SPECUS / ART OBJECT NO. 01
Pin Field Cosmogram
01 / PHYSICAL OBJECT
A stellar field with a physical interface
Art Object No. 01 transfers the approved 42 mm geometry of SA-1 to a 420 mm wall format. The enlarged field retains the real mounting logic of the watch modules, so scale becomes a physical connection rather than a graphic quotation.
- Format
- 420 × 420 mm
- Depth
- 25–40 mm
- Fastening
- M2 screws and nuts
- Installation
- Open wall-mounted object
- Materials
- Metal, black textolite, spacers
- Status
- 3D volume prototype
02 / TWO SCALES
42 mm → 420 mm
The overall geometry is enlarged ten times. Local mounting groups remain at 1:1 scale with SA-1. A marker, bumper, or protective ring can therefore belong to both the watch and the wall object after the interface passes mechanical testing.
03 / STELLAR FIELD
Polar Atlas J2000.0
The first state is calculated from the Hipparcos I/239 catalogue in a north-polar stereographic projection. Polaris occupies the upper orientation point. Its catalogue position remains recorded near the celestial pole, preserving the difference between the physical anchor and the astronomical coordinate.
04 / CONSTRUCTION
Open modular surface
Nominal 2.00 mm holes form single, paired, and four-point groups based on SA-1 mounting configurations. The central plate is removable. Markers can be rearranged and archived; final fits, loads, wear, and safety remain subject to prototype testing.
05 / SERIES
One geometry, several material states
The series keeps one map, scale, and mounting grammar. Material, surface treatment, color, and the active marker vary between versions.
No. 01-A
Black textolite / metal
Dark base with a yellow Polaris marker
No. 01-B
Satin steel / engraving
Cold museum-engineering state
No. 01-C
Graphite metal / PVD
Near-monochrome archival state
CURRENT STAGE
The first full-size version will be 3D printed.
The volume test will verify depth, wall presence, access to fasteners, removable modules, and the 420 mm format before metal production.
