, so nothing is decided at the bench by habit. When a join is named in advance, it can be checked, not discovered.
Hollow where it should be light, solid where it loads
A cuff that is hollow to wear comfortably is useless if the wall thins at the stress point. We set wall thickness per zone from the model, not from a guess, and keep mass where the piece actually takes force. The result feels substantial in the hand and stays rigid on the wrist.
Parting lines go where the eye never lands
Every multi-part piece needs a line where two halves meet. We place it on a hidden or structural face, so the join reads as design intent rather than a repair. Your client never sees the seam, only the clean silhouette you drew.
Assembly is built to come apart for service
When a stone needs resetting or a joint needs attention years later, a piece that was fused shut becomes a liability. We design reversible assembly wherever the design allows it, so the piece can be serviced without being rebuilt from scratch.
How it works
From your drawing to a structure you have signed off
You send the drawing and the moving parts
A CAD file, a scan, or a clear sketch, plus a one-line note on which parts move, bear load, or must come apart. We accept the common CAD and mesh formats, and if you only have a render we will tell you what we still need. See how we handle files on the CAD & 3D Prototyping page.
We return a structure note
Before cutting, you get a written read on seams, wall thickness per zone, and parting-line placement. It lists what we would change and why, so you can approve, adjust, or ask before any material is committed. No silent decisions at the bench, no surprises in the sample.
You review the rendered model and weight
We model the assembly and show you the piece from the angles that matter, including the hidden faces a render would hide, with a weight figure you can plan around. You see the inside before it is made, not after.
We build the first sectioned sample
One prototype that proves the joints hold and the parts align. You can hold it, pull it apart, and see exactly what the production piece will be. If something is off, it is a cheap change at this stage, not an expensive one later.
Your approval gates the full piece
Nothing scales to a batch until you have signed off the structure. The second piece matches the first because the plan, not the bench, drives it, and every later piece inherits the same documented plan.
Risk reversal
What you are not exposed to
Seams that flash in the light
We place parting lines on hidden or structural faces, so the join reads as intent, not a repair. The seam exists, it simply never meets the eye.
A joint that fails after delivery
Assembly is tested before sign-off. A hinge that binds or a catch that slips is caught on the sample, not on your client's wrist, where the cost is a relationship, not a rework fee.
A rebuild that changes the look
Because assembly is reversible by design, service and reset work do not require remaking the piece from scratch. The piece your client fell in love with stays the piece they keep.
Surprises at the weight line
Weight is decided in the model, per zone, before metal. What you approve is what gets made, so the piece that arrives weighs what the drawing promised.
Proof
See the work, not the promises
A rivière rebuilt as sections
How a continuous line was broken into serviced segments without losing the look, so a future reset never means a rebuild.

A moving part joined so the seam disappears on the worn face, with the motion tested before the sample ships.

Wall thickness planned per zone so a light piece stays rigid, and the mass sits exactly where the design takes force.

See how we workWhat we need from you
Less than you think
- Your drawing, CAD, scan, or a sketch clear enough to read the moving parts. A rough sketch beats a perfect idea we cannot see.
- One line on what moves, what bears load, and what must come apart, so we plan the joints instead of guessing them.
- The metal you want it in, so wall thickness and weight are planned for that alloy rather than corrected after the fact.
- Any reference piece you have worn or liked, to anchor the feel and the proportion you are aiming for.
- The context for your timeline, so we plan the structure to fit it without promising a date we cannot keep.
- Questions, early. The sooner a structural call is raised, the cheaper it is to change, and the safer the sample becomes.
Questions buyers actually ask
QCan you work from a sketch without a CAD file?
Yes. A clear sketch plus a note on the moving parts is enough to start a structure conversation. We model it and show you the seams before cutting, so you are never approving something you cannot picture.
QWhat if my design is too fragile to wear?
That is exactly what the structure note is for. We tell you early where the design needs more mass or a different joint, before metal is committed, and we propose the smallest change that makes it wearable.
QDo you glue parts together?
Only where a design truly requires it, and never as a substitute for a real joint. Where we can, assembly is mechanical and reversible so the piece can be serviced, which protects its value over time.
QHow do I know the sample matches production?
The first sample is built from the same plan the batch uses. Your approval of the structure gates production, so the second piece matches the first and the hundredth matches the second.
QCan a finished piece be taken apart for repair later?
When the design allows, yes. We build reversible assembly on purpose. For fused or welded sections we tell you up front what future service will involve, so there are no surprises years down the line.
QWill the parting line show on the finished piece?
We place parting lines on hidden or structural faces by default. If a line must fall on a visible edge, we discuss the finish options with you before the sample is built, never after.
Send the structure you are not sure will hold
If a design has parts that move, hollow forms, or seams you are not certain about, that is the right time to talk, before metal is cut. Send the drawing and the one line on what moves, and we will come back with a structure read that names every seam, every wall, and every parting line. You decide from there.
