Royal Yeshwant Rao Holkar II spotted wearing a Cartier

Photographed in an elegant profile pose circa 1930, Yeshwant Rao Holkar II — the 26th Maharajah of Indore — is seen lighting a cigarette while seated in formal evening dress. On his wrist sits a notably slim Cartier Tank Rectangle, one of the most architecturally refined watch designs to emerge from the rue de la Paix atelier in that era. The sighting is entirely consistent with Holkar's documented taste for European modernism at its most refined.

The Cartier Tank Rectangle of this period was produced in very limited numbers, typically cased in platinum or white gold to satisfy the Art Deco appetite for cool, reflective metals. Cases measured approximately 23–25mm in length with an even more elongated dial ratio than the standard Tank, featuring a stark white or cream dial with Roman numerals, blued steel sword-hands, and the characteristic chemin de fer minute track. The movement would have been a manual-wind Cartier calibre sourced from Jaeger or LeCoultre, gossamer-thin by the standards of the day. No reference number system was formalised at Cartier in this era; pieces were largely bespoke commissions catalogued by internal order numbers.

For collectors, a Tank Rectangle from this precise period — late 1920s to early 1930s, especially in platinum — occupies a rarefied tier. These are not watches that appear regularly at auction; when they do, at Christie's or Sotheby's Geneva, they command significant premiums above modern Cartier references. Provenance linking a piece to a royal commission, as would be the case here, multiplies that premium considerably.

Yeshwant Rao Holkar II was no ordinary royal patron. He commissioned furniture from Émile-Jacques Ruhlmann, architecture from Eckart Muthesius, and art from Brancusi and Man Ray. His engagement with Cartier was part of a broader, intellectually coherent programme of collecting. The choice of a restrained Tank Rectangle over something jewel-encrusted speaks precisely to his sensibility — luxury expressed through proportion and material, not ostentation.

Estimating market value for a vintage Cartier Tank Rectangle of this exact vintage is difficult without physical examination, but comparable examples in platinum with documented provenance have realised between $40,000 and $120,000 at major auction houses in recent years.
