An E Howard & Co No 46 Astronomical Regulator clock realised $130,000 at Keno Auctions on October 30.
The clock is among the most desirable models in the world due to the complexity and precision of its mechanism along with its classic design.
Founded in 1858, E Howard & Co was well-known for producing high quality watches and regulators.
The brand became associated with wealth and prestige in the late 19th century, producing the majority of its clocks to order. The walnut casing of this example would have been among the most expensive options available to buyers at the time.
A No 46 sold for $230,100 in 2012, a record for an E Howard & Co clock.
Yun Gee's Double Self Portrait (1926) realised a 70% increase on its estimate of $10,000-20,000 - ultimately achieving $34,000.
Gee (1906-193) was the first Chinese artist to exhibit in San Francisco, Paris and New York.
His work was influenced by cubism and he exhibited with artists in Europe and America, but often faced discrimination - especially in the US where his achievements were marginalised.
In recent years his work has risen in value due in large part to the influence of Chinese art collectors, who recognise the significance of his work. His Nudes on Horseback achieved $1.5m at Christie's in Hong Kong in May of this year - a record price for a painting by Gee.
We have this signed postcard from the father of the cubist movement, Pablo Picasso.
