bounding evidence — no range is drawn on the era axis
not after 2026
a source states this range, 2026“For 2026, these newly updated models span a litany of dial executions across 40, 36, and 30mm versions in both steel and two-tone. The new Royals also get a new selection of in-house Manufacture Calibers across all sizes: the MT5633 (40mm),”
Identity
A caliber is three separate things and this reference keeps them apart: the construction, the names it is sold under, and the article a brand actually bought. A watch model points at an execution — never at a bare construction — which is why “same caliber” is almost never a complete answer.
