When Ponti Gennari made your bracelet in the 1950s then it looked like the watch on the left (Patek Philippe ref2551). When Ponti Gennari did it approx 15y later in the early 1970s ff. then it looked like the fire-finishing on the right -- and it did not change since that day anymore as it reached perfection in that.

Piaget, who integrated the Geneva goldsmith-artisans Ponti Gennari in the mid 1960s, calls this finishing Palace Decor, nowadays. Not exactly matching the lively reflections of the thousand facets, in my opinion.
