A rare Sirenes clock by acclaimed glassmaker Rene Lalique is to star in Bonhams' Home & Interiors sale on September 20-21.
It's estimated to bring in £20,000-25,000 ($26,650-33,331).
The extraordinary lot is constructed from frosted glass and displays dancing female figures.
Gemma Mitchell, a specialist in 20th century decorative arts at Bonhams, says: "…it is the legacy and inspiration of Rene's work which maintains the popularity of the luxurious and celebrated Lalique brand today."
On September 19 Bonhams will auction a major collection of Lalique car mascots to raise funds for charity.
