Decision 01
Keep every visible surface
2,118 case and 771 bezel vertices lie on the new surfaces. Dial and movement sink 1.668 mm instead of shaving the 60 pillars.

HAXĀ
My original concept watch, re-engineered around a Swiss automatic calibre: the surfaces I drew, now with a movement, a sapphire crystal and a crown on the stem axis — 182 parts, screened for interference on the model.
Satin rose-gold case, brown lacquer dial, burgundy enamel, champagne figure.
01 — The product in 10 secondsHAXĀ
Persian Legacy, Timeless Mastery
- What it is
- A 10.25 mm automatic watch with a Persian winged figure on a hexagon field, in three colourways.
- Who it is for
- Watch collectors drawn to sculptural dial work and culturally rooted mechanical watch design.
- The problem
- The original was a styling model: a solid case, a 0.22 mm sheet for a crystal and no movement inside.
- What is different
- The same visible surfaces, now with a Sellita SW300-1 inside, a 1.20 mm sapphire, a crown on the stem axis and a bracelet with end links and a clasp — every part screened for interference on the model.

02 — The design challenge
The original could not exist.
HAXĀ began as a KeyShot centrepiece. As modelled, the case was solid, the crystal was a 0.22 mm sheet, the hands overlapped in height and nothing sat inside. The 2026 model had to keep every visible surface and make room for real watchmaking.
Original render and 2026 model — different cameras and lighting, so compare the geometry, not the mood.
03 — My contributionOwn design, re-engineered
What I did.
My own design: the original and its 2026 re-engineering.
- Original watch design: case, dial art, bracelet
- Rhino modelling
- Re-engineering around the calibre envelope
- Interference screen
- Technical drawings
- Renders and motion

The decisions that shaped it.
Decision 02
A real calibre inside
A Sellita SW300-1 automatic, modelled inside its published envelope: 71 parts. Internal geometry is representative where the data sheet stops.
Supplier spec · Sellita
Decision 03
Sapphire under the bezel
A 1.20 mm sapphire is fitted from inside under a 0.50 mm bezel lip; the caseback steps 0.97 mm below the original case.
Measured on model
Decision 04
Crown on the stem axis
The crown moves down 0.168 mm onto the calibre’s stem axis; the hands are regrouped and restacked on Sellita heights.

05 — Product architecture & engineeringCAD-developed concept
How it is built.
CAD-developed architecture: 182 parts — 71 movement, 75 bracelet, 36 case, dial and hands — and an interference screen that found no unintended contact above 0.01 mm. Movement internals are representative, inside Sellita’s published envelope.

Engineering notes the longer story
HAXĀ began as a portfolio centrepiece: a sculpted Persian winged figure on a hexagon field, rendered in KeyShot. It looked like a watch, but it was a solid case with a 0.22 mm sheet for a crystal and no movement inside.
In 2026 I re-engineered it around a real movement. The visible surfaces stay exactly as I drew them — 2,118 case and 771 bezel vertices lie on the new surfaces — and the inside is new: a Sellita SW300-1 automatic modelled to its published envelope, a 1.20 mm sapphire under a 0.50 mm bezel lip, a crown on the stem axis, and hands restacked on the calibre's heights.
