The choice is therefore chiefly about which restrained color combination suits you: ochre yellow, terracotta red, muted green or dark mineral tones.
What distinguishes the four Tetra Origins watches?
NOMOS names the four variants Tetra Ochra, Tetra Terra, Tetra Salvia and Tetra Basalt. The brand describes the collection’s dials as muted, nature-inspired shades, paired with contrasting small-seconds accents. Its product page describes the colors as follows:
| Model | Reference | Dial color |
|---|---|---|
| Tetra Ochra | 437 / 437.SB | Ochre yellow |
| Tetra Terra | 438 / 438.SB | Terracotta red, shown in rose tones |
| Tetra Salvia | 439 / 439.SB | Muted green |
| Tetra Basalt | 440 / 440.SB | Dark mineral tone |
These color descriptions are the substantiated basis for choosing among the references. The published information does not establish that one version is more accurate, durable or technically advanced than another. NOMOS Tetra Origins
What do all four watches share?
Each Tetra Origins has a square case measuring 29.5 by 29.5 millimeters and uses NOMOS’s hand-wound DUW 4001 caliber with the brand’s proprietary swing system. NOMOS lists a 53-hour power reserve, stop-seconds mechanism and regulation in six positions for the caliber. These are manufacturer-published specifications, not independent measurements; the official information reviewed does not describe mechanical differences between the color variants.

Which color should you choose?
Start with the dial rather than looking for a mechanical advantage the published specifications do not establish. Ochra is the warm yellow option; Terra brings a terracotta or rose-toned look; Salvia is green; and Basalt offers the darkest, mineral-like palette. Then consider how the small-seconds accent contrasts with the main dial. Seeing the colors in person or comparing current product photographs may help if subtle differences matter to you.
