Source note
Spec backfill (2026-08-07, round 5): Erebus Watches official product pages (erebuswatches.com), cross-checked against a WatchCrunch review. Case/movement specs are shared across the Ascent 41 dial options (this catalog row doesn't pin a specific dial), sourced from the Black Enamel product page as the case-level reference. Jewel count/power reserve for the Miyota 9015 are the movement's standard published spec (not watch-specific, but a well-established off-the-shelf caliber). lug_width_mm=20 already on file matches confirmed spec, no conflict. As expected for a small microbrand, coverage is thin. Unresolved: dial_color (this row isn't tied to one of Erebus's dial options), complications (no date window mentioned in any source found), year_introduced, watch_type.
