Balance is the key to the "Grace" collection, which both basic horological technologies share peaceably. The two-hands steel model that WorldTempus has recently introduced, was equipped with a quartz movement.
Ref 2944.54.76.1334 (stainless steel) and 2944.75.79.0502 (pink gold), highlighted today,  house a self-winding mechanical movement with 42h of power reserve.
Both feature a burgundy dial with 3 diamonds. Other diamonds -  6 - adorn the case of the steel model, while the more precious rose-gold Grace shine with 60 diamonds.
