This ref. 5030 is truly beautiful and your example is really lovely.
The reference also exists with leaf hands, generally with painted Arabic numerals.
But there is a very rare and, to my eyes, absolutely wonderful variant with a black dial and diamond indexes.
Vacheron Constantin has also done a no-date, no-seconds hand version, ref. 31150 with Breguet numerals and textured dial.
Best, Emmanuel
