Borealis Chaos Black brings angular geometry to a compact automatic

Borealis’s forthcoming Chaos Black sets a deeply textured dial inside an angular steel case. Faceted markers and luminous hands cut across the pattern. The matching bracelet has a quick-adjustment clasp; case width is 39mm and lug-to-lug length is 46.5mm.

The no-date Miyota 9039 is automatic, and water resistance is 100 metres. Borealis lists this reference for pre-order with delivery estimated for late November 2026. That is a shipping window, not a confirmed launch day, and may change. The black dial gives the geometric design its most restrained treatment.
