The SR620-1 is the bolder, more dramatic expression ofHeritage V72. Its velvety matte intense black dial creates maximum contrast against the warmth of the 18-carat yellow solid gold (1N) case. The result is immediate, elegant and quietly powerful. The black surface gives depth and restraint,while the gold case brings light, warmth and a sense of preciousness without excess. At the centre of this composition the three subdials standout thanks to the champagne azurage, adding a refined circular texture that catches the light with subtle movement.It does not shout. It glows. It creates a dialogue between darkness and radiance, between the sobriety of black and the richness of gold. The 18-carat yellow solid gold (1N) pin buckle completes the composition, extending the warmth of the case in to the strap architecture.
