In 1916, Montenegro established a consular mission in Geneva, and Piguet was considered for the position of honorary consul.

In her Twenty Years Of Balkan Tangle, Edith Durham recalls Piguet as a "truly tactful man" who would often defuse heated altercations between the Foreign Ministers Plenipotentiary.

[5] Henrik Angell describes him in Gjennem Montenegro paa Ski as a "diligent man, working all day despite the cold", as well as a "huge, handsome fellow, naturalized Montenegrin".

[6] In his memoir Bilješke jednog pisca, Simo Matavulj writes of his friendship with Piguet, who he says had a "poetic soul and extensive literary education".

He describes Piguet as a "mystic and convinced spiritist", which he preached with "proselytizing zeal".
